Abstract
A system for detecting and monitoring blast noise, the invention provides ncentrically arranged cylindrical windscreens having a pair of vertically spaced microphones mounted centrally therein, the windscreens acting to reduce interference from wind-generated pseudosound yet being acoustically transparent so as not to interfere with the reception of acoustical data incident on the microphones. The present system also includes a signal processing subsystem which receives the output of the respective microphones for analysis.
