Abstract
An 128 element acoustic array utilizing digital MEMS microphones was developed for demonstrating Artificial Intelligence techniques in an Acoustic Sensor System. The data from all 128 elements are collected and transmitted to the host computer through USB at a bit depth of 24 bit and sample rate of 48 kHz. Under the assumption of a condition of limited processing power, Artificial Intelligence techniques are used to determine the optimum choice of which set of 24 of the available 128 elements to process for determining the direction of a detected source of sound. The design and construction of the array will be discussed. A companion presentation will discuss the signal processing techniques developed and employed on the system.
