Question

State three difference between loudness and pitch.

Answer 1

When the sound has larger amplitude, the sound is said to be loud. So, the loudness of the sound is dependent on the amplitude of sound.
When the sound has higher frequency, the pitch of sound is high. So, the pitch of the sound is dependent on the frequency of sound.

Complete step-by-step answer:
The vibration produced in the medium is known as the sound. The wave of sound has some characteristics. The characteristic of sound is as follows:

i. Amplitude: Amplitude of the sound wave is displacement of the sound from mean position.
ii. Frequency: The frequency of the sound is the number of waves passing in given time.
iii. Wavelength: The distance between two successive crest and trough is the wavelength.

The difference between the loudness and the pitch of the sound:

Loudness	Pitch
Loudness is the phenomenon of the wave of sound which is dependent on the amplitude of the wave.	Pitch of the sound is dependent on the frequency of the wave
Loudness is directly proportional to the square of the amplitude.	The pitch of the sound is directly proportional to the frequency of the sound.
The unit of loudness is decibel.	The unit of pitch is Hertz.

Note: Human ear can hear the sound having loudness below 80 dB. If loudness is higher than 80 dB, it is not audible for the human ear.
When the pitch of the sound is higher, the sound is shrill.
Example:
The pitch of the sound is higher for women as compared to men.
The pitch of the sound is higher for birds as compared to Lion.
