The five senses are sight, sound, sight, taste, smell, and touch.  The first senses that we learn to use are smell and sound.  Newborns, for example, stop crying when their mother holds them because they recognize the smell.  It also has a bit to do with their bodies being in rhythm with each other. As a matter of fact, however,

So many aspects of the human biology have an expiration but that doesn’t mean we all age at the same rate or even in the same ways. What we do know is that we can expect to experience some changes or deterioration in abilities as we get along in year.

One common way that we age is in efficiency loss of our physical senses. Take hearing, for example:  many people experience hearing loss.  Indeed, it can be a normal part of aging, but there are other reasons people lose their hearing.

PRESBYCUSIS

This is the fancy, scientific term for “age-related hearing loss” and it is the term generally used to describe the gradual and equal hearing loss in both ears.  The condition typically involves damage to the inner ear that causes sensorineural hearing loss.

Sensorineural hearing loss is the term used to describe what happens when the hairs in the inner ear or the neural structures themselves malfunction in a way that hinders the delivery of chemicals that stimulate the auditory nerve (which translates vibrations into sounds).

Many things can contribute to presycusis—organ malfunction, health conditions, environmental toxins, etc—but the main trait here is that is an even loss of hearing that occurs over a long period of time.

NOISE-INDUCED HEARING LOSS

This is technically a specific type of sensorineural hearing loss. It is characterized by damage to the hair cells within the inner ear which normally vibrate in response to sound waves.  Too much sound (volume or otherwise) can overload these hair cells and they begin to malfunction.  To avoid this type of hearing loss try to avoid sounds at 85 decibels or above for prolonged periods (too many hours at a very loud concert, for example).

TINNITUS

Known better as “ringing in the ears” tinnitus is a type of sensorineural hearing loss in which you do not necessarily experience trouble hearing distinct sound but, instead, hear a constant ringing, humming, chirping, or buzzing.  Audiologie Centre-Ouest experts often suggest that neural hyperactivity—nerve overstimulation—can lead to this condition.
