B)trichromatic
C)gate-control
D)place

Question

Quizplus · Accepted Answer

The place theory of pitch discrimination states that different frequencies of sound waves produce maximal excitation of different locations along the basilar membrane in the inner ear. Therefore, Gabriel's ability to sense high-frequency sounds above 3,000 hertz is best explained by the place theory, as his auditory system is detecting which location on the basilar membrane is being stimulated by those higher frequency sound waves.
