Key Point Of Elastic Waves, Acoustics:
Acoustic waves travel with the characteristic acoustic velocity that totally depend on the medium they are passing through.
Acoustic waves are elastic waves that exhibit phenomena like diffraction, reflection and interference. Note that sound waves in air, however, don't have any polarization since they oscillate along the same direction as they move.
Acoustics is the branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics including vibration, sound ultrasound, and infrasound. An acoustician is a scientist who works in the field of acoustics while someone who works in the field of acoustics technology might be considered an acoustic engineer.
