Question

NCERT VIII - Sciences

Fill in the blanks:

(b) Loudness is determined by the________ of vibration.

Answer 1

BY THE AMPLITUDE OF VIBRATION

Answer 2

Loudness is determined by the frequency of vibration and the loudness of vibration is determined by its size, which is expressed by the scale of amplitude.

With sound waves, it is the degree to which air atoms are displaced, and this amplitude of sound or sound amplitude is felt as the loudness of sound.

We mostly decipher amplitudes in a specific logarithmic unit, it is named decibels.
