A hearing aid, also known as a CIC, is a tiny device specifically designed to enhance hearing for an individual with hearing impairment. Hearing aids are generally classified as therapeutic devices in most countries and subsequently regulated by the various regulations set out by the Food and Drugs Administration. There are three types of hearing aids: Behind-the-ear; in the canal; and in the ear alone. Although several people are uncomfortable with certain types of hearing aids, many individuals find that wearing an aid can improve their quality of life.
Styles of hearing Aids.
There are many different styles of hearing aids, which will work best for different people. The size of the person’s head and ear canal is critical in determining the type of hearing aid that will work best. For example, those who wear Behind-the Ear hearing aids will need to wear a hearing aid behind the ear, so they can still hear things above their heads. The behind-the-ear style of hearing aids can also work best if a person has large ears, but because the aid is behind the ear it does not obstruct sounds that are already in the ears.
BTE Hearing Aids.
BTE hearing aids are extremely popular and are the most common type of hearing aids. These hearing aids work by allowing the wearer to connect the base unit to the outer part of the ear. To adjust the tone, you simply have to turn the control knob while you look into the device. BTE hearing aids have a number of different styles and models, including the behind-the-ear and in the canal models. BTE hearing aids are often more expensive than in the other two types of hearing aids.
A good ear, nose and throat specialist can make an audiologist recommendation for a hearing aid based on your needs. An audiologist is an expert in this field. You will be given a variety of exams to determine what kind of hearing loss you have. You will also be given a prescription for an appropriate audiometry test. The audiologist will examine your ear canal, the outer parts of your ear and the muscles around the ear. It is important to remember that no two people suffer from the same type of hearing loss.
Once the audiologist has determined what type of hearing test you need him or she will help you select the right one for your needs. The selection process can be difficult if you have never owned a hearing aid before, especially if you are trying to shop for a device that is different than the one that your family and friends have used. If you have never worn an aid before, your audiologist may suggest that you wear a trial pair to observe your listening environments before making a final decision. The audiologist will adjust the aid to help you hear better.
The aid you will receive will also include additional devices that will allow you to make sounds louder. The basic unit will consist of a microphone, amplifier and directional speaker. The microphone will capture your surrounding environment, including the noise level, and convert the sound into digital information that your amplifier will then convert back to the original sound. The directional speaker will increase the volume of the sound produced and allow you to adjust the level to your desired level. The final piece of equipment in your aid will be a sound generator that captures your own natural sound and combines it with the outside noises to create a new, more realistic sound.
Different types of Microphone.
There are several different types of microphone options for those who need assistance with their hearing. These different types of microphone will provide a higher or lower quality recording for your listening sessions. The better the sound quality of the microphone, the clearer and louder the audio will be. Most commonly, microphones use capacitors to capture electrical signals. Capacitors allow electrical signals to capture the energy from the sound waves and convert them into electrical signals that the speaker and amplifier can then transmit clearly.
The most sophisticated microphones available in this technological era feature what is called phase reversal. This technology allows the microphone to take a lower tone and then filter out high frequency noise that has been introduced during playback. The resulting sound can then be amplified to produce a much higher quality sound. With this type of microphone, the resulting audio is cleaner and a lot more enjoyable to listen to custom suits.
