Century Dictionary and Cyclopedia
- n. A sound repeated by reflection or reverberation from some obstructing surface; sound heard again at its source; repercussion of sound: as, an echo from a distant hill. Sound being produced by waves or pulses of the air, when such waves meet an opposing surface, as a wall, they are reflected like light-waves (see
reflection); the sound so heard, as if originating behind the reflecting surface, is an echo. The echo of a sound returns to the point whence the sound originated if the reflecting surface is at right angles to a line drawn to it from that point. An oblique surface reflects the sound in another direction, so that it may be heard elsewhere, though not at the point where the sound originated. If the direct and reflected sounds succeed one another with great rapidity, which happens when the reflecting surface is near, the echo only clouds the original sound, but is not heard distinctly; and it is such indistinct echoes that interfere with the hearing in churches and other large buildings. An interval of about one ninth of a second is necessary to discriminate two successive sounds; and as sound passes through the atmosphere at the rate of about 1,125 feet in a second, of 1,125, or about 62 feet, will be the least distance at which an echo can be heard; and this will be distinct only in the case of a sharp, sudden sound. The walls of a house or the ramparts of a city, the surface of a cloud, a wood, rocks, mountains, and valleys produce echoes. Some echoes are remarkable for their frequency of repetition, and are called multipleor tautological echoes.

A single stop so used or placed is called an echo-stop.
