The Noise Activated Warning Sign

SoundSign™ is a highly visible noise activated warning sign that has been designed for use in environments where there is a need to clearly warn or indicate when a preset noise level is reached.

Use the SoundSign™ in noisy environments such as factories, workshops, bars, and nightclubs to warn when noise levels become too high and indicate when hearing protection must be worn. For example, the “Hearing Protection Must Be Worn” version can be used to reinforce the need to wear hearing protection when noise levels reach a set level. A noise survey may have indicated that the levels will exceed 90dB(A) when certain processes occur but this may happen at random intervals throughout the day. The wearing of hearing protection may not required at all times and so the use of the SoundSign will inform employees when it is required and when it can be safety removed.

You may also use SoundSign™ in quiet locations such as schools, hospitals and libraries to indicate when noise levels must be kept down. Set the SoundSign to trigger at a much lower level, 50dB(A) for example, to ensure that the noise levels in a hospital ward stay within acceptable levels. There is no need to use hearing protection but the use of a clear warning sign can be very effective in controlling and managing noise levels.
