A single of the most essential parts of our body may be the ear which helps us to detect and also hear sound. Audition is the sense of sound's scientific name. Sound could be considered as that form of energy, which can travel through other forms of matter within the form of "waves of pressure"; it also helps us as important means of communication.
The sound is modulated into various types that we differentiate as languages and use the same to communicate what we believe. The ear is one of the five sense organs, with the primary role of recognizing and sensing sound. Using the assist of our central nervous system, we hear it and realize it. The sound waves pass through the nerve cells within the nervous system that's responsible for the auditory function and reaches the brain.
Our ear's outer parts are structured in a way that they collect maximum sound from your environment. The sound waves which are collected by the outer portion is then amplified by the middle portion and then forwarded from the air medium to liquid medium. The transformation of medium from air to liquid occurs as they sound waves travel with the ear.
The densest bone in our body may be the temporal bone that is present in the inner portion of the ear. Liquid with sensory epithelium and hair cells are present within the empty inner channels of our ear.
The sound waves which move with the fluid epithelium push the protein filaments; the hair cells fires when the filaments bend over are sufficient. This is the process, by which sound waves are converted into nerve impulse. Cerebral cortex is that part from the brain whose function is to interpret senses that's being converted into impulse.
Unknowingly or knowingly we tend to hurt our ears, by listening to sounds beyond the hearing capacity of our ears. This high volume sounds will cause damage to our ears as they are very sensitive in nature. Individuals should be aware of the seam limits that our ears can accommodate and should make certain that, we are nicely within the limit. In fact hearing disability has been increasing in the recent past, as people often hear amplified sounds and love to do it.
Ear drums are really first damaged, when a prolonged exposure to sounds that's nicely above the hearable limit. This in turn makes it hard for them to hear sounds, and eventually would lead to a hearing disability thereby making them deaf; and certainly that is not something one would wish to happen. This can be prevented, by avoiding higher volume sounds and also maintaining the sound at a degree that is very gentle to our ears. An easy check on the degree of sound could be kept, to ensure that we don't exceed it. Ears are really sensitive and that is why factories provide their workers with ear covers/ear plugs, to protect their ears from your high volume sounds produced by the machines that are planted there.
