Answer 2

Characteristics of Sound :-

• The factors which makes sounds different from each other are called Characteristics of Sound .
• These factors are loudness , pitch and quality .

Loudness :-

• Loudness of the sound produced by a vibrating object depends on the amplitude of vibration.
• The amplitude is doubled , the loudness increases four times.

Pitch :-

• Pitch is a measure of how high or low a sound is .
• The higher the frequency , the more high-pitched sound .

Quality :-

• The quality of a sound is determined by the frequencies present in it and thier relative loudness .
