What is noise frequency?

Noise frequency refers to the rate at which sound waves oscillate, measured in hertz (Hz). In the context of sound, it describes the pitch of the noise, with higher frequencies producing higher pitches and lower frequencies resulting in deeper sounds. Noise can encompass a wide range of frequencies, from low-frequency rumbling (like thunder) to high-frequency sounds (like a whistle). Understanding noise frequency is important in fields like acoustics, audio engineering, and environmental noise control.
