Orduña-Bustamante Ingeniería noise correlation reverberation binaural sound interaural cross Subjective tests were carried out in order to investigate speech intelligibility, and the possiblerelative improvements that can be obtained in practical applications to acoustic communication systems, for different forms of presentationthrough headphones: monaural, monophonic, binaural at 0º (in front of the listener) and binaural at ±30º (right or left, relative to the listener), played back undisturbed, and also with the addition of extreme levels of disturbing noise and reverberation, with a signal to noise ratio of SRN = ¿10 DB, and a reverberation time of T60 = 10 s. The influence of interaural cross-correlation (IACC) of the disturbance on speech intelligibility was also studied. Phonetically balancedwords in Spanish, uttered by a female speaker, were used as speech material, which were contaminated with interaurally correlated and uncorrelated noise and reverberation. Results indicate advantages of binaural speechintelligibility under adverse listening conditions; with slight improvements observed when listening under interaurally correlated noise at an angle off-center, for azimuth angles of ±30°, relative to listening at 0º. Additionally, results showthat speech intelligibility improves slightly when the disturbing reverberation has a low interauralcross-correlation (IACC). 2012 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47423208005 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.3 Vol.10 |
