A sound focusing mechanism for generating a focused source of sound which can , be used to identify the transmission loss of an object or identify areas of acoustic leakage is disclosed. The sound focusing mechanism includes a housing having at least one wall formed from a material having high sound insulating properties. A sound generating device for generating a sound is located within a central cavity within the housing. An actuator assembly is operatively connected to the sound generating device for selectively operating the sound generating device. The wall is configured to limit the transmission of the sound there through such that a focused beam or pulse sound is emitted from …

Why it's free to use
- Filed June 18, 2004 and granted February 19, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 18, 2024.
