INTRODUCTION 1.1 Description Public alerting and notification in the Seabrook EPZ will be accomplished througn tne activation of sirens, with simultaneous emergency messages broadcast by designated local radio stations.

A public education program is underway and will oe maintained to advise residents of and visitors to the CPZ tnat wnen tne sirens are neard, tney snould tune to the designated radio stations for information aoout an emergency.

A total of 133 nen electronic sirens will be installed in tne CPZ to perform the initial alerting function.

These will

{

be complemented oy seven mechanical sirens recently installed in the City of Henouryport, MA.

Sirens in the State of New Hampsnire will De activated oy radio from the Rockingnam County Police Dispaten Center in Grentwood, New Hampshire.

Those in Massacnusetts will oc activated from State Police Troop A Headquarters in Framingnam, MA.

Tne 23 cities and towns in the CPZ will also nave the capability to activate the sirens witnin their boundaries, if necessary.

The electronic sirens to be installed will have a public-address capability.

Along the public beaches from Newbury, Massachusetts, north througn Hampton, New Hampshire, siren locations nave been chosen so tnat the sirens can provide botn an alerting tone and a public-address nessage to notify transient beach users who may not nave immediate access to commercial radio receivers.

Supplementing the sirens, a total of 234 tone-activated radio receivers will be provided to institutions witnin the EPl that may nave to internally coordinate tneir response to an emergency.

These institutions, (scnools, hospitals, major employers, etc.) have oeen identified from the pertinent local emergency plans.

An additional quantity of tone-activated receivers will be available for distribution to isolated residences if it is determined tnat alerting by siren must be l

-1

supplemented, and where tne provision of siren coverage would De uneconomical.

Further, these receivers provide alerting through a signal light and could be provided to residences where an occupant is hearing-impaired.

The tone-activated radio receivers in each state will receive broadcasts from the designated emergency broadcast station in tnat state.

4 1.2 Design Basis The design objective of the public alerting system for the Seabrook EPZ has been to provide coverage to essentially 100%

of tne populated area of the EPZ.

This has oeen achieved oy following the guidance in Appendix 3.,

Section C. 3.

e.,

of NUREG-0654; entitled "For Organizations Proposing Systems ditnout Field Surveys."

An additional margin of about 5 decioels (dB) has been added within 10 miles of the site.

In order to verify tne design guidance that was used, selected measurements.were made of ambient background noise, and outdoor sound propagation was. computed for a variety of local weather conditions.

These studies confirmed that the design guidance followed was appropriate and conservative.

1.3 Summary In Section 2 of this Design Report, the topography, climatology, demography and ambient noise environment of the EPZ are summarized as they pertain to siren coverage.

Section 3 contains a detailed technical description of the alerting system.

An analysis of the anticipated performance of the system is given in Section 4 Appendices include measured background noise data, equipment procurement and insta,llation specifications, and computation procedures.

2.

DESCRIPTION OF THE SEABROOK STATION PLUME EXPOSURE EPZ Tnis description is limited to those features of the EPZ that affect the performance of public alerting systems using sirens.

.2.1 Topography Sound propagation over the ground, such as from a siren to a li'stener, is affected by the terrain.

Tne largest such effect is shielding by hills and the walls of valleys.

However, extensive forests can attenuate the sound, and the sound-reflecting properties of the ground are important as well.

Seabrook Station is on a coastal plain about 1 1/2 miles inland from the Atlantic Ocean (see Fig. 2.1).

Inis plain, extending from the shore to about 4 miles inland, is essentially flat, witn no hills or valleys to impede sound propagation.

The coastline itself is rocky on the north, changing to sandy beaches on tne south.

Over most of the southern half'of tne EPZ, the beaches are actually Darrier islands separated from the mainland by 1-2 miles of uninhabited tidal estuaries and salt marshes.

Inland of the coastal plain the land gradually rises.

To the north, there are scattered, symmetrical nills 200-300 feet in elevation - apparently drumlins or morainic remnants.

