AI Technical Summary
Existing otoacoustic emission detection equipment suffers from poor portability, weak anti-interference capabilities, simple signal preprocessing, complex operation, and insufficient battery life, making it difficult to meet the needs of primary healthcare, home health monitoring, and outdoor emergency scenarios.
The otoacoustic emission signal detection system adopts a modular architecture, including signal transmission, reception, processing, interaction and low power supply modules. Combined with adaptive filtering, multimodal preprocessing, dynamic noise source classification and spatiotemporal multi-scale feature fusion network, it can achieve high-precision signal detection and convenient operation.
The system's size and weight have been significantly reduced, the signal-to-noise ratio has been improved by 45%, the detection accuracy has been comprehensively optimized, the sensitivity of high-frequency damage detection has been improved by 40%, and the detection rate of early noise-induced hearing loss has been increased by 32%, meeting the detection needs of non-quiet environments.
