Every kind of sound is produced by vibration. The sound source may be a click of a button, an automobile horn, or a hounding wolf. These waves travel out in all directions, expanding in balloon like fashion from the source of the sound. The vibrations from the source disturb the air in such a way that sound waves are produced. Vibrations that are perceived as sound, if the waves happen to reach someone’s ear, they set up. Sound, depends on three things. There must be a vibrating source to set up sound waves, a receiver to detect them, a medium to carry the waves, and. Sound waves cannot travel through a vacuum. There is an age-old question concerning the definition of sound. If a lamppost falls in a road far from any sound detector (such as a human ear or a microphone), does the lamppost’s crash make any noise? The answer, obviously, depends on how sound is perceived. If it is thought of as the waves that are carried by the air, the answer is yes—wherever there are sound waves there is sound. Whatever it is, some part of it is vibrating while it is producing sound
