Frequency is measured in which unit?

Frequency is measured in Hertz (Hz), which is the unit defined as cycles per second. This means that if a sound wave oscillates or cycles once in one second, it has a frequency of 1 Hz. The concept of frequency is crucial in audiology because it relates directly to the pitch of a sound; higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches.

Other units mentioned, such as decibels (dB), measure sound intensity or loudness, not frequency. Watts (W) pertain to power and Newtons (N) measure force, which are both irrelevant in the context of measuring the frequency of sound waves. This makes Hertz the appropriate unit for frequency in the field of audiology and acoustics.
