What determines "loudness"?
A) the wave frequency or number of vibrations per second
B) As the fluid in the cochlea vibrates with more force, the basilar membrane moves with greater force.
C) the number of hair cells that are stimulated
D) As the noise gets louder, the auditory tube expands.
E) The auditory cortex assigns greater volume to sounds coming from sources that are visually recognized as being louder.
Basilar Membrane
A structure in the cochlea of the ear that vibrates in response to sound and aids in the process of hearing.
Wave Frequency
The number of waves that pass a fixed point in unit time, typically measured in hertz (Hz).
Auditory Tube
Also called the eustachian tube; connects the middle ear to the nasopharynx for the equalization of pressure.

Final Answer :
B
Explanation :
Loudness is determined by the amplitude or intensity of sound waves, which cause the fluid in the cochlea to vibrate with more force. This, in turn, causes the basilar membrane to move with greater force, stimulating more hair cells and signaling to the brain that the sound is louder.
