Question

Loudness is a sensation depending upon . a)time period b) phase c) velocity d) wavelength​

Answer 1

Answer:

The intensity or loudness of a sound depends upon the extent to which the sounding body vibrates, i.e., the amplitude of vibration. A sound is louder as the amplitude of vibration is greater, and the intensity decreases as the distance from the source increases. Loudness is measured in units called decibels.

Loudness is proportional to the square of the amplitude

Answer 2

Answer:

Loudness relies upon intensity of sound and intensity of sound is the amplitude of sound waves.
