摘要

In this paper we describe an online system for real-time detection of common failure modes of arrays of MEMS microphones. We describe a system with a specific focus on reduced computational complexity for application in embedded microprocessors. The system detects deviations in long-term spectral content and microphone covariance to identify failures whilst being robust to the false negatives inherent in a passively driven online system. Data collected from real degraded microphones show that we can achieve high rates of failure detection.
