Improved Military Noise Monitoring System

WP-201117

Objective

The objective of this project is to demonstrate that a recently developed military noise monitor with integrated classifiers meets the needs of Department of Defense installations. Validation of this system is a critical last step before commercialization. In particular, the project will validate that the impulse noise Bearing and Amplitude Measurement and Analysis System (BAMAS) can accurately detect and classify military noise sources, properly reject non-military noise sources, and provide near real-time feedback to users in a user-friendly format. The project will also demonstrate that the system is cost efficient in terms of initial cost and annual maintenance and is capable of monitoring a large area/community in outdoor environments.

Technology Description

Applied Physical Sciences Corp. in Groton, Connecticut, and the University of Pittsburgh have developed an improved noise monitoring system called BAMAS for mitigating windborne and other sources of non-military noise. Developed with support from SERDP (WP-1427), the system includes a collection of remote sensors capable of detection, localization, and classification. Each sensor uses an acoustic array and real-time signal processing codes to estimate the noise source location. Mitigation of windborne events is accomplished using cross-channel correlation analysis, beamforming, and a military noise classifier.

Benefits

Noise monitoring is an integral component for sustaining testing and training at military installations. Other blast noise monitoring systems do not accurately detect and classify military noises, are plagued by wind noise resulting in an unacceptable amount of reported false positives, and have an unacceptable high triggering threshold. BAMAS has been developed to specifically remedy each of these constraints and issues. (Anticipated Project Completion - 2014)
