The form of energy called sound is produced when matter moves or vibrates. The vibrations are transferred to another medium, usually the air, and travel through it as sound waves. You hear a sound when its vibrations reach your eardrum, causing it to vibrate. The pitch of a sound is dire...
In subject area: Physics and Astronomy Noise (Sound) refers to a type of sound that contains all frequencies equally, perceived as 'hissy' due to high-frequency energy predominating over low-frequency energy. It can be modified in various ways such as low-passed filtered noise, pink or red...
Power is the rate at which energy is transferred by the wave. In equation form, intensity I is I=PAI=PA, where P is the power through an area A. The SI unit for I is W/m2. The intensity of a sound wave is related to its amplitude squared by the following relationship: I=(Δp...

The Physics of Sound Assume the simple motion of a moving string. The instrument can be a violin, a guitar string, piano, sitar, or banjo string, which excites movement by plucking, striking/bowing it. As a matter of fact, it makes no difference because the acoustic laws are the same ...

Sound generation is an energy conversion process: energy is transferred from the source of excitation into the wave field, manifesting itself as pressure fluctuations. The more effective the process of sound generation, the greater power transmitted by the wave, and the larger the amplitude of ...
