Question

state three factors a on which loudness of sound heard by a listener​

Answer 1

Explanation:

the loudness of sound heard depends on: loudness is proportional to the square of the amplitude. loudness is inversely proportional to the square of the distance. loudness depends upon the surface area of vibrating body.

Answer 2

Answer:

Loudness of sound is a measure of response of sound to our ear. Loudness of sound is not simply the energy reaching the human ear, but it also tells about the sensitivity of human ear detecting this energy. Loudness of sound is measured in decibel (dB). As energy reaching the ear depends on square of amplitude, loudness of sound depends on various factors namely,

(i) Amplitude of sound waves

(ii) Sensitivity of ear

(iii) Distance from the source of the sound and the listener.
