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.
Sound above the hearing range is known as ultrasound, and that below the hearing range as infrasound. The amplitude of a sound wave is specified in terms of its pressure. The human ear can detect sounds with a very wide range of amplitudes and so a logarithmic decibel amplitude scale is used.
