The sound waves of irregular vibration in matter is called noise.
Different is the speed of propagation. Scroll down to related links and look at "Acoustic or sound waves in air - Radio and light waves in a vacuum".
there is no air in a vaccum. and sound needs air for the sound waves to travel through.
Sound waves travel through a material via VIBRATION. When sound waves hit an object at one end, the object's molecules at that end starts vibrating and during this vibratory motion they transfer their energy to neighboring atoms, hence cause a chain vibration and ultimately the waves reach at the other end.
sound is produced by vibration, i.e. when any thing start vibration then it produces sound. for example when a tunnig fork is hit on rubber pad its prongs starts vibration with difinit frequency ad hence produce sound. similarly when the strings of a gittar is dirturbed its starts vibration and hence produces sound. sound required a material medium for their journey, sound can not pass through vaccume because sound waves are mechanical waves.
Sound is, at its basic level, the motion of moving particles. In the quantum mechanical picture, energy of vibration of atoms or molecules is described as phonons. Phonons are a quanta (packet) of energy that can be treated as a particle (matter). At the full level, it is mechanical or material waves that is an oscillation of pressure. In others words, yes and no.
Sound moves by vibration. It is conducted by the vibration of matter. That vibration oscillates up and down in crests and troughs (hi's and low's). The distance or "wave length" between one crest and the next is a sound wave.
Sound waves are produced due to the vibrations of an object .Sound waves are produced by vibration. Everything on this earth causes some sort of vibration. When something vibrates it produces a sound.
The reflection is vibration because sound is equal to vibration
Sound energy is produced when matter vibrates. This vibration creates waves that travel through a medium, such as air or water, and are interpreted by our ears as sound.
Mechanical waves require matter to transfer energy. Examples include sound waves in air, water waves in the ocean, and seismic waves in the Earth's crust. These waves are caused by the vibration of particles in the medium through which they travel.

Vibration from sound waves
All types of waves vibrate as they transport energy without transporting matter. Examples include light waves, sound waves, and water waves. The vibration of the waves determines their frequency and wavelength.
A wave is a vibration that passes through a substance without permanently changing the substance. Waves transfer energy without displacing matter permanently. Examples include sound waves and light waves.
The transfer of energy from a vibrating object in waves that travel through matter is known as sound. Sound waves are produced by the vibration of particles in a medium (such as air, water, or solids) and are characterized by properties such as frequency, amplitude, and wavelength.
the sound waves are the matter wave, which always require a medium to travel. Because matter waves travel due to vibration in matter or energy transformation via consecutive particles from the source to the destination. Since in vacuum there is no medium via waves as energy can transfer ,so sound can not travel in vacuum.
The vibrations caused by sound waves onto your eardrums are pressure compressions and rarefactions.
