摘要：

Head orientation (HO) affects better-ear-listening and spatial-release-from-masking, which are two key aspects in binaural speech intelligibility. To incorporate HO in speech intelligibility prediction, binaural room impulse responses (BRIRs) for every HO of interest could be used. Due to the limited spectral bandwidth of speech, however, approximate representations might be sufficient, which can be measured more quickly. A comparison was done between pseudo-BRIRs generated with a motion tracked binaural microphone array and a first order Ambisonics microphone using the spatial decomposition method (SDM). The accuracy of the Ambisonics/SDM approach was comparable to that of real BRIRs, indicating its suitability for speech intelligibility prediction. (C) 2019 Acoustical Society of America
