Noise activated warning sign
22 July 2014
Cirrus Research has supplied Sheffield Forgemasters International Ltd (SFIL) with 12 of its SoundSigns – a highly visible noise activated warning sign designed for environments where there is a need to clearly warn when a preset noise level is reached.
The SoundSigns were installed in the Heavy Machine shop to monitor the noise levels of the machinery and so letting SFIL reduce the mandatory noise area.
To mitigate the risk and exposure to excessive noise levels, the SoundSigns were pre-set at levels 80-85dBs - the action levels stipulated under Noise at Work legislation. These warn employees of any noise level breaches and instruct them to wear hearing protection as a result. Once the noise levels dissipate the signs automatically switch off.
