CERL Noise Monitoring and Warning System 98.

Abstract

The present CERL Noise Monitoring and Warning System, designed in the mid-1980s, has difficulty separating blast noise sounds from wind-induced pseudonoise. A new noise monitor was designed that would be more wind noise resistant and would use more modern electronics and methods than those available in 1985. This report documents the design and construction of this new noise monitor. The heart of wind-noise resistance is a two- microphone array and special signal processing to identify and separate blast sounds from pseudo- wind noise. The results are quite encouraging. it appears that the new monitor improves the signal-to-noise ratio by about 10 dB. It is recommended that this monitor be transferred to the field by a demonstration validation program such as the Environmental Security Technology Certification Program (ESTOP).
