3 11mbre is the distinguishing quality of a sound. It is the dimension of auditory experience reÂ­. lated to the complexity of the sound wave-to the. relative breadth of the range of frequencies that. make up the wave. A pure tone consists of only one. frequency, but in nature, pure tones are extremely. rare.
14.2. Sound Propagation and Absorption. As all waves, sound waves are characterised by speed, frequency and amplitude. Sound speed gives the magnitude of the sound velocity vector; it is expressed in units of m/s and symbolised by the symbol u (or sometimes by Ï or c). Sound frequency is the reciprocal of the period of the sound wave.
