We experience sound in our environment every day, such as the sounds from television and radio, people conversing, and traffic. Normally, we hear these sounds at safe levels that do not affect our hearing.
However, when we are exposed to harmful noise – sounds that are too loud or loud sounds that last a long time – sensitive structures in our inner ear can be damaged, causing noise-induced hearing loss. These sensitive structures, called hair cells, are small sensory cells that convert sound energy into electrical signals that travel to the brain. Once damaged, our hair cells cannot grow back.

What is unique about the filters H.A.S.S. Industrial uses?

They are adjustable, which means they can be set for various noise areas. If hearing is over-protected, the user will struggle to hear instructions or follow a conversation. In the case of under-protection, the user could suffer from a noise-induced hearing loss over the long-term. It is therefore important that a balance be achieved between attenuation and communication.
