A Listening Test System for Automotive Audio: PART 5—The Influence of Listening Environment on the Realism of Binaural Reproduction
Binaural technology is used to capture elements of an in-car sound field and reproduce them over headphones. An experiment to test the influence of the listening environment on the realism of such a binaural reproduction is described. A panel of 12 trained listeners rated a range of stimuli for 6 elicited attributes of sound quality. Ratings are made for the actual sound field in the test vehicle, for a binaural reproduction in the same vehicle and for a binaural reproduction in a listening room. The results show that the tested binaural reproduction system is able to preserve the perceived impressions of the sound field for the attributes Precision, Treble, Stereo impression, Bass, and Reverberation, independent of the listening environment.
