Industrial Hearing Conservation programs have become common in America's workplaces, due to stringent, government-imposed noise exposure limits. Both disposable and custom-molded hearing protectors are widely used in industry and construction, as are head-worn earmuff devices.
An effective defense against very loud noise is Microsonic's Sound Defenders, molded from ear impressions made by an industrial hygienist, audiologist or hearing aid dispenser. These hearing protection devices are molded in Synth-A-Flex II vinyl or in M-2000 silicone. The solid construction of the material provides a significant degree of attenuation.???
