Professor Bain distinguishes sounds considered as sensations into three classes: The first comprises the general effects of sound as determined by quality, in�tensity, and volume or quantity, to which all ears are sensitive. The second includes musical sounds, for which a susceptibility to pitch is requisite. Lastly, there is the sensibility to the articulateness, distance, and direction of sounds, which are the more intellectual properties. The first and principal difference between
sounds experienced by the ear is that between noises and musical tones, every variety of which depends on the rapidity, form, size, and order of succession of the vibrations. In musical tones, the vibrations are periodic, or succeed each other at regular intervals; in noises, they follow each other irregularly. Musical tones be�gin to be perceived at about thirty vibrations in a second, but a determinate musical pitch is not per�ceptible till about forty vibrations have been reached.
