Because it is pressure that actually propagates through the medium. When air is the medium, air molecules are displaced outward and then back, in unison with the sound generating object. This 'wave' of pressure, much like a ripple on water, moves through the air outward from the source.

∙ 8y agoAll "waves" are energy. In this case, music is a tremendously complex series of waves caused by air compression of differing frequencies, phase, and amplitude. But they are still waves, caused by movement of the air - basic physics tells you that moving air has force (however small) and therefore energy.

∙ 11y agoWe have the static atmospheric pressure of about 101,325 pascals. A sound wave traveling through air will cause a pressure variation in the air. The air motion which accompanies the passage of the sound wave will be back and forth in the direction of the propagation of the sound, a characteristic of longitudinal waves. Sound pressure or acoustic pressure is the local pressure deviation from the ambient atmospheric pressure caused by a sound wave. Sound pressure in air can be measured using a microphone. The SI unit for sound pressure p is the pascal with the symbol Pa = N/m².

Why can't you hear clearly underwater?
Sound waves accessible by humans are attenuated in water.
Why is the vibration of an object necessary for a sound wave to form?
"Sound waves" are basically pressure waves - areas of higher and lower pressure, that propagate as a wave. You must have SOME means to create those pressure changes, and to do so quickly.
What slows down sound waves?
according to the equation v=1/2{gamma *pressure /density} sound waves are slowed down by=decreasing pressure and increasing volume,temparature,density of the medium
The process of sound waves travelling to the brain is known as what conduction?
The process of sound waves travelling to the brain is known as sensorineural conduction. Hearing loss may be sensorineural, conductive or a mixture of both.
Do sound waves always travel in straight lines explain?
No, Sound is a pressure wave not a linear wave, the waves radiate spherically from their point of origin. Also as a pressure wave, it travels in a medium and if that medium is moving the sound wave propagation can be modified by that movement (bent). They also behave like sea waves impinging on a headland and can be bent round objects in their path in complex ways.
Why are sound waves are described as pressure waves?
Sound waves are described as pressure waves because waves produces pressure by which sound is produces
Sound waves are what waves?
Sound waves are longitudinal waves, which transfer energy by compressing particles, which then apply pressure on the particles infront of them. The point at which the particles are compressed is known as the compression, whereas the point at which the particles are most spaced out is known as the rarefaction
What type of sound wave are they that they allow sound to travel?
Sound waves are pressure waves.
What waves reach our ears?
Sound (pressure) waves.
What are sound waves made up?
pressure waves
Waves that disturb matter?
Sound waves, pressure waves, longitudinal waves.
What are a sound wave?
Yes, sound waves are pressure waves that travel through matter.
What are some examples of longitude waves?
sound waves aka pressure waves
What waves reach our ears on playing guitar?
Sound waves (which are pressure waves).
What does amplitude of a sound wave determine?
Amplitude is the volume of the sound in sound waves. The higher the Amplitude, the louder is the sound. Sound waves are pressure or compression waves in the material through which the sound is traveling. The pressure or compression waves also result in small longitudinal displacements of the atoms or molecules. The amplitude of the sound wave determines the range of variation of pressure, compression, or displacement.
Sound waves are what kind of waves where atoms are squeezed together?
Sound waves are known as longitudinal waves.
Sound can best be thought of as?
Pressure waves.
