To understand what causes an echo, you have to know something about sound. Sound travels at a speed of about 1,100 feet per second in the open air. It travels in waves, much like ripples made by a pebble thrown into the water. And sound waves go out in all directioas from the source, like the light from an electric bulb. Now, when a sound wave meets an obstacle, it may bounce back, or be reflected, just as light is reflected, When a sound wave is reflected in this way, it is heard as an echo. So an echo is sound repeated by reflection. Not all obstacles can cause echoes, however. Some objects absorb the sound instead of reflecting it This means the sound doesn't bounce back. There is no echo. But usually, smooth, regular surfaces, such as a wall, a cliff, a side of a house, or a vaulted roof, will produce an echo. If a sound is reflected by some obstacle, only one echo is heard. This is called a simple echo. If the sound is reflected by two or more obstacles, the echo may be repeated many times. When repeated more than once, it is known as a compound echo, or reverberation. The echo, however, becomes fainter each time until it dies away altogether. An echo cannot be heard as a separate sound unless the sound is made some distance away from the reflecting surface. This allows enough time between sound and echo. At a dUtanro n( 550 feet from a wall, for example, the echo returns in just one second. Answer to yesterday's Puzzle Box: When you put them "all together" — there is only one haystack!
