Combination Alarm Horn Sounders and Beacons/Lights

E2S AL100X

E2S produces a diverse selection of alarm horns or sounders suitable for various applications. The effectiveness of any audible signaling device relies on factors such as the size and/or distance of the area to be covered, background noise, and the pattern and frequency of the tone.

The loudness of a sound diminishes as the listener moves farther from the sound source, primarily due to "divergence." The intensity decreases because the energy spreads across a larger area, following an inverse square law. This means that for each doubling of the distance from the source, the sound intensity decreases by 6dB. For example, if an alarm is rated at 106dBA, it will reach twice the distance compared to a sounder rated at 100dB(A). If a sounder is initially rated at 100dB(A) at 1 meter, it would be 94dB(A) at 2 meters, 88dB(A) at 4 meters, and so forth.
