Acoustic Pattern Recognition for Security Breaching Noise Detection Navy STTR FY2006 Sol No.: Navy STTR FY2006 Topic No.: N06-T036 Topic Title: Acoustic Pattern Recognition for Security Breaching Noise Detection Proposal No.: N064-036-0132 Firm: Advanced Acoustic Concepts Incorporated 425 Oser Avenue Hauppauge, New York 11788 Contact: John Pinezich Phone: (631) 273-5700 Web Site: www.aactech.com Abstract: This proposal addresses new technologies to enhance the security of assets in fixed bases or field operations by early acoustic recognition of threats such as sniper fire and rocket propelled grenade attacks, for security breaching noises out of line of sight amidst high noise. The proposed work will extend the proven capabilities of Advanced Acoustic Concepts' (AAC) sparsely populated volumetric array (SPVA) technology for detecting and localizing sounds, combined with the auditory cortex (AC) model of sound recognition and classification developed at the University of Maryland, to security breaching noises, including gunshot sounds, RPG/mortar firings, and sniper detection. This will capitalize on AAC's Navy-proven technology for sound localization by adapting the SPVA software, together with expertise at the University of Maryland in the design of biologically inspired sound processing, and apply them to broadband impulsive noises. The work will include assembling a data base of security breaching noises of interest, and exercising the software model on the data base to determine the feasibility of a platform that can be trained to identify and localize sounds in a high-noise environment from sources out of the line of sight. Benefits: An acoustic recognition platform capable of identifying and localizing security breaching noises out of line of sight in a high noise environment will provide early proactive alerts that can activate other verification and prevention technologies. Early acoustic recognition will enable a more timely comprehensive response with enhanced ability to nullify threats. In addition to battlefield and perimeter security for military assets, other potential applications include border security (the Secure Border Initiative of the Department of Homeland Security). Private sector applications include protection of high-risk facilities and critical infrastructure perimeters. Return
