What is a hearing aid?
A hearing aid is a battery-operated, electronic device, which amplifies and changes sound to allow improved communication. Hearing aids receive sound through a microphone, which then convert the sound waves to electrical signals. The amplifier increases the intensity of signals and then sends the sound to ear with the help of a speaker.
What are the different kinds of hearing aids?
Several types of hearing aids are available in the market. Each type provides its own advantages depending upon its size, design and level of amplification. Before purchasing any hearing aid, you should confirm that it would work for you. Most manufacturing companies provide a two-month trial period during which you can return your hearing aid.
Four types of hearing aids are given below for people with hearing impairment:
(ITE) In-the-Ear hearing aids: This type of a hearing aid fits completely in the outer ear and is useful for mild to severe hearing impairment. The case of the hearing aid is made of hard plastic. In-The-Ear hearing aids can hold telecoil (added technical mechanisms that help hearing aid to improve sound intensity during telephone calls.) ITE hearing aids can give poor feedback if they are damaged by ear drainage or earwax. ITE hearing aids are generally not used by children, as the casings are needed to be replaced as ears grow.
(BTE) Behind-the-Ear hearing aids are worn behind the ear and are connected to a plastic earmold that fits inside the outer ear. The components of the hearing aid are held in a case behind the ear. Sound travels through the earmold into the ear. These types of hearing aids are used by people of all age group. Poor earmold fitting can cause a whistle sound production or formation of earwax or fluid.
Canal hearing aids are available in two sizes. Canal hearing aids fit into the ear canal. A (CIC) or Completely-in-Canal hearing aid is mostly hidden in the ear canal and is used in the cases of mild to severe hearing impairment. CIC hearing aids are very small in size and that's why it is not possible to attach additional devices like telecoil. These hearing aids can also be damaged by ear drainage or earwax and are not recommended for children.
Body hearing aids are also available in the market. They are big in size and mostly used when other hearing aids are not useful.
On some special occasions discount hearing aids are also available in market. You can buy discount hearing aids ranging from digital hearing aids to the basic behind the ear hearing aids. Some online sellers provide a larger selection of discount hearing aids at a more affordable price. Many companies like Songbird Hearing USA offer hearing aids for sale.
Make a detailed study before you place an order for a discount hearing aid.
