question 9 of 10
if you are seated in the back of a large auditorium and you cannot hear the speaker in the front, what aspect of sound needs to be altered to remedy the situation?

a. amplitude of sound.
b. velocity of sound
c. spectrum of sound
d. frequency of sound

Explanation:

The amplitude of a sound wave is related to its loudness. Increasing the amplitude makes the sound louder, which is what is needed when one can't hear in the back of an auditorium. Velocity of sound is mainly determined by the medium and not a factor for making the sound more audible in this context. The spectrum of sound refers to the range of frequencies present and frequency is related to pitch, not loud - ness.

Answer:

A. amplitude of sound
