How is sound frequency measured?

Sound frequency is measured in cycles per second, which is known as Hertz (Hz). This unit quantifies how many complete waves (cycles) pass a given point in one second. For instance, if a sound wave completes 440 cycles in one second, it has a frequency of 440 Hz, which corresponds to the musical note A above middle C.

Understanding sound frequency is crucial in various applications, including acoustics and audio engineering. Higher frequency sounds are perceived as higher pitches, while lower frequencies correspond to lower pitches. While decibels measure the intensity or loudness of the sound, making it another important aspect of sound, it does not directly measure frequency. Similarly, volts and amps relate to electrical measurements and are not applicable to the measurement of sound frequency.
