Detailed explanation-1: -Frequency in a sound wave refers to the rate of the vibration of the sound travelling through the air. This parameter decides whether a sound is perceived as high pitched or low pitched. In sound, the frequency is also known as Pitch. The frequency of the vibrating source of sound is calculated in cycles per second.
Detailed explanation-2: -Frequency refers to the number of cycles per second of the sound wave. Frequency is measured in Hertz (Hz), 1 Hz equals one cycle per second. Human hearing is approximately within the range of 20Hz-20, 000Hz.
Detailed explanation-3: -The lower the frequency, the fewer the oscillations. High frequencies produce more oscillations. The units of frequency are called hertz (Hz). Humans with normal hearing can hear sounds between 20 Hz and 20, 000 Hz.
Detailed explanation-4: -pitch, in music, position of a single sound in the complete range of sound. Sounds are higher or lower in pitch according to the frequency of vibration of the sound waves producing them.
