How is sound measured?
Sound waves are usually described with two measurements: frequency and amplitudeThe maximum displacement (difference between an original position and a later position) of the material that is vibrating. Amplitude can be thought of visually as the highest and lowest point of a wave.. Frequency means the number of waves passing a given point in a given period of time. This is usually measured in hertzThe unit of measurement of frequency; a measure of the number of waves that pass a given point per second of time., abbreviated Hz. One hertz equals 1 cycle per second. Humans can usually hear sounds with frequencies from 20 Hz to 20,000 Hz. The
faster a wave vibrates, the higher its frequency and the higher a...
