pitch
Quick Summary
Pitch refers to the perceived highness or lowness of a sound, determined by the frequency of sound waves. The human ear can distinguish pitch by analyzing these frequencies, typically measured in hertz (Hz). A higher frequency corresponds to a higher pitch, while a lower frequency results in a lower pitch. In music, pitch is a fundamental element used to create melodies and harmonies, with standardized pitches like A=440 Hz used for tuning. The range of human hearing for pitch extends from approximately 20 to 20,000 Hz.1234

sound receptionAuditory sensitivity of fishes…distinguish between tones of different frequencies is of special interest. Two studies dealing with this problem have shown that the frequency change just detectable is about four cycles for a tone of 50 hertz and increases regularly, slowly at first, then more rapidly as the frequency is raised.
