introduction. Sound is a longitudinal, mechanical wave. Sound can travel through any medium, but it cannot travel through a vacuum. There is no sound in outer space. Sound is a variation in pressure. A region of increased pressure on a sound wave is called a compression (or condensation). A region of decreased pressure on a sound wave is called ...

Sound is produced by small and rapid pressure changes. Vibrating objects produce periodic sound waves. Sources include human vocal cords, musical instruments (strings, brass, reeds, drums, bells), speakers, buzzers, motors, etc. Implosive or explosive pressure changes produces sound pulses.
10 gru 2015 · ‘The nature of sound’ considers the physical aspects of sound, which are far better understood than the emotional ones. It discusses pressure waves; how sound is carried; the velocity, refraction, frequency, and diffraction of sound; the power of sound, including loudness and the decibel measurement system; standing waves and resonances ...
17 paź 2024 · Sound, a mechanical disturbance from a state of equilibrium that propagates through an elastic material medium. A purely subjective, but unduly restrictive, definition of sound is also possible, as that which is perceived by the ear.
In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. [1]
What's the science of sound? Understanding sound waves, sonic booms, and the speed of sound are key to understanding how X-59 will quiet the boom. The Physics of Waves. Waves are created when energy is transferred through a medium like water or air.
