Disadvantages Of Deafness

Nowadays, many people are losing their hearing. Well, There are several factors leading to deafness or hearing loss, deafness is generally caused either by one of the parts of the ear being damaged, ruptured, or a part not functioning properly, an infection (virus), disease, or a damage in one of the nerves in our ear, some of these damages might be temporary and others permanent (Figure 3). “Deafness is the incapability to hear a certain sound wave, or problems in transmitting the vibrations into a message to our brain through the auditory nerve, or having a thorough lack in the sense of hearing. As a part from this, people with limited hearing aren’t considered deaf. Deafness is divided into three main types as in the

Some of these tips might be, lowering the periods of time our ears are exposed to loud sounds and music and especially in building areas, which can lead to damaging our hair cells in the inner ear. This can be solved by wearing ear plugs (figure 4), which can advantage us in, making loud sounds lower between (15-30 decibels) or wearing ear defenders (figure 5) .As well as, preventing ourselves from shouting which can cause a damage or a rupture in one of the parts in the ear, and decreasing the time in which our ears are exposed to loud sound that are either (105 decibels) or more to no more than 15 minutes

At first, loud sound waves moves to the ear mold after passing by the ear hook (which carries the hearing aid on the ear, and it’s a plastic piece).The ear mold is made from mold. (The rest of the parts are located in the case of the aid) These parts interact, in which the hearing aid (Microphone) gathers the sound wave from the air, and translates them into electrical signals. The, amplifier increases the strength of those electrical signals. After that, the sound waves are transmitted into vibrations and directly sent to the ear by the receiver and delivered to the brain. As a part from this, the hearing aid doesn’t work without the battery which gives it power to work, the volume control which differs according to each person’s situation, and the On/Off switch which turns it on and off. (Figure 6) This technology has its own advantages and disadvantages, the advantages and disadvantages of the (BTE) aid is in the following, advantages, (socially) the way it is used in is easy and simple, and can be cleaned and maintained easily, (psychologically) all its parts function properly and eventually can deliver a certain sound wave to the brain, which raise the person’s confidence (understand things faster) instead of using sign language. As for its disadvantages from sides of (economically) its price is expensive (around $50-120).Therefore, it is not affordable in poor counties, (socially and psychologically) its size
