Question

What is loudness of sound? What factors does it depend on?

Explain in detail.

Answer 1

The  loudness of softness of a sound depends upon it's amplitude. The amplitude of the sound wave depends upon the force with which an object is prepared to vibrate.

Loud sound can travel a longer distance as it is associated with higher energy while soft sound can travel a shorter distance as it is associated with less energy. A sound wave spreads out after it leaves its source of production and as it moves away from the source its amplitude and its loudness decreases.

Loudness depends upon amplitude, intensity of sound and sensitivity of the ear.

Hope it helps :-)

Answer 2

loudness is the property by virtue of which allowed sound can be distinguished from a faint one both having the same pitch and quality.

loudness of a sound depends on amplitude of the wave. louder sound corresponds to a wave of larger amplitude.

==============================

the factors affecting the loudness of sound :-

1)loudness is proportional to the square of the amplitude .

2) loudness varies inversely as the square of the distance

3)loudness this depends on the surface area of the vibrating body .

4)loudness depends on the density of the medium more the density of the media more is the loudness .

5)loudness depends on the presence of resonant bodies . the presence of resident bodies near the vibrating body increases the loudness of sound
