a patient who signals that a tone was hard when no tone was presented is given what type of response?

A

False positive

19
Q

Why should diagnostic testing be conducted in a sound booth

A

To keep the background noise from making it look like a hearing loss

A

Interaural attenuation

27
Q

What is auditory neuropathy spectrum disorder?

A

normal outer hair cell function in cochlea, but the responses on the VIIIth nerve that carries electrical signals to the brain fail to occur in synchrony.
