Acoustic Array Processing in High Noise Environments

Microphone arrays have many practical applications in acoustics including both battlefield acoustics and sonic anemometry. These can be used to measure several types of acoustic signals: short-term transients, long-term transients, and coherent stationary signals. With a microphone array, signal processing techniques can be used to increase the signal to noise ratio in high noise environments, and they can also be used to determine the direction of arrival of detected coherent signals. These signal detection and direction of arrival algorithms have broad applications both in and outside of the field of acoustics. This particular talk aims to explore the basics of utilizing a sensor arrays and signal processing techniques in acoustics and the advantages that they provide in high noise environments.
