A Note on Establishing Reliable Bone Conduction Thresholds with In-Noise Data (Data & Graphs).xlsx

The current research data presents a method of establishing reliable bone conduction absolute hearing thresholds with the presence of in-noise data. Hearing sensitivity (AC closed-ear and BC open-ear without occlusion) was measured from six normal hearing listeners using pure tone signals without masking, narrowband noise signals without masking, and narrowband noise signals with masking at three skull contact locations using the Radioear B81, B71W, and B71 over the range of five audible frequencies. Results indicate that the in-noise testing procedure used in this study allows for reliable determination of bone-conduction thresholds. No significant auditory leakage was observed in case of any of the three devices used and the bone-conduction thresholds determined in-noise and in-quiet conditions were well aligned. This applies to both the pure-tone and narrow-band noise determined thresholds.本研究相关数据集提出了一种可在存在噪声数据的场景下构建可靠骨传导绝对听阈（bone conduction absolute hearing thresholds）的方法。研究针对6名听力正常受试者，采用无掩蔽纯音信号、无掩蔽窄带噪声信号及带掩蔽窄带噪声信号，使用Radioear B81、B71W与B71三款测试设备，在3种颅骨接触位置下，于5个可听频率（audible frequencies）区间内测试其听力敏感度，测试涵盖气导（Air Conduction, AC）闭耳测试与开放耳骨导（Bone Conduction, BC）测试（无耳罩遮挡）。研究结果表明，本研究所采用的噪声环境测试流程可实现骨传导听阈的可靠测定。三款受试设备均未出现显著的听觉漏声（auditory leakage）现象，且噪声环境与静息环境下测得的骨传导听阈具有良好的一致性，该结论适用于纯音及窄带噪声两种测试方式下得到的听阈结果。
