Basilar Membrane and Sound Response

What structure within the cochlea is shown unrolling and vibrating in response to sound?

• Auditory nerve

• Ossicles

• Basilar membrane

• Semicircular canals

How does the basilar membrane respond when a single, individual tone is played?

• It vibrates uniformly along its entire length.

• It vibrates at a specific, localized point.

• It remains completely still.

• It vibrates randomly without a clear pattern.

When a complex sound, such as a chord or music, is played, how does the basilar membrane respond?

• It vibrates at a single, intense point.

• It vibrates in a simple, repetitive pattern.

• It vibrates at multiple, distinct locations simultaneously.

• It only vibrates if the sound is very loud.

The process by which the ear breaks down complex sound waves into their individual frequency components is analogous to what mathematical analysis?

• Regression analysis

• Spectral analysis

• Factorial analysis

• Cluster analysis
