subject: The Causes Of Hearing Loss [print this page]

Hearing is considered to be the most significant

of all senses present in the human body. In view

of the fact that, through the help of a persons

ability in terms of hearing, he or she can be able

to learn various cultures, languages and others.

Once a person loss his sense of hearing this would

show the way for the subsequent change in their

means of living. With this, a person should at

least be knowledgeable on what are the causes of

hearing loss.

The first step for hearing mechanism is the

collection for sound vibrations from the

environment. In addition, the outer ears are

responsible for gathering the information on where

the sounds forthcoming and the distance of sounds

actually are. It should be prevented from the

entrance of dusts and other foreign matters inside

the ears since it can be the reason for the

defective hearing mechanism.

After that, the next step is for the acoustic

nerve to transmit the signals renewed to nerve

impulses coming from the tiny hair cells going to

the brain. These impulses are being processed even

earlier than the moment it reaches the brain via

central auditory system. In addition, a time stamp

is then positioned on the sound at what time the

brain tries to make a distinction on it and

localizes it from other sounds.

The occurrence of these things allows a person to

have the sense of hearing as well as the ability

to understand the sounds being heard. In order to

keep away from losing one of the most vital senses

in our body, we should be equipped with knowledge

regarding on the protection of ones senses

specifically the sense of hearing and also the

causes of hearing loss and how this can be

avoided. Loss of hearing is not only caused by

birth defects but also it is caused by other small

or either large physical and other physical

things. For instance, a person can lose his or her

sense of hearing by direct exposure to too much

noise pollution. And also, it can be caused by

other noises even if the length of sound is short

-lived, for example caused by explosions.

Additionally, even viruses or bacteria can cause

destruction on the bodys hearing processes. Yet,

the presence of chemicals in herbicides or either

pesticides can as well cause a person to lose the

hearing mechanism.
