How Our Hearing Works

The improved ability to hear has a tremendous impact on the quality of life for both those with hearing loss and their families. Having a good understanding of how your hearing works and then knowing your options for the best help available through today's advanced hearing aid technology will help you make the right choice in amplification - and to use your new hearing instruments to their fullest potential.

As sound passes through each ear, it sets off a chain reaction that could be compared to the toppling of a row of dominoes. First, the outer ear collects pressure (or sound) waves and funnels them through the ear canal. These vibrations strike the eardrum, then the delicate bones of the middle ear conduct the vibrations to the fluid in the inner ear. This stimulates the tiny nerve endings, called hair cells, which transform the vibrations into electro-chemical impulses. The impulses travel to the brain where they are understood as sounds you recognize.
