People with hearing loss have reduced dynamic ranges of hearing. Therefore, hearing aids change the amount of gain they apply based on the sound pressure level of the input sound to the hearing aid. What is this called?

People with single-sided deafness are candidates for cochlear implants. 

When a person has sensorineural hearing loss, their thresholds decrease but their dynamic range remains the same.

Directional microphones and digital noise reduction are designed to improve speech perception in noise.

Asymmetrical hearing loss is more common in children than adults.

The most common cause of genetic hearing loss is: 

Based on the 1/2 gain rule, how much gain (in dB) would you apply for this listeners in the right ear at 500 Hz?

Bilateral atresia causes sensorineural hearing loss.

The electrode from a cochlear implant is inserted into the:

A disorder present at birth is called , whereas a condition that someone develops later in life is called .
