The oscillating variations in sound pressure (called the WAVEFORM of the sound) PROPAGATE in the form of a SOUND WAVE. See: ACOUSTIC IMPEDANCE, COMPRESSION, LAW OF SUPERPOSITION, PARTICLE VELOCITY, ...

Sound waves can reflect off surfaces ... runs from the middle ear to the back of the nose and makes sure that the pressure is the same on both sides of the eardrum. When your ears pop the eardrum ...

Compared to the much stronger airflow from the box fan that was also used in one attempt, the difference with the sound waves is that they oscillate, constantly fluctuating the air pressure.

And when that shock wave, traveling at the speed of sound, sweeps past you on the surface, you hear and feel the release of the pressure that the shock wave has built up as a great BOOM-BOOM.

NASA has turned pressure waves emanating from a black hole at the centre of the Perseus galaxy cluster into notes audible to humans. The sound waves were extracted along the radius of the galaxy ...

"Surprisingly, sound waves and ocean waves have a lot in common ... Wave breaking results in high energy or pressure densities. There is a hypothesis that turbulence is caused by such collapses ...

Pressure changes can be plotted on a waveform, which highlights the air particles being compressed and rarefied, creating sound waves that spread outwards. A tuning fork being struck can provide an ...
