Facts About Sound Sound is actually an energy wave of molecules that create a vibration. Sound can travel through and bend around many objects, including water. Check out how sound works: 1  When an object moves it creates a vibration. 2  Vibrations move air particles around. 3  These moving particles are constantly bumping into each other. 4  Our ears can pick up these particle-vibrations as sound. 5  Fast moving particles create a high sound, while slow ones are low-sounding.

sound The definition of sound is someone or something that is in good condition. An example of sound is a well made chair. Sound is vibration in air and water that stimulate the nerves inside the ears to create the sensation of hearing. An example of sound is music. An example of sound is voices. The definition of a sound is a wide channel or strait linking two large bodies of water.

Sound In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a transmission medium such as air or water. In physiology and psychology, sound is the reception of such waves and their perception by the brain.

What Is Sound? Musical sounds typically have a regular frequency, which the human ear hears as the sound’s pitch. Pitch is expressed using musical notes, such as C, E flat, and F sharp. The pitch is usually only the lowest, strongest part of the sound wave, called the fundamental frequency.

Sound and wind Sound is a rapid small variation of the air pressure. The pressure variation is usually between +100 Pa and ‑100 Pa, and is then at least 1000 times smaller than the mean air pressure (Pa is the symbol for pascal, a unit of pressure).

Mimicry In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a transmission medium such as air or water. In physiology and psychology, sound is the reception of such waves and their perception by the brain. Humans can hear sound waves with frequencies between about 20 Hz and 20 kHz. Sound above 20 kHz is ultrasound and below 20 Hz is infrasound.

- Sounds may be generally characterized by pitch, loudness, and quality. Sound quality or timbre describes those characteristics of sound which allow the ear to distinguish sounds which have the same pitch and loudness. Timbre is then a general term for the distinguishable characteristics of a tone.

What is a sound wave? Originally Answered: What is a sound wave? Sound is a form of energy and it travel in to and fro curved pattern is called wave. sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (solid ,liquid and gas) as it propagates away from the source of the sound.

sound (sound) 1. a pressure wave propagating through an elastic medium; waves with a frequency of 20–20,000 Hz cause the sensation of hearing. 2. the effect produced on the organ of hearing by vibrations of the air or other medium. 3. a noise, normal or abnormal, heard within the body.

- The definition of sound says that it is a disturbance of energy that comes through matter as a wave, and that humans perceive sound by the sense of hearing. Sound pressure is the effect and sound power (energy) is the cause.But our eardrums are only sensitive to the sound pressure, and so are microphone diaphragms.he energy in a sound wave is both kinetic and potential. Just as in a vibrating spring, the medium has mass a … nd moves and so moving mass is kinetic energy. Just as in the spring there is compression and rarefaction, so there is elastic potential energy.

Sound Noise is a term often used to refer to an unwanted sound. In science and engineering, noise is an undesirable component that obscures a wanted signal. However, in sound perception it can often be used to identify the source of a sound and is an important component of timbre perception (see above).

What Is Sound? All sounds are vibrations traveling through the air as sound waves. Sound waves are caused by the vibrations of objects and radiate outward from their source in all directions.mplitude (or intensity) refers to the strength of a sound wave, which the human ear interprets as volume or loudness. People can detect a very wide range of volumes, from the sound of a pin dropping in a quiet room to a loud rock concert.
