Problem a person has severe hearing loss that reduces the, Ask an Expert

Academics

Problem: A person has severe hearing loss that reduces the intensity in his inner ear by 39.1 dB. To compensate, a hearing aid can amplify the sound pressure amplitude by a certain factor to bring the intensity level back to the value for a healthy ear.

Part A: What amplification factor is needed for this person?

Please use great detail in explaining the solution. Thanks.
