The process is especially fitting for a microphone comprising silicon nitride dielectric layers with aluminum electrodes.
The sensor has the potential to be used as a universal and low-cost optical microphone.
The microphone effect must presumably be regarded as a necessary link in the perception of sound.
Detailed performance results presented show that the microphone array is superior to a single microphone.<<ETX>>
The results are useful in determining signal-to-noise ratio gains from arbitrarily positioned differential microphone elements in microphone array applications.
The results are also useful in determining signal-to-noise ratio gains from arbitrarily positioned differential microphone elements in microphone array applications.
This research is instructive for comprehensively understanding the mechanism and making full use of the acoustic amplifier.
The results show that a more stable solution is obtained with the proposed two microphone approach.
Experiments proved the effectiveness of the proposed solution in a linear microphone array set up.
