When it comes to learning linguistics, culture or just to balance our body, hearing is very important to our body. People who have a normal sense of hearing don’t really appreciate it until they loss it. People should therefore be aware of the causes of hearing loss as well as how hearing works.There are five section of the human body that are involved in the function of hearing. Although they may seem small, these five sections: the inner, middle and outer ear, the acoustic nerves, and the brain’s auditory processing centers, are the ones responsible for the hearing mechanism to work. It is a must that these five sections are working together for humans to have perfect hearing, once any one of these sections are damaged, losing the sense of hearing can be permanent.Do you want to learn more?

Sound vibrations from the environment are first collected by the outer ear that then funnels the collected vibration into the ear canal. The outer ear is also important in giving the brain information about where the sound is coming from and how far it is. Following the outer ear in an inch long passage called the ear canal, this is an inch long canal that is covered with hair and glands where we find earwax that prevent dust and other foreign matter to penetrate our ear.The middle ear then starts after the eardrum following the ear canal, and there are three important bones that can be found in the middle ear. Movements that matches the sound waves from the outer ear are created by these three bones that are called the hammer, anvil and stirrup. The movement made by these three bones are pushed from the middle ear to a membrane in the cochlea that is located in the inner ear.A crucial part of the inner ear is the cochlea which is sometimes compared to a snail because of how it looks like. The mechanical energy that pushed on the membrane that is produced by the matching movement can disrupt the fluid and in turn stimulates the hair cells. Different hair cells may respond to only certain frequencies therefore not all hair cells are stimulated by any one sound.The acoustic nerves then carries the signals from the hair cells to the brain in the form of nerve impulses. During this process, the central auditory system starts processing the information being carried to the brain. Sound is recognized by localizing it or identifying it source from recognizing patterns and differences from previous sound experience.
These are the important facts about how a person’s sense of hearing works. We can now better protect the sections of our hearing mechanism to be able avoid losing our sense of hearing. The following paragraphs will discuss some causes of hearing loss for better understanding as to how it can be prevented.Hearing loss can be the result of a lot of many different things and not just limited to birth defects or birth abnormality. A person commonly loses their hearing after being surrounded by noise and louse sounds regularly. Explosions can also temporarily cause hearing loss and in some other cases even permanent.
