Question

loudness of a sound decreases with------------in its amplitude​

Answer 1

Answer:

The loudness of sound depends on the amplitude of wave. On decreasing the amplitude of the sound wave, its loudness gets decreased. We know that the intensity of a wave is directly proportional to the square of its amplitude. As a result, on decreasing the amplitude of a wave, its intensity gets decreased

Answer 2

Explanation:

loudness of a sound decreases with decrease in its amplitude .
