Description

Technical Field

[0001] The present invention belongs to the technical field of preformed solder sheet production, and in particular relates to an audiometer attenuator control method and system. Background Art

[0002] An audiometer, a core device for assessing hearing function, uses its attenuator to measure hearing thresholds by adjusting signal strength, making it a critical component for test accuracy. Current mainstream audiometer attenuator control systems commonly suffer from the following technical bottlenecks: Traditional control schemes rely on a single processing module to perform signal analysis and strategy generation, lacking refined functional division. This results in incomplete signal preprocessing, weak environmental interference suppression, and inability to cope with the impact of complex electromagnetic environments or temperature and humidity fluctuations on attenuation accuracy. For example, analog attenuators are susceptible to mechanical wear and temperature drift, while digital attenuators suffer from poor signal format compatibility. Both systems share the common issues of cumbersome manual adjustment steps and a single automatic adjustment algorithm (supporting only fixed-step attenuation), making them unable to meet personalized testing needs (such as low-stimulus threshold adjustment for children or precise compensation for high-frequency hearing loss). Furthermore, existing systems generally lack real-time feedback loops and fault self-diagnosis mechanisms. Instead of monitoring attenuation through a single sensor, error correction lags and a high false positive rate (the industry average error is >1dB). This makes it difficult to provide timely warnings for faults such as poor contact and motor stalling, resulting in reduced test data reliability.

[0003] Furthermore, issues such as a single human-computer interaction method (physical buttons only), reliance on an external computer for test report generation, and a lack of mobile power management support have made traditional devices less adaptable in distributed applications such as in-vehicle testing and community screening. As hearing testing expands from clinical diagnosis to early screening and rehabilitation assessment, the market demand for attenuator control that is more precise (error ≤ 0.5dB), intelligent (automatically adapting to hearing loss types), and convenient (multimodal interaction and offline battery life) is becoming increasingly urgent.

[0004] Due to defects such as low module integration, poor algorithm adaptability, and insufficient reliability, existing technologies are unable to meet the requirements of efficient detection of new audiometers in complex scenarios. It is urgent to achieve a comprehensive improvement in attenuator control performance through systematic module innovation and control method optimization. Summary of the Invention
