Question

Name the characteristics of a vibrating body which determines the loudness and pitch of the sound produced by it

Answer 1

Hey dear,

● Answer -
(a) Amplitude => Loudness
(b) Frequency => Pitch

● Explaination -
# Loudness -
- Loudness refers to how loud or soft a sound seems to a listener.
- Loudness increases with increase in amplitude of sound waves.

# Pitch -
- Pitch is the degree of highness or lowness of a tone of sound.
- Pitch increases as frequency goes higher.

Hope this helps you.

Answer 2

Answer:

The intensity or loudness of a sound depends upon the extent to which the sounding body vibrates, i.e., the amplitude of vibration. A sound is louder as the amplitude of vibration is greater, and the intensity decreases as the distance from the source increases. Loudness is measured in units called decibels. 

Loudness is proportional to the square of the amplitude.
