The site has been trialling the use of the Eave Noise Reduction Ear Defenders. A common issue with standard ear defenders is that they are taken off when operatives want to communicate with each other. This then puts the operatives at risk of permanent damage to their hearing.
These ear defenders appear to solve this issue. They contain microphones and speakers, similar to an audio headset. This allows the operatives wearing them to communicate via Bluetooth.They also filter out background noise whilst accentuating human voices, allowing each operative to be heard clearly.
The product also includes Bluetooth beacons which are placed around the site. This enables noise mapping and provides data of where and when exposure is observed thereby allowing for interventions.
