<P> Sound is a traveling longitudinal wave which is an oscillation of pressure . Humans perceive frequency of sound waves as pitch . Each musical note corresponds to a particular frequency which can be measured in hertz . An infant 's ear is able to perceive frequencies ranging from 20 Hz to 20,000 Hz ; the average adult human can hear sounds between 20 Hz and 16,000 Hz . The range of ultrasound , infrasound and other physical vibrations such as molecular and atomic vibrations extends from a few femtohertz into the terahertz range and beyond . </P>
