3 results about "Hearing functions" patented technology

The application discloses an otoacoustic emission signal detection system and method, and belongs to the technical field of hearing function detection. The system adopts a modular architecture and comprises a signal emission module, a signal receiving module, a core processing module, an intelligent interaction module and a low-power supply module. The modules are interconnected through an SPI bus. The method can realize high-precision extraction and analysis of otoacoustic emission signals through a dynamic noise source classification and inhibition algorithm combined with a space-time multi-scale feature fusion network. The application can solve the problems of poor portability, weak anti-interference ability, simple signal preprocessing, complex operation and insufficient endurance of existing devices, realize integrated design of 'high-precision detection + convenient operation + long endurance', and meet the needs of primary medical treatment, family health monitoring and outdoor emergency scenes.
