Hearing aidsWhat is a hearing aid?A hearing aid is a small electronic device that must be worn in or behind the ear depending on where the damage was caused. The fact that people suffer from hearing loss is a huge problem, without hearing loss you are at a disadvantage in most lifestyles, but with hearing aids this problem is solved. They are made to help people hear by making sound louder so they can listen, communicate and participate in everyday activities. The hearing aid can be used in both noisy and quiet situations. A hearing aid can be modified to help different cases of hearing loss. A hearing aid is made up of four main parts:Microphone: The microphone picks up sound waves and converts them into electrical energy. Then he delivers it to the amplifier. Amplifier: The amplifier is used to increase the amount of electrical energy, which transfers the amplified energy to the speaker. Speaker: The speaker uses amplified energy to produce an augmented sound so that the person who is deaf can hear. Battery: The battery provides energy to the hearing aid, it is variable in size, has a positive side and a negative and the normal life of one of the batteries is 1-4 weeks.(Beltone, 2014)How Human Hearing Works The human ear is made up of three different parts, the inner ear, the middle ear and the external ear, each different part of the ear contributes a specific reason to the process of detecting and interpreting sound waves. The outer ears are used to collect, channel, and collect sound waves to divert them to the middle ears. The middle ear is used to transform the energy of sound waves into internal vibrations of the structure of the bones of the middle ear; it eventually converts these vibrations into the form of...... middle of paper ......useHearing loss has been a problem for hundreds of years but thanks to the invention of the hearing aid it has made the life of the it is much easier for deaf people to interact with deaf people. Although the hearing aid is very expensive, the research and creation of the actual product is helping people with this disability and making them smaller so that they are harder to see and do not embarrass hearing aid users. I believe that the hearing aid is a very successful technological product and that it has almost completely eliminated the problem of hearing loss because anyone who wears one can hear practically perfectly, but the fact is that not everyone can afford a hearing aid. If science looked more into hearing aids, it could create a hearing aid that is completely internal, then integrated into the person's ear.
