Abstract

Lavandier and Culling [Lavandier, M. and Culling, J. F. 2010. Prediction of binaural speech intelligibility against noise in rooms. J. Acoust. Soc. Am. 127, 387-399] demonstrated a method of predicting human speech reception thresholds for speech in combined noise and reverberation. An updated version of the model is presented, which is substantially more computationally efficient. The updated model makes similar predictions for the SRT data considered by Lavandier and Culling, which tested the model's ability to predict effects of binaural unmasking and room colouration. In addition, we show here that the model accurately predicts the effects of headshadow and reproduces a range of data sets from the literature, including situations with multiple interfering sounds in anechoic conditions.

摘要

拉凡迪耶（Lavandier）和卡林（Culling）[Lavandier, M. and Culling, J. F. 2010. Prediction of binaural speech intelligibility against noise in rooms. J. Acoust. Soc. Am. 127, 387-399]展示了一种预测人在噪声和混响环境下的双语音听辨阈限的方法。本文提出了该模型的一个更新版本，它的计算效率显著提高。更新后的模型对拉凡迪耶和卡林所考虑的 SRT 数据进行了类似的预测，这些数据测试了该模型预测双耳掩蔽和房间混响效果的能力。此外，我们还展示了该模型能够准确预测阴影效应，并再现了一系列文献中的数据集，包括在消声环境中存在多个干扰声音的情况。