These tend to be oriented along northwesterly to southeasterly lines.

To the south, particularly along the Merrimack River in Amesoury and Merrimac, MA, the terrain is'much rougher:

a jumble of hills and valleys eroded by drainages into the river.

These hills can be a significant impediment to sound propagation.

On the other hand, when their tops are accessiole, hills offer ideal siren locations because line-of-sight sound coverage can be provided to surrounding valleys.

.m The Merrimack River flows from west to east through the southern half of the EPZ.

In the coastal clain, its banks are snallow, and it is over a mile wide with tidal flats just east of the City of Newburyport.

Further upstream, it has formed an irregular valley 50-75 feet deep.

Sirens placed outsi~de this valley may not be neard within it and vice versa, so the siren system layout has special provisions for coverage within the valley.

Tne Piscataqua River, which is also the Maine-New Hampsnire State line, forms a portion of the northern boundary of the EPZ.

The Piscataqua drains Great Bay, also part of the nortnern limit of interest.

For the most part, the EPZ is heavily forested with deciduous trees:

second-growth oak.

The only exceptions are the beaches, uroan areas, tidal marshes, and occasional open fields.

The trunks of the trees in such forests can scatter and thus attenuate sound to some extent.

Tne effect is the same year-round, for the presence or ausence of foliage is of minor importance for siren tones, t

2.2 Climatology Coastal New Hampshire nas a typical, 4-season, nortnern temporate climate, modified somewnat Dy the proximity of the ocean.

"There are three distinct types of air masses that affect the site area:

a.

Cold, dry air originating in subarctic North America, b.

Warm, moist air from the Gulf of Mexico or the suotropical Atlantic, and c.

Cool, damp air moving in from the North Atlantic.

i _ _ _.

As the prevailing flow aloft over New Hampshire is usually offshore, the first two types of air masses influence the site area more tnan the third.

The

. climate of the site is thus continental in character, but with an important maritime influence."b1 The most important meteorological parameter affecting siren-sound coverage is wind direction because the vertical wind-speed gradient refracts sound waves.

In general, sound carries downwind to a much greater distance than. upwind.

~

Hence, a listener in the midst of a number of sirens is most likely to hear those upwind of his location.

Fall, winter and spring winds at the site prevail from the WNW and NW, with a typical speed of 9-11 mph at 30 feet.

In the summer, winds are more likely from the WSW and SW, and gentler:

4.5-7 mph.

In the fall and. spring, NE winds are not uncommon, and in the summer, gentle (7-9 mph) seabreezes from the SE occur during the daytime.[2]

The water-vapor content'of the atmosphere influences the I

extent to which sound is absorbed in air.

Absorbtion is

' greatest for cool, dry. air and least for hot, damp air.

The mean monthly relative humidity at Pease AFB, near the site, ranges from 64.7% in February to 74.4% in September.

U Daily minimum temperatures range from about 12 F in January U

U to 57 F in July; the daily maxima from.about 31 F to about 80 F.E#

U The vertical temperature gradient influences sound propagation in much the same way as the wind gradient, but to a lesser extent.

The vertical temperature gradient is related to atmospheric stability, as indicated in Table 2.1.

In coastal New England, C or 0 stability generally prevails.

However, very unstacle air (Class A) is not uncommon on blustery winter days, and very stable air (Class F) often occurs on clear, calm summer nights.

2.3 Demography Almost the entire Seabrook EPZ is populated:

.the only exception being the marsn and water areas along the coast and a i

few hilly areas inaccessible by road in the west.

Year-round residential concentrations exist in Hampton Center, about 3 1/2 miles nortn of the site; in Amesbury, 5 miles SW; in Newouryport, about 6-7 miles SSW; in Exeter, 8 miles NW; and in Portsmouth, 12 miles and more to the NNW.

during the summer, the 12 miles of ceaches from Newbury (Plum Island) on the south through Hampton on the north are densely populated by seasonal residents and visitors. _ _ _._ _ -_ _ __

Population distribution is important to the design of a public alerting system for the obvious reason that alerting coverage should be concentrated where people are concentrated.

