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 person's 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 one's 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 body's hearing processes. Yet, the presence of chemicals in herbicides or either pesticides can as well cause a person to lose the hearing mechanism.
