Answer:

Hmm.

Step-by-step explanation:

A hearing aid amplifies sound waves.

'A hearing aid is a small electronic device that you wear in or behind your ear. It makes some sounds louder so that a person with hearing loss can listen, communicate, and participate more fully in daily activities. A hearing aid can help people hear more in both quiet and noisy situations.'
