It is possible to psychophysically measure the phase and level of bone conducted sound at the cochleae using two bone transducers (BTs) [Mcleod and Culling (2019). J. Acoust Soc. Am. 146, 3295 − 3301]. The present work uses such measurements to improve masked thresholds by using the phase and level values to create a unilateral crosstalk cancellation system. To avoid changes in the coupling of the BT to the head, testing of tone and speech reception thresholds with and without crosstalk cancellation had to be performed immediately following the measurements without adjustment of the BT. To achieve this, a faster measurement method was created. Previously measured phase and level results were interpolated to predict likely results for new test frequencies. Testing time to collect the necessary phase and level values was reduced to approximately 15 min by exploiting listeners' previous measurements. The inter-cochlear phase difference and inter-cochlear level difference were consistent between experimental sittings in the same participant but different between participants. Addition of a crosstalk cancellation signal improved tone and speech reception thresholds for tones/speech presented with one BT and noise presented on the other by an average of 12.1 dB for tones and 13.67 dB for speech.

在正常听力参与者中，使用双侧骨传感器消除单侧串扰。

可以使用两个骨传感器（BT）从心理上测量耳蜗处骨传导声音的相位和水平[Mcleod and Culling（2019）。J. Acoust Soc。上午。146，3295-3301]。本工作通过使用相位和电平值创建单边串扰消除系统，使用此类测量来改善掩蔽阈值。为了避免BT与头部的耦合发生变化，必须在测量后立即进行具有和不具有串扰消除功能的音调和语音接收阈值测试，而无需调整BT。为此，创建了一种更快的测量方法。内插先前测得的相位和电平结果，以预测新测试频率的可能结果。通过利用听众的先前测量，收集必要相位和电平值的测试时间减少到大约15分钟。同一参与者的实验坐位之间，耳蜗之间的相位差和耳蜗之间的水平差是一致的，但是参与者之间的耳蜗之间的相位差和耳蜗之间的水平差是一致的。串扰消除信号的添加使一个BT呈现的音调/语音和另一种呈现的噪声的音调和语音接收阈值平均提高了12.1 dB（语音）和13.67 dB（语音）。
