A hearing aid is a tiny electronic device worn in or behind an individual’s ear. Its purpose is to amplify sound so that a person who has a hearing loss can hear and participate fully in everyday activities.
Hearing aid allows a person to hear and understand conversations in both quiet and noisy places.
A hearing aid is composed of three parts that include the microphone, speaker and the amplifier. The gadget receives sound waves through the microphone, which changes the sound waves into electrical signals. These signals are then sent to the amplifier. The amplifier improves the intensity of the signals and then transmits them to the ear through the speaker.
The hearing aids are useful in enhancing the hearing and speech recognition of individuals who are affected by damaged sensory cells. This kind of hearing loss is referred to as sensorineural hearing loss. The hearing loss related to sensory cells mostly affects the aging individuals.
There are numerous types of hearing aids:
- Behind–the-ear
Behind the ear hearing aid attaches and holds at the top of a person’s ear. A unique tube usually connects the hearing aid to an earpiece known as the ear mold, which fits well into the ear canal. This type of device is suitable for people of all ages, and it provides additional amplification than other models of hearing aids.
- In-the-ear
In-the-ear hearing aid is manufactured in two models. One style fills most of the bowl-shaped outer ear. The other design fills only the lower part of the ear. Both types are good for people who suffer from moderate to severe hearing loss.
- Canal aids
Canal aids fit well into the ear canal. They are prepared in two varieties. The in-the-canal (ITC) aid fits precisely into an individual’s ear canal. A completely-in-canal (CIC) is almost hidden in the ear canal.
A hearing aid is not supposed to restore your normal hearing. However, with practice, a hearing aid will increase sound awareness.
Because hearing aids are used on a regular basis, you should choose a type that is comfortable in your ears. Other factors to consider when choosing a hearing aid include the cost of repair, upgrade opportunities, maintenance and the reputation of the manufacturing company.
Before purchase, you should familiarize yourself with the device in the presence of an audiologist. Audiologists are professionals who are trained to diagnose and treat hearing problems. You should learn how to program and adjust the hearing aid’s volume before carrying it home.