Furthermore, the ambient background noise, which can interfere with people's ability to hear siren sounds, tends to increase with population density.

Tnis is because most of the background noise comes from motor vehicle traffic, and traffic tends to be neaviest in densely populated areas.

~

There have'oeen a number of studies of population distri-

-bution in the Seabrook EPZ.

The most recent summary of these is "A Compar'ison of 1980 Federal Census and FSAR Population Distribution Data for the Area Within Ten Miles of Seabrook Station," dated September 1983 and prepared for Yankee Atomic Electric Company by HMM Associates, Inc.

The figures shown in Table 2.2 are the highest of any of the estimates in that sum-mary document.

They include both permanent and seasonal residents.

Listed in Table 2.2 are the maximum resident populations by ring and sector, and the population densities per square mile.

The latter were obtained by dividing the populations by-the ring / sector areas noted at tne top of each column.

The guidance in Appendix 3 of NUREG-0654 indicates that, for sirens, a minimum coverage of 60 dB should be provided in areas having a population density of less than 2000 people per square mile.

For densities greater than 2000 people per square mile, the minimum coverage snould be 70 dB.

As indicated on Taole 2.2, only two areas exceed 2000 people / square mile:

Seabrook Beach and downtown Hampton.

In addition, Amesbury comes close to tnis threshold.

Because of the large area involved, the population data on Table 2.2 for the ring between 5 and 10 miles are not adequate for computing population densities.

Furthermore, the data do not extend beyond 10 miles, and thus do not include downtown Portsmouth.

For these reasons, and in consideration of the high summer traffic volumes to the beaches, a mucn more conservative design approach has been used for the areas in wnich siren coverage should be 70 dB or more.

The areas desig-nated for this higner coverage are illustrated on Figure 2.2.

2.4 Ambient Noise 2.4.1 Background G

The audibility of a siren sound depends upon the magnitude of other extraneous sounds at the listener's location while the siren is operating.

These other sounds, called the ambient oackground noise, come mostly from motor-venicle traffic; out numerous other sources are familiar (aircraft, barking dogs, cnildren at play, construction, etc.).

As these sources come and go, the ambient background noise fluctuates with time in a way that is unpredictacle, except in a statistical sense.

Siren audibility is cased upon the. minimum background noise that occurs during the time tne siren is operating.

Louder noises are unimportant, provided their duration is less than the duration of siren operation, Decause people tend to near during the quiet periods oetween interfering noises.

2.4.2 Design Basis A meaningful cnaracterization of the minimum ambient background noise over several hundred square miles, for all weather conditions, seasons of the year and times of the day, would De very difficult and costly to obtain.

Realizing this, FEM 4/NRC have provided a siren system design option which avoids background noise measurements.[5]

This option says, in effect, that the minimum ambient background noise in uroan areas (defined as areas with a population density of 2000 people per square mile or more) will generally oe less than 60 dB at some time during siren operation.

In other areas, FEMA /NRC indicates that it will generally be less than 50 dB.

3.3 Description of Sirens i

l i

j Of the 140 sirens in the system, 133 will oe new f

electronic sirens; 109 rated 125 d8(C) nominal, and 24 rated 115 dB(C) nominal.

The remaining seven are existing Federal l

Signal Type JT22 mecnanical' sirens recently installed by the l

City of Newburyport.

To accommodate the needs of the overall l

)

system, the City nas agreed to the relocation of three of these l

existing mecnanical sirens.

i The new electronic sirens are directional sirens of the l

1 1

rotating type capaole of four different tonal sounds plus a i

4 voice message.

One of these sounds will oe reserved for use in l

tne event of a Civil Defense dmergency, including a i

sufficiently serious accident at the Seaorook Station.

The 1

remaining three tonal sounds will oe availaole for other local j

purposes as selected by tne community.

