Sound needs a material medium to propagate through, since sound does not pass through a vacuum. Therefore sound waves do not have a polarization property. Sound waves in solids are mainly compressional, but may have a small transverse component. Because liquid and solids have high coefficients of compressibility b sound travels much faster in these media than it does through a gas like air. A temperature increase or increased humidity will raise the speed slightly.
Audiology is the study of the perception of sound.
