Physio to the Brain

We don't really hear with our ears - we hear with our brain:

The way we hear sound is that it travels into the ear canal causing the eardrum to vibrate.  Attached to the eardrum are three little bones called "ossicles" (hammer, anvil and stirrup) which mechanically moves the sound from the ear drum to the cochlea or "hearing nerve".  The cochlea is where the auditory nerve begins.  As the eardrum moves back and forth vibrating from sound you just heard, the ossicles transfer the sound into the cochlea.  It is here that the auditory nerves "fire",  sending the message through the brainstem to the brain.  Again, we don’t really hear in our ears; we hear in our brain.

The auditory nerve is like a piano - if you were to unroll the cochlea which is the shape of a "snail", the analogy is that it would look like a piano with all the white and black keys.  We have a nerve for every pitch or tone. It is these nerves that are typically damaged with hearing loss.  Either noise has caused damage to these nerves or as we age - our hearing nerves will deteriorate.

The brain is responsible to interpret the sounds we hear - the sounds that are transferred from the ear to the brain.  It is here that we are able to make sense of what we have heard.  If a patient experiences a hearing loss and the hearing loss remains untreated for several years, the brain will "forget what to do with the information".  This is the cognitive part - remember, we hear with our brain.

Technology is an amazing thing - all hearing aids by todays standards have advanced processors with wireless capabilities.  These hearing aids, if properly progammed to the patients hearing loss will provide audibility, but may not resolve susceptibility to noise, or degradation of cognitive skills associated with aging.  With Carolyn and her staff's expertise, patients will be properly fit with appropriate amplification based on their hearing loss as well as cognitive abilities.  From this point, patients will be educated and counselled as to how to "relearn" to hear sound, how to "hear in noise".  Some patient require additional therapy.  This is an extremely important part of the process and is why individuals presenting similar hearing patterns frequently report a wide range of satisfaction and benefit from amplification.
