SoundSign™ Noise Warning Sign

What is the SoundSign?

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.

Benefits at a glance: Lights up when a preset noise level is exceeded; Quick & simple to install; Trigger level from 40dB(A) to 114dB(A) for use in any environment; High intensity white LED technology for high visual impact and a long operating life; Use text and graphics to communicate specific noise level warnings; 4 standard designs to cover all applications.

In addition to the traditional Noise at Work style sign, the Sound Sign is also available with a range of other graphics and text which allows it to be used in environments where the noise levels may not reach those where hearing protection is required, but where there is still a need to warn or indicate excessive sound levels.

Ideal for Noisy Environments - Use the  SoundSign™ in noisy environments such as factories, workshops, pubs 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.

Ideal for Quiet Environments

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.

Installation & Use

Installation of a Sound Sign is very simple. Select the required trigger level and connect the 12v power supply to the unit. When the noise level measured by the microphone reaches this level, the sign will illuminate and show the warning.  The unit can also be set to keep the warning illuminated for up to 30 seconds after the level has fallen back below the trigger level. This removes the sudden on-off indication that traditional noise warning signs often produce and which can cause confusion as to when hearing protection should be worn. The SoundSign avoids these problems.

The sound level chosen for the trigger point can be set using either the simple level selection on the back of the unit or by using a calibrated Sound Level Meter to provide a reference measurement.

The brightness of the display can be adjusted making the SoundSign ideal for use in hospital and healthcare.

The SoundSign can be upgraded quickly and easily by adding the CR:203 USB Data Logger. This unit simply plugs into the SoundSign and can record noise levels for long periods of time. The Data Logger can be programmed to start recording at a specific time and date and run, for example, over an 8 hour shift.

The Data Logger can be plugged directly into a PC and the software supplied will display a graph of the recorded noise levels, allow the information to be printed, exported and annotated for reference.
