For many of us, our lives revolve around the sounds we hear. Sounds travel in waves and go through our ear canal, into the inner ear, then to eardrum and viola ? we hear noises. When noise levels are excessive, the delicate components of the inner ear can be damaged by the amplitude of the sound waves and vibrations that flow through it. Some symptoms of hearing loss include finding it hard to understand what others are saying in a group setting or when background noise is present and having trouble hearing voices in the higher frequency ranges.
Topics include how vibrations send sound, how noise levels can damage cilia, symptoms of hearing loss and what to do if you suspect hearing loss.