L All of the new electronic sirens will De capable of broadcasting, acoustically, a voice message received over the f

radio-frequency (RF) siren-control channel.

Present plans call i

for the use of this capability along the public beaches to both

]

alert and notify beach users of a radiological emergency.

The i

19 t

1

sirens that will be employed for this purpose are RY-1, RY-3, RY-4, NH-1, HA-1, HA-2, HA-3, HA-4, SB-1, SB-5, SA-1, SA-2, SA-3, NP-1 and NB-1.

When producing tonal sounds, the new sirens will rotate or oscillate at a rate of 2-4 rpm.

When broadcasting voice messages, they will be fixed in desired directions and the message sent.

Tney will tnen be pointed in another direction and tne message repeated, etc., to obtain complete coverage.

The seven existing sirens in the City of Newouryport are omni-directional meenanical sirens, and are not capable of sending a voice message.

However, a new electronic siren to be installed on Plum Island in Newburyport (NP-1) will have voice capability, and people in downtown Newburyport will hear voice messages from electronic sirens in adjacent towns when the siren system is tested.

All of the new electronic sirens are battery operated, with a trickle charger permanently connected to the AC power distribution system.

In the event of complete loss of distrioution power, these sirens could operate in standoy mode for several weeks, or with full sound output for 1/2 hour.

The warning system relies predominently upon si ens with a nominal rating of 125 da(C) as observed 100 feet from the siren on tne axis of the. Torn (s)*.

These are tne largest electronic sirens commercially available.

Smaller 115 d8(C). sirens will be used at about 20% of the locations where terrain or other constraints make the use of the larger, more costly, sirens unnecessary.

The existing mechanical sirens in Newouryport have an advertised output of 113 dB(C).

Detailed specifications for tne sirens are given in the siren purchase specifications.

The actual advertised output is 124 d8(C) maximum.

See Taole 3.1.

3.4 Siren Coverage 3.4.1 Aj.ert Tone The area in which siren coverage is estimated to be 60 dB(C) or more is'shown on Figure 3.2.

The area covered by 70 dB(C) or more is shown on Figure 3.3 Both estimates are based upon circles having radii equal to the ranges in Table 3.1.

However, the' circles are truncated at hills that form the norizon as viewed from the siren.

The entire area within 10 miles of the plant is estimated to be covered by 60 dB(C) or more (Figure 3.2) except for a three lightly-populated regions in western Newburyport, southern West Newbury and southern Merrimac.

If tests of the system indicate that coverage of residences in those areas needs to be supplemented, then either-additional sirens or emergency-alerting radio receivers will be provided.

See Sections 3.6 and 3.10.

As shown on Figure 3.3, the design allows for coverage of 70 dB(C) or more on the beacnes and in essentially all populated areas within 5 miles of the plant.

All of the areas in Table 2.2 in which population exceeds 2,000 p/sq. mi. are covered by 70 dB(C) or more.

3.4.2 Voice It is assumed in this design that voice coverage is equal to the 70 dB(C) tonal coverage illustrated on Figure 3.3 The adequacy of voice coverage will De determined by the intelligibility of voice messages, as heard by observers some distance from the sirens.

This intelligibility will depend upon the message content, the speaker's voice.and his method of delivery.

Intelligibility can be maximized by following these guidelines:

o Use a trained, male speaker with a " neutral" accent (such as a skilled radio announcer).

o Prepare pre-recorded tape messages for various anticipated emergency action responses.

o Tne speaker should speak very slowly, with pauses oetween words.

o Keep the messages as brief and simple as possible, and repeat tnem.

o Employ simple words from common usage.

Use words that do not depend strongly on fricative or stop-consonent sounds to convey their meaning.

o Test the messages for intelligibility and refine them under simulated field conditions.

(This can be done in a suitably equipped audio laboratory.)

3.5 Siren Control All sirens will be controlled by radio signal.

In New Hampsnire, the primary state control point for a radiological emergency at Seabrook Station wil* be at the Rockingham police dispatch center in Brentwood.

