Question

What is loudness of sound ?What factors dors it depend on ?​

Answer 1

Answer:

The loudness of a sound is a perceptual measure of the effect of the energy content of sound on the ear. It is related to the decibel (dB) which is an logarithmic scale used to quantify the power of a sound.

Loudness and softness of sound depends on the amplitude of the wave. More the amplitude, more is the loudness.

Answer 2

Answer:

The loudness of sound is a phenomenon of a sound depending on the amplitude of the sound wave. If the amplitude of the sound wave is large, then the sound is said to be loud. The loudness of sound is directly proportional to the square of the amplitude of vibration and it is expressed in decibel (dB).
