借助声学头模考察了水平面不同语声源和噪声源位置对语言清晰度测量的影响,比较了有声学头模的双耳STIPA与无声学头模常规STIPA测量结果的差异,分别采用录听和现场测听方式进行了同等条件下的汉语听感清晰度主观评价实验,并分析了清晰度主客观结果的相关性。结果表明:声源位置对有声学头模的STIPA以及头模录制信号和真人现场实测的听感清晰度影响显著。无声学头模的STIPA更接近有声学头模时左右耳中较差的劣势耳的STIPA结果。单侧耳与语声源同侧或与噪声源异侧对应的单侧耳听感清晰度更高,语声源和噪声源重叠对应的双耳听感清晰度最低,声源分离可以显著提高双耳听感清晰度。头模录制信号和真人现场实测的听感清晰度与无声学头模STIPA不相关,与有声学头模的STIPA高度相关,其中单侧耳听感清晰度与该单侧耳STIPA高度相关,双耳听感清晰度与左右耳STIPA的较高值相关性最高。
The effects of different language sources and noise sources on speech intelligibility measurement were investigated by means of acoustical head-mold. The differences between conventional STIPA with acoustical head mode and conventional STIPA with headless mode were compared. On-site audiometry conducted a subjective evaluation of Chinese listening sense under the same conditions, and analyzed the relevance of the subjective and objective results of clarity. The results show that the position of the sound source has a significant influence on the STIPA of the acoustic head module and the recorded signal of the head module and the actual sense of hearing of the live scene. The STIPA of the silent head module is closer to the STIPA result of the poor inferior ear around the acoustic head module. Single-sided ear and the sound source ipsilateral or noise source corresponding to the opposite side of the unilateral ear higher sense of hearing, the sound source and noise source overlap corresponds to the lowest sense of hearing the ears, sound source separation can significantly improve the ears Listen to the sense of clarity. Headstrings recorded signal and real field auditory clarity and silent head mode STIPA irrelevant, and the acoustic head mode STIPA highly correlated, which unilateral ear hearing sense and the unilateral ear STIPA highly correlated, both ears Sensitivity was highest correlated with higher values of left and right ear STIPA.
