Question

What are the factors in which the loudness depends

Answer 1

Definition :

Loudness is the characteristic property by which can distinguish two sounds of the same frequency and pitch.

We can distinguish between a faint sound from a loud sound using the property .

Factors affecting loudness

• Loudness is directly proportional to the square of amplitude .

• Loudness is inversely proportional to the square of distances.

• Loudness is directly proportional to the surface of a vibrating body.

• Loudness is directly proportional to the density of the medium.

Loudness is measured in decibels.

A sound having more than 120 dB is considered to be a noise pollutant .

Answer 2

Answer:

LOUDNESS:-)

loudness is the amount of energy crossing unit area around a point in one second.

Main factors on which loudness depends :-)

1》 lntensity which depends on amplitude and is proportional to the square of the amplitude.

2》 The surface area of the sounding body.

3》Density of the medium.

4》The distance of the source from the listener.

5》 The presence of other resonant object around the surrounding body.

6》 The motion of the air.
