Quizplus · Accepted Answer

The discovery that high-frequency sounds trigger large vibrations near the beginning of the basilar membrane supports the place theory. Place theory proposes that different frequencies of sound waves activate different places on the basilar membrane, which is a thin strip of tissue within the cochlea of the inner ear. High-frequency sounds cause vibrations near the beginning of the basilar membrane, while low-frequency sounds cause vibrations near the end, according to the place theory.
