Can sound waves be polarized just as light waves?
Can these methods be used in everyday scenarios or are they only used in specialized applications?
While some of these methods are still experimental or only used in specialized applications, others have practical applications in everyday scenarios. For example, acoustic lenses are used in cellphone speakers and some hearing aids, while metamaterials are being developed for use in noise-cancelling technology and building materials that absorb sound.
