Sirens

Sirens, sometimes known as a sounder, are used to attract interest and to present warning, particularly where an immediate response is needed. The sound has to be surely audible and identifiable to the human in the meant signalling area, and these are regularly used to complement a visible sign. Audible signalling is mainly useful in conditions in which sight maybe a problem, like in a bright sunlight or for the visually impaired. To alert a person, it is recommended that a sounder or siren reaches at between 5 and 15 dB(A) louder than the background noise of the given area. Frequency should also be between 300 and 3000 Hz.

Things to consider when selecting a siren:
• The sound pressure level achieved, quoted as decibel or dB(A).
• The frequency quoted in Hz.
• The distance it must be audible over.
• The background noise of the area it will be installed in.
• The sounds any machinery in the area makes to ensure the tone of the sounder or siren does not sound similar.
• The duration of each use - quick bursts or prolonged use.
To enable easy comparison, the dB(A) stated for a sounder or siren is usually measured at a distance of 1m. When the distance is doubled the dB(A) to drop by 6. This is why it is important to know not only the dB(A) the sounder or siren is capable of, but also the distance away from the intended signalling area it will be placed.
It is also worth noting that louder is always best. It is strongly recommended that the sounder or siren is sized to be within 5 to 15 dB(A) above the ambient noise level. Whilst the recommendation is that we aim for a level between 5 and 15 dB(A) above ambient, studies have found that it is possible to distinguish a sound that is up to 10 dB below ambient as long as there is sufficient frequency differential.
We offer a range of sirens which can be used in business departments such as Fire, Industrial, Emergency and Warning Systems.
