That sounds very much like the definition of sound waves - or more precisely pressure waves, which is what sound waves are.
The waves in a sound wave are a series of compressions and rarefactions of some medium, which is normally thought of as air, but can be in water, and other liquids, and solids. In a vacuum there is nothing to compress.
Rarefactions decompressions travel in the same direction, because sound are longitudinal waves.
Sound travels from one place to another as a result of vibrations. When an object or a source of sound such as a speaker vibrates, it creates compressions and rarefactions in the surrounding medium, usually air. These compressions and rarefactions are propagated as waves, which travel through the air and reach our ears, allowing us to perceive the sound.
Sound waves are LONGITUDINAL. This means the direction of the particles is the same as the direction of the wave. Sound waves are a series of compressions (areas of high density) and rarefactions (areas of low pressure). All sound waves are caused by vibrations. They only travel if there is a medium for them to travel along, therefore there is no sound in space, or in a vacuum as it cannot travel.
Longitudinal waves travel in a medium due to alternate compression & rarefactions ie. they travel due to variation in pressure.

With the help of compressions and rarefactions longitudinal waves get propagated.

sound is a lonitudnal wave nd travels in the form of compressions and rarefactions..

Sound is a mechanical wave. It needs material medium to travel. The sound from the airplane reaches your ear through air in the form of alternate compressions and rarefactions.
Sound (and vibration) are a wave system of sequential compressions and rarefactions of a material. These waves are mechanical and do need a substance through which to travel. They cannot travel through a vacuum.
Sound waves traveling through air are indeed longitudinal waves with compressions and rarefactions. As sound passes through air (or any fluid medium), the particles of air donot vibrate in a transverse manner.Soundis produced when something vibrates. The vibrating body causes the medium (water, air, etc.) around it to vibrate. Vibrations in air are called traveling longitudinal waves, which we can hear. Sound waves consist of areas of high and low pressure called compressions and rarefactions, respectively.
