Abstract:
1. A method of determining the sound transmission loss of an object, comprising: generating and directing a source of focused sound having a predetermined decibel level on the object such that the transmission of sound is substantially localized on the object; measuring the decibel level of sound after the sound interacts with the object; and comparing the predetermined decibel level to the measured decibel level to determine the transmission loss; wherein the directing occurs at a plurality of locations on the object such that the transmission of sound is substantially localized on each of the plurality of locations on the object; and the measuring occurs at a plurality of corresponding locations on the object; and wherein the source of focused sound is generated by a sound focusing mechanism whereby the sound focusing mechanism comprises: a housing, wherein the housing includes at least one wall which defines a central cavity, wherein one end of the housing having an opening formed therein; a sound generating device for generating a sound is located within the central cavity; and an actuator assembly operatively connected to the sound generating device for selectively operating the sound generating device, wherein the wall limits the transmission of the sound generated by the sound generating device such that the focused sound is emitted from the sound focusing mechanism through the opening.
