Abstract

The concept of a reusable earplug for hearing protection of industrial workers in Canada and its performance to sound exposure was presented. The earplug was developed that was custom-fitted using silicon injection and field tested for attenuation on the worker. The ability to hear speech and warning signals could be partially addressed by adapting the earplug attenuation to the actual noise exposure of the worker. The proposed adaptation was based on a set of acoustic filters that could be placed into the earplug's sound-bore resulting in a protected exposure level between 70 to 85 dBA.