In Massachusetts it will De at the State Police Troop A Headquarters in Framingham.

In addition, each of tne 23 cities and towns will have tneir own, totally independent control transmitters for all sirens within their borders.

See Tables 3.3 and 3.4 These town controls will serve as back-up for the State controls, and may also be used by tne towns to activate tne sirens for local purposes such as fire call-outs.

Each state will license one new HF f.requency for siren control, so the operation of the sirens will not add to the traffic on existing communication channels.

RF modulation for siren control will De either dual-tone multi-frequency (OTMF) tone sequences (like a touch-tone phone), or 32 bit frequency-snaft-keyed (FSK) sequences..Each State will have a map display / status coard showing tne control codes sent to sirens within that state.

1 3.6 Emergency Alerting Radio Receivers

)

Emergency alerting radio receivers will'be provided to 1

institutions within tne EPZ that would have to internally coordinate their response to a radiological emergency' at asaurook.

One hundred and fifty such institutions have been I

identified from local Emergency Plans and industry directories l

in New Hampshire and are listed on Table 3.5.

Similarly, l

{

eighty-four have been identified in Massachusetts, and are

[

4 i

i listed in Table 3.6.

j i

l Additional receivers will be purchased for possible l

I distribution to:

I i

j j

o Institutions similar to those listed in Tables 3'.5 and 3.6, but not yet identified.

i 1

o Homes with an occupant who is hearing impaired.

j o

Isolated residences wnere tests indicate that siren j

coverage must be supplemented, and where the provision of additional siren coverage would be uneconomical.

All emergency-alerting radio receivers will be activated l

by an EBS tone on a commercial broadcast station.

In New j

Hampshire, this will be WOKQ in Dover, New Hampshire, which is j

a 24-hour 50,000 watt FM station with coverage throughout the l

EPZ.

In Massachusetts the activation station will be WCGY, a l

50,000 watt FM station in t.awrence, MA.

Upon activation, the audio capability of the receiver will turn on, and emergency l

messages from the activating station will be audible.

Activation will also light a signal light on the receiver to

[

notify those unable to hear audible information.

3.7 Public Notification and Instructions via Emergency Broadcast The two state Civil Defense Organizations will assure that the dBS and other emergency broadcast stations are broadcasting emergency' messages and information to the public at the time that sirens are activated.

These emergency broadcast stations are WOKQ in Dover, New Hampshire, and WCGY in Lawrence, Massachusetts; the stations tnat will trigger the emergency alerting receivers in tne EPZ.

The EBS will be used in accordance with the respective state Emergency Broadcast System Manuals.

For the Seaurook Station EPZ, the Common Program Control Station in New Hampshire (CPCS 1), WTSN 1270 AM, will oe activated.

This CPCS 1 station will in turn activate all primary stations in the area.

Tne broadcast stations involved are:

I WTSN Dover, NH 1270 AM (CPCS 1) 2 WOKQ Dover, NH 97.5 FM (First Primary)

I WWNH Rochester, NH 930 AM (Primary)

WHEB Portsmouth, NH 750 AM; 100.3 FM (P rima ry)

WBBX Portsmouth, NH 1380 AM (Primary)

WKXR Exeter, NH 1540 AM; 107.1 FM (Primary)

WVNH Salem, NH 1110 AM (Primary)

WVNH Durham, NH 91.3 FM (Primary)

WPEA Exeter, NH 90.5 FM (Primary:

WENH Ourham, NH Channel 11 TV (Primary) 1 Emergency Power 2

24-Hour Capability.

Virtually all New Hampsnire stations witnin and acutting tne EPZ area nave been selected for inclusion in the emergency information network.

In this area each of the stations provide coverage of the entire New Hampshire portion of the EPZ.

Most of these stations are not operational on a 24-hour basis.

For such stations, advanced notice is needed before oroadcast can Degin.

