WHEN a gong is struck, it is thrown into a series of vibrations, and, as a result, the surrounding ocean of air is set a-trembling. Each particle taps the one next to it, and thus the commotion, or wave, advances, much in the same way as it may do along a row of billiard balls, placed at short intervals, when the end ball is struck. This transference of vibration through the atmosphere is termed a sound-wave, which is thus purely physical in its nature. Let us now suppose the wave to strike upon the ear; an impression is flashed along the nerves of hearing to the brain, and a sound is heard. There are thus two kinds of sound, and it is very important to distinguish clearly between them-the sound of the natural philosopher, which is a purely physical phenomenon, and the sound of the mental philosopher, which is a purely psychical phenomenon. We may conveniently term the one "physical sound," and the other "psychical sound." |
