Question

Explain:

1)pitch

2)loudness

3)quality of sound

Answer 1

(i) Pitch: It is that characteristic of sound which helps to distinguish between a shrill and a hoarse sound. Pitch of a sound is the sensation which depends upon frequency.

(ii) Loudness : It is the characteristic of sound which helps to distinguish between a loud sound and a faint sound. A loud sound has a large energy associated with it.
sound loudness is a subjective term describing the strength of the ear's perception of a sound. It is intimately related to sound intensity but can by no means be considered identical to intensity.

(iii) Quality or Timbre : It is the characteristic of a sound which helps us to trace source i.e., whether it is from Tabla or Guitar. It is this characteristic of sound by which we can recognise a friend only from his voice.