For tnis reason, tne New Hampsnire E65 stations will be contacted by NHCOA at the ALCRT level if current reactor status indicates that a SITE AREA EMERCENCY might be declared.

Tnis would allow for the broadcast of messages at any time that the public alert system is to oe i

activated.

In Massachusetts, the activating emergency station, WCGY in Lawrence, is a 50,000 watt FM station on 93.7 MHz.

It will De activated oy Massachusetts Civil Defense prior to siren I

activation, as described in tne Massachusetts State Radiological Cmergency Plan.

l 3.8 Siren Activation Sequence l

In the event of a Site Area Emergency at the Seabrook Station, the respective State Civil Defense organization will notify their State control points to activate all sirens in each state.

Tne recommended activation sequence is as follows:

Winter:

3 minutes of tne designated emergency tone, immediately followed by a second 3 minutes of tone.

This process should be repeated after 10-15 minutes, if necessary.

Summer:

3 minutes of the emergency tone, immediately followed oy a second 3 minutes of the tone for sirens off the beaches. - -

Tne fifteen sirens to be used to alert and notify beach users snould broadcast voice messages during the second 3 minutes of activation.

These messages should be broadcast in each of the following directions:

N, NC, SE, S, SW, W,

and NW.

drief messages, repeated at least once, should be used.

Foreign-language messages may be broadcast in every direction immediately after the English language message.

This process should be repeated after 10 to 15 minutes.

3.9 Siren System Tests In accordance with the guidance in Appendix 3 of (40dCG-0654/FCM A dCP-1, the radio communication links for siren control will De tested at least once every two weeks.

Tne sirens will not ce sounded during these tests.

In addition, every siren will be sounded briefly at least once every three montns in order to verify that it is fully operational.

Finally, the entire siren system will be exercised fully at least once a year.

For tnese annual exercises, tne following sequence of operation is recommended, a.

A voice oroadcast of the message "This is a Test, This is a Test" in each of eight directions from all sirens.

b.

Three minutes of the Alert Tone on all sirens.

c.

Repeat of the voice message, a.,

on all strens.

d.

Hopeat of b.

e.

Repeat of a..

3.10 Provisions for Alerting System Improvements, if Required l

The design objective of tne public alerting system for the Seaurook EPZ nas been to provide coverage to essentially 100%

of the populated area of the dPZ, in accordance with Appendix 3 l

of NURCG-0654/F6MA REP-1.

The NRC recognizes that "this design objective does not, however, constitute a guarantee that early notification can ce provided for everyone with 1004 assurance l

or tnat tne system when tested under actual field conditions will meet the design oojective in all cases."

For th13 reason, system tests may indicate the need for corrective measures.

l dmergency-alerting radio receivers will be available for isolated residences in the event tnat siren coverage must be supplemented at their locations (see Section 3.6).

In tne unlikely event tnat testing reveals heavily-populated areas ere siren coverage needs to De supplemented, additional sirens will be installed.

The control system has the capability to operate additional sirens.

l l

l l.

4 ANALYSES OF SYSTEM PERFORMANCE 4.1 Activation Time The time to activate the sirens from a State control point, using an all-call coce, is about 0.4 seconds.

4.2 Siren Coverage of course, siren coverage varies with weather conditions.

It is useful, therefore, to exanine the coverage of tne CPZ under a variety of weather conditions.

This has oeen done using HMM Associate's SidCP computer program.

Tne computational algorithms for SIREP, and tneir origins in the technical literature, are descrioed in Appendix 0.

Four sets of meteorological conditions, listed in Taole 4.1, have oeen analyzed.

The first of these is representative of average summer daytime conditions, with a SC 0

wind, C stability, and 80 7 temperature.

The second condition modeled is tnat typical of summer nighttime.

Because of the light wind and strong temperature inversion, the coverage for this condition is greater than that for any of the other conditions.

The third condition is typical of a stormy spring or fall day:

a " northeaster".

The fourth condition modeled is that of a clear, windy (" blustery") winter day.

