Factors Effecting Loudness of Sound:

 

Loudness depends on following factors:

– Area of Vibration of Body: Greater will be the surface area more will be the loudness.

– Amplitude of Motion of Vibrating Object: Greater will be the amplitude, more will be the loudness.

– Density of Medium: Loudness is directly proportional to the density of medium.

– Motion and Direction: If source of sound is moving towards the listener loudness will be greater or if wind supports the velocity of sound the loudness will be greater.
