Question

Differentiate between Loudness and pitch.

Answer 1

Loudness	Pitch
This phenomenon of sound depends on the amplitude of the sound wave. If the amplitude of the sound wave is large, then the sound is said to be loud.	If the frequency of vibration is higher, we say that the sound is shrill and has a high pitch. On the other hand, if the sound is said to have a lower pitch then it has a lower frequency of vibration.
Loudness is defined as the property of sound which is used for differentiating between the loud and faint sound.	Pitch is defined as the characteristic of sound which is used for differentiating between the shrill and flat sound.
Loudness is dependent on the energy received by the ear in unit time.	Pitch is independent of the energy received by the ear in unit time.
Loudness is independent of the change in frequency.	Pitch is dependent on the change in the frequency. As the frequency increases, the shrillness of the sound increases.
It is expressed in decibel (dB).	It is expressed in Hertz (Hz).
Ex : Sound of the footstep has very low amplitude while loudspeaker has high amplitude.	Ex : Bird produces high pitched sound whereas roaring of a lion is a low-pitched
