CCCH9008 Noise Pollution and Control in HK Two important characteristics of sound or noise Frequency of Sound Sound is the quickly varying pressure wave travelling through a medium. When sound travels through air‚ the atmospheric pressure varies periodically. The number of pressure variations per second is called the frequency of sound‚ and is measured in Hertz (Hz) - cycles per second. Loudness A loud noise usually has a larger pressure variation and a weak one has smaller pressure variation
