A) The response of the ear to sound of increasing intensity is approximately logarithmic.	B) The sensitivity of the human ear does not vary with the frequency of the sound.
C) When two or more waves traverse the same medium, the displacement of any element of the medium is the algebraic sum of the displacements due to each wave.	D) Longitudinal waves can travel in all media-solids, liquids and gases.

Answer & Explanation Answer: B) The sensitivity of the human ear does not vary with the frequency of the sound.

Explanation:

The human ear can respond to minute pressure variations inthe air if they are in the audible frequency range, roughly 20 Hz -20 kHz. In fact, tests conducted show an increased sensitivity in the 3000 Hz range which is the optimal amplification frequency in the human ear. So, the sensitivity of the human ear varies with the frequency of the sound.
