Frequencies are measured in which unit?

Explanation:
Frequency is how many times something repeats per second. For sound, it’s how many pressure oscillations occur each second. The standard unit for that rate is the hertz, defined as one cycle per second. Higher frequencies mean more cycles per second, like 440 Hz for the note A above middle C. Other units shown aren’t measuring how often a cycle occurs: pascals measure pressure, decibels measure sound level on a logarithmic scale, and meters per second measure velocity. So the unit for frequencies is hertz.
