Intelligent hearing protection and functional enablers

Intelligent hearing protection and functional enablers


When a helicopter lands on an offshore platform, the noise level is so extreme that the number of landings per day is sometimes limited. With landings reaching upwards of 115 decibels, dual protection is not enough to protect these workers.

While on the helideck, platform workers use headsets with boom microphones connected to radios to communicate. These headsets do not provide adequate protection from the high helicopter noise, making it difficult for helideck workers to hear incoming communication. At the same time, the high levels of ambient noise can also compromise speech intelligibility, hindering communication and, ultimately, put worker and others on the platform at additional risk in the event of an emergency.
Such challenges stunt the ability of a crew to receive supplies and machinery for during a mandated turn-around, and can also limit the turnover of work crew shifts on a platform.
Companies that face such extreme situations use intelligent hearing protection as an integrated hearing protection and communication solution. Not only is the protection of each offshore platform worker validated and continuously monitored, they can clearly communication through radios. In addition, through personal sound exposure monitoring for noise dose, these workers can work for longer hours under high noise conditions. This could mean a faster platform turn-around or more helicopter landings per day.
