Robins PART 1 ACOUSTICS and PROPERTIES OF SOUND Sound is Produced by Vibration With a Guitar, for example: THE VIBRATING STRING(vibrates) THE AIR(vibrates)THE EARDRUM the vibration of the eardrum produces the sensation of sound Noise is the result of irregular vibration patterns Tones are the result of regular vibrations Tones have 4 basic characteristics Pitch: high or low Duration: length of the sound Intensity: volume or loudness Timbre: "color" of the sound Let's examine further the action of a plucked string (the principle is, of course, the same for a vibrating column of air, or a vibrating membrane, etc.): When you pluck the string from it's resting point (a) it goes up to (b), back past (a) to (c), and then back to (a), it has completed one cycle.
