The pitch of the sound depends on frequency. Pitch refers to the specific quality of the sound that makes it sound “higher” and “lower” in the sense associated with musical melodies. The higher or lower pitch of the sound is based on the frequency of vibration of the sound waves producing them. The response of the human ear to the frequency of sound is the pitch of the sound.

Factors Depending on the Pitch of Sound

Sound refers to the waves that are produced when particles of the medium vibrate in the direction in which they move. When these particles get in contact with each other, what we hear is called a sound. The Pitch of a Sound is the response of our ears in response to the sound. On the other hand, the loudness of a particular sound depends on the sound waves.

Pitch depends on a factor known as frequency. A high-frequency sound wave results in a high pitch sound whereas a low-frequency sound wave results in a low-pitch sound.

  • The normal frequency range of human beings to hear sounds is between 20 Hz and 20,000 Hz.
  • All the sounds that have a frequency above 20,000 Hz are known as ultrasound.
  • Frequency is always measured in Hertz (Hz).


On What Factor does the Pitch of a Sound Depend?

The factor on which the pitch of the sound depends is the frequency. Pitch defines the quality of a sound by determining its frequency scale, which is measured in the unit called Herts (Hz). The relationship between pitch and frequency is proportional. The higher the frequency the higher the pitch and vice-versa.
