Providing a sound warning

A recent customer for Cirrus Research was Sheffield Forgemasters International which initially ordered six of the SoundSigns; this order was quickly doubled to 12 as the health and safety team realised the many benefits the technology brought to its metal forging production floor.

SoundSigns were installed in the heavy machine shop, which houses milling and boring machines of various sizes and capacities, to monitor the noise levels of the machinery, letting SFIL reduce the mandatory noise area.

The SoundSigns were pre-set at levels 80-85dB – the action levels stipulated under Noise at Work legislation. These warn employees of any noise level breaches and instruct them to wear hearing protection. Once the noise levels dissipate the signs automatically switch off.

The white LED technology allows for a high visual impact when noise levels are breached, as well as a long operating life. Signs are quick and simple to install with no training required. The Trigger level from 40 to 114dB(A) can be used in any environment. Signs uses both text and graphics to communicate specific noise level warnings.
