Hearing aids are electronic devices that amplify and modulate sound. Note that sounds are not just made louder through hearing aids. These devices adjust the sound they pick up, increasing the volume and tweaking the makeup of what would normally sound inaudible for a person with hearing loss. These miracle gadgets give people with hearing problems the opportunity to live normal lives instead of otherwise frustrating and depressing conditions.
Components of Hearing Aids
1. Microphone. A hearing aid may have one or more microphones. The microphone collects sound waves and transforms them to electrical impulses sent to the receiver.
2. Amplifier. The amplifier increases the strength of electrical impulses or digital signals.
3. Receiver. The receiver converts the electrical impulses back into sound waves and transmits them to the ear of the user.
4. Ear Mold or Sound Bone. This medium channels sound waves to the ear.
5. Battery. The battery provides the power supply.
6. Computer Chip. Computer chips are found in programmable hearing aids.
7. Internal Controls. These controls are set by your audiologist who aligns which frequencies to amplify, the amount of amplification provided and the saturation response or the loudest sound the hearing aid can produce.
8. External Controls. You can control the volume of transmitted sound waves through these switches.
9. Programs. There are different programs appropriate for several listening environments. One program can be for ordinary telephone conversations, another for face-to-face chats and yet another for noisy party banters. Some programs are switched automatically, adjusting to the environment, while other programs have to be changed manually.

Some Types of Hearing Aids
Since there are different degrees of hearing loss, different product designs have been developed to suit your needs. With these styles to choose from, you can select what would best improve your hearing.
The Behind-the-Ear (BTE) hearing aid has all components placed in one small case to be tucked behind the ear with a plastic ear mold fitting inside the ear. This type is suitable for all ages and various degrees of hearing loss.
The In-the-Ear (ITE) hearing aid is a very small device fitting completely in the outer ear. This style is not suitable for growing children.
The In-the-Canal (ITC) hearing aid is smaller than the ITE and fits in the ear canal. This is only appropriate for mild hearing loss. Completely-in-the-Canal (CIC) hearing aids are for mild to moderate hearing losses.
The Bone-Conduction hearing aid provides sound through a small vibrator powered by a hearing device attached to a headband. This is most appropriate when you can’t keep other hearing aids on your ear.
