METHOD FOR WEAKENING INTENSITY OF ACOUSTIC WAVES

摘要

A method for weakening intensity of acoustic waves is in weakening intensity at propagation of those through multi-layer solid barrier. Longitudinal air acoustic wave is transformed to nonpolarized transverse wave by passing through first layer of solid material that is characterized with arbitrary direction of fiber, after that it is polarized by passing through second layer of solid material – polarizer that is characterized with given direction of fiber, after that it is repetitively polarized by passing through third layer of solid material – analyzer that is characterized with normal direction of fiber with respect to previous layer.
