Helmet Mounted Eave Ear Defenders

There is an existing issue with ear defenders of muffling all noise and not being able to hear calls by a fellow operative if a dangerous situation was to arise.
High levels of noise are related to all sorts of occupational health issues, wearing ear defenders all the time can add additional risks like not being able to hear anything.

The active ear defender has two microphones on the inside of the protective ear cups. These microphones measure the internal noise levels. The noise level data is wirelessly transmitted to peak to determine the percentage of noise exposure allowance remaining. Each speaker and microphone which is built in accurately and safely reproduce the sound from the surrounding worksite providing 360 degree situational awareness.

Noise levels are measured by four integrated microphones on each defender, this then wirelessly transmits the noise level data to an online software platform called Peak. Peak displays the noise on an interactive map of your worksite.

This has been adopted by a select group from each trade and positive feedback has been given from all involved.
