Hearing starts with the outer ear. When a sound is made outside the outer ear, the sound waves, or vibrations, travel down the external auditory canal and strike the eardrum (tympanic membrane). The eardrum vibrates. The vibrations are then passed to 3 tiny bones in the middle ear called the ossicles.

What is a basic hearing aid?

The amplifier increases the power of the signals and then sends them to the ear through a speaker.

How bad does your hearing have to be to get a hearing aid?

What is the difference between an amplifier and a hearing aid?
Hearing aids perform a complex purpose that depends on the wearer, whereas amplifiers boost all sound. Hearing aids are usually professionally fitted and fine-tuned to the wearer and help mitigate hearing loss by boosting certain frequencies. Amplifiers simply make things louder, regardless of the frequency or volume.
Is it OK to wear just one hearing aid?
If you have normal hearing in one ear, and mild hearing loss in the other, you’re probably fine to just wear one hearing aid—just remember to get regular hearing tests to make sure your “good ear” is still hearing well.
