Question

Sound is a mechanical wave which travels through a medium from one location to another. As a sound wave reaches the end of its medium, it undergoes certain characteristic behaviours. Whether the end of the medium is marked by a wall, a canyon cliff, or the interface with water, there is likely to be some transmission/refraction or reflection occurring. Reflection of sound waves from barriers result in some observable behaviours which you have likely experienced.If you have ever been inside of a large canyon, you have likely observed an echo resulting from the reflection of sound waves off the canyon walls. Suppose you are in a canyon and you give a holler. Shortly after the holler, you would hear the echo of the holler - a faint sound resembling the original sound. This echo results from the reflection of sound off the distant canyon walls and its ultimate return to your ear. A reverberation is perceived when the reflected sound wave reaches your ear in less than 0.1 second after the original sound wave. Since the original sound wave is still held in memory, there is no time delay between the perception of the reflected sound wave and the original sound wave. The two sound waves tend to combine as one very prolonged sound wave. If you have ever sung in the shower, then you have probably experienced a reverberation. 1.
