What is Hearing?
Hearing is one of the traditional five senses… put simply hearing is the sense by which sound is perceived.
How do we hear?
Sound travels in invisible waves caused by a moving or vibrating object. The pinna of the ear funnels sound down the ear canal which eventually hits the eardrum.
This causes the eardrum to vibrate, which in turn causes the three tiny bones connecting the eardrum to the cochlea to carry the vibration onto the cochlea.
The vibrations continue through the cochlea to the tiny hair cells. These hair cells fire off electrical signals along the hearing nerve to the brain that perceives it as sound.
Hearing for life.
Hearing is such an important sense. Impaired hearing can significantly effect a person’s ability to communicate so hearing loss should not be ignored.
“The problems of deafness are deeper and more complex, if not more important, than those of blindnes. Deafness is a much worse misfortune. For it means the loss of the most vital stimulus — the sound of the voice that brings language, sets thoughts astir and keeps us in the intellectual company of man.” Helen Keller
