4. The information in this section provides guidelines to aid the user in the selection of an installation site that makes the best possible use of the siren WARNING The output levels of the Model 2 siren are capable of causing permanent hearing damage To prevent excessive exposure carefully plan placement of siren and post warnings If the siren is being installed as part of a Civil Defense Warning system always follow Federal Emergency Management Agency FEMA recommendations Careful consideration of the factors affecting the propagation of sound from the siren and the response of the human ear to the sound will optimize the ability of the siren to effectively warn the community The reduction of signal intensity as the distance from the siren increases and the minimum desired signal level at the fringe of the area to be covered are important considerations when choosing a siren installation site As the distance from the siren increases sound level losses accumulate These losses are a result of weather conditions the terrain and obstructions in the sound path the pitch of the sound and the height of the siren Optimum sound propagation conditions exist when there are no obstructions in the sound path the terrain is flat and the air is calm Under these conditions each time the distance from the siren is doubled the sound level decreases by approximately 8dB For example the sound level 100 feet 30 5m from a Model 2 is 1

9. 02dB at 200 feet 61m the sound level drops to 94dB at 400 feet 122m the sound level drops to 86dB etc This is referred to as the loss per distance doubled A loss per distance doubled of 8dB is seldom experienced This is because buildings and other obstructions are frequently present in the sound path In addition the atmosphere is rarely calm and the terrain may not be flat As a result a typical loss per distance doubled in residential areas may be 10dB and as high as 12dB in areas having tall buildings Experience indicates that an individual with normal hearing will probably hear a warning signal whose intensity is at least as high as the ambient noise level Experience has also shown that the ambient noise level in industrial districts is typically 90dB Therefore for a person to hear a warning signal in an industrial area the sound level intensity of that signal must also be approximately 90dB In this situation any point receiving a signal having less than 90dB intensity is considered to be outside the effective range of the siren In business districts an ambient noise level of 80dB is common and in residential areas 70dB of ambient noise is typical Assuming a 10dB loss per distance doubled and a 70dB minimum sound level the effective range of a Model 2 is approximately 910 feet 278m Wind speed and direction often affect the propagation of sound from the siren Consequently the direction of the prevailing wind ma
