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.