APPENDIX 0 SIdEP COMPUTATION PROCEDURES USED FOR THE ANALYSIS OF SIREN COVERAGE l

r p

I i

0-1

k SIREP COMPUTATION PROCEDURES For each of 16 compass bearings from a siren, SIREP tries a series of different ranges, starting as close to the siren as 150 feet and going out to a maximum of 20,000 feet.

The sound loss (attenuation) for each range is computed and subtracted from'tne siren level at 100 feet.

It is then determii6ad whether or not one of the desired levels of 60 da or 70 dB has been passed.

If so, the range to that level is placed at half I

the distance between the present range and the prior one.

Successive range steps are separated by a factor of 10 exp

((log 2)/10), which yields approximately a 1 dB step in j

attenuation.

SIREP computes and sums tne effects of the following sources of sound attenuation:

1 Spherical Divergence The siren is treated as a point source radiating energy into space, so the sound intensity decreases with the square of the distance from the source (" inverse square law").

This 1

creates a loss of 6 dB for each douoling of distance from the 100 ft. reference level.

See Ref. 1.

l Atmospheric Absorbtion Atmospheric absorbtion is computed using the equations of ANSI SI.26-1978 (Ref. 2).

5 i

Attenuation by Forests Attentuation througl forests is a strong function of

]

frequency, and depends upon the types of plants in the forest.

q Cxperimental data are quite variable (Ref. 3) and available tneory is not practical to apply in practice (Ref. 4).

l 0-2

, -. - m n

-n_

---c--,

In the frequency range at which most outdoor acoustic.

warning devices operate, forest attentuation results from scattering by tree trunks, and accumulates to a maximum within the first few hundred feet of forest.

Computations by SIREP are an adaptation of the attenuation rates proposed by Keast (Ref. 5), with the attenuation as a function of frequency established on the basis of the range of tree trunk diameters typical of the site (generally 6 in.-18 in. In the northeastern U.S.).

SIREP accumulates forest attenuation linearly in the first 250 feet of forest, up to a maximum of 10 dB (Ref. 6).

Ground Absorbtion Ground absorbtion results from the interference between the direct sound wave from the siren to the listener and other sound waves' reflected off the ground.

It is a detailed function of local geometry, ground impedance at the point (s) of re f ection, and sound frequency.

The theory (Chessel, Ref. 7) is well developed but impractical to apply except at very short ranges over uniform ground.

SIREP uses an empirical algorithm based upon the data of Parkin and Scholes (Refs. 8, 9) and other experimental data.

Ground absorbtion is accumulated linearly up to 1000 feet from the siren, and is fixed beyond that distance.

Ground absorption is a function of siren frequency.

Jt is ignored above 1000 Hz, and increases with decreasing frequency below 1000 Hz to a maximum of about 10 dB.

Wind Shadow To compute wind-shadow effects, SIREP assumes level ground and a horizontally uniform, vertically stratified atmosphere with constant wind direction, while temperature and wind speed vary with the logarithm of height.

The method of Nyborg and 0-3

Mintzer (Ref 10) is then applied to compute the distance to the snadow, if any, as a function of azimuth.

Within the shadow, attenuation is accumulated with range as reported oy Wiener and Keast (Ref. 11) to a maximum of 20 d8.

Built Up Areas SIREP assumes a fixed 10 d8 loss in ouilt-up areas to account for reflection and refraction oy buildings and loss of line of sight to the siren.

Inis empirical number is cased upon traffic-noise studies (Ref. 6).

It gradually disappears in upwind shadows.

l Hills and other Large darriers l

l SIRdP computes attenuation oehind hills and other large barriers by applying the method of Mackawa (Ref. 12).

Level ground is assumed except for the barrier.

When the user enters a barrier height that is celow siren level, such as could occur in sloping terrain, SIREP assumes the barrier is 5 feet above l

the siren elevation.

l Barrier attenuation is reduced downwind to allow for downward curvature of the sound paths.
