Question

list out the four difference between loudness and pitch of the sound.​

Answer 1

Answer:

Loudness of sound:-

•    This phenomenon of a sound depending on the amplitude of the sound wave. If the amplitude of the sound wave is large, then the sound is said to be loud.

•    It is directly proportional to the square of the amplitude of vibration. If the amplitude of the sound wave becomes double, then the loudness of the sound will be quadrupled.

•    It is expressed in decibel (dB).

•    Sounds above 80 dB becomes noise to human ears.

•    The table given below gives us data for various sources of sound.

                  Pitch of sound:-

•   This depends on the frequency of vibration of the waves.

•    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.

•    A bird produces high-pitched sound whereas roaring of a lion is a low-pitched sound.

•    The Voice of a woman has a high pitch than that of a man

Difference between sound and pitch

• These two phenomena seem to be the same sometimes, but they are not exactly the same. They differ on the basis of their tone quality. The pitch of a sound is our ear’s response to the frequency of sound. Whereas loudness depends on the energy of the wave. In general, the pitch is the reason behind the difference in voice quality of different individuals.
