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 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.
