What is the unit of measurement designated for frequency?

The correct unit of measurement designated for frequency is hertz (Hz). This unit quantifies the number of cycles or occurrences of a periodic event per second. In the context of sound, it measures how many sound waves are produced in one second, which directly affects the pitch of the sound heard by an individual. For example, a sound frequency of 440 Hz indicates that 440 cycles of the sound wave occur in one second, which corresponds to the musical note A above middle C.

Other units mentioned, such as decibels (dB), are used to measure sound intensity or loudness, while watts (W) measure power, and ohms (Ω) measure electrical resistance. These units are important in their respective fields but do not pertain to frequency measurement. Hence, hertz is specifically the unit utilized within the realm of audio and sound science to describe frequency accurately.
