Abstract
A sound barrier (22) comprising a pair of spaced apart members (24,26), a medium (34) disposed between the members capable of propagating sound waves, and one or more acoustical resonators (30) coupled to the medium and tuned to one or more selected frequencies. The resonators may be disposed between the members or may be disposed around the outer periphery of the members to permit construction of a sound barrier window. The resonators may form an integral part of one of the members or may be suspended between the members by netting or sound insulating material.
