适用范围/预期用途
用于人耳听力损失的诊断。
一、工作原理（Working Principle）
中文
纯音测听原理采用DSP 数字信号处理生成高精度正弦纯音、啭音（5Hz 调频）、脉冲音，经TDH39/DD45 耳机 / B71 骨导输出；按Hughson-Westlake（升 5 降 10）标准程序，通过患者应答判断听阈，定位传导性 / 感音神经性 / 混合性听力损失。
掩蔽原理测试非测试耳施加窄带噪声（NB）/ 白噪声（WN）/ 言语噪声（SN），防止交叉听力（cross-hearing），确保单耳阈值准确；支持同侧掩蔽（Langenbeck）、双侧同步掩蔽。
言语测听原理内置麦克风 / 预录言语材料，通过耳机 / 声场发放，测试言语识别率（SRT）、最大识别度（WRS），评估言语交流能力。
特殊诊断原理
SISI：短增量敏感指数，鉴别耳蜗病变
ABLB：双耳交替响度平衡，判断重振现象
Stenger：伪聋 / 非器质性听力损失鉴别
Békésy：自描测听，连续频率阈值曲线
Langenbeck：噪声中纯音测试，评估信噪比耐受
English
Pure-Tone Audiometry PrincipleDSP-generatedprecise pure tone/warble/pulse tone; delivered viaTDH39/DD45/B71 bone oscillator; thresholds determined viaHughson-Westlake (up 5dB, down 10dB)per ISO 8253; classifiesconductive/sensorineural/mixedloss.
Masking PrincipleNarrow Band (NB)/White (WN)/Speech (SN) noiseto non-test ear eliminatescross-hearing; supportsLangenbeck (ipsilateral masking)and binaural synchronous masking.
Speech Audiometry PrincipleBuilt-in mic/pre-recorded speech; presented via headphones/soundfield; measuresSRT/WRSto evaluate speech perception.
