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.
Amplitude, or the dimension of a wave from peak to trough, in sound is heard as volume and is illustrated in Figure 17.12. The sound waves of louder sounds have greater amplitude than those of softer sounds. For sound, volume is measured in decibels (dB). The softest sound that a human can hear is the zero point.
