Abstract:
A noise monitoring system has at least two microphones and a microphones sensitivity register. The microphones are arranged physically with respect to each other such that when the microphones are placed within an acoustic field to be monitored, the RMS signal level of that acoustic field at each of the microphones is substantially the same for a monitoring frequency range. The microphones sensitivity register has reference data indicative of an initial sensitivity difference (Δ 0 ) between output RMS signal levels measured by the microphones in a reference acoustic field. A current difference (Δ 1 , Δ 2 ) between the RMS signal levels concurrently output by the microphones for the currently monitored acoustic field is compared. A fault signal is generated if the current difference (Δ 1 , Δ 2 ) differs from the initial sensitivity difference (Δ 0 ) more than an acceptable limit.

Claim (Index 7):
A method for checking of a microphone condition in a noise monitoring system that includes at least two microphones arranged physically with respect to each other such that when the microphones are placed within an acoustic field to be monitored, the root mean square (RMS) signal level of that acoustic field at each of the microphones is substantially the same for a monitoring frequency range, and a microphones sensitivity register that includes reference data indicative of an initial sensitivity difference (\u03940) between output RMS signal levels measured by the microphones in a reference acoustic field, the method comprising:\n comparing a current difference (\u03941, \u03942) between the RMS signal levels concurrently output by the microphones for the currently monitored acoustic field and generating a fault signal if the current difference (\u03941, \u03942) differs from the initial sensitivity difference (\u03940) more than an acceptable limit, wherein the differences (\u03940, \u03941, \u03942) between the RMS signal levels are analyzed individually for a plurality of narrow band signals.
