This book was released on 2014 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sound localization in the horizontal plane depends on interaural time difference (ITD) and interaural level difference (ILD) cues, which are both available in wideband sounds. Previous studies have directly measured listener weighting of those cues only under quiet, anechoic conditions, but not in the presence of noise and reverberation, which can degrade both ITD and ILD. This study examined the effects of changes in target spectral profile, background noise, and reverberation on sound localization performance and cue weighting strategies. Listeners reported locations of targets that were presented over headphones in virtual auditory space. ITD and ILD were manipulated by attenuating or delaying the sound at one ear, and their weighting was computed by comparing the listener's localization response bias to the imposed cue bias. Results suggest that ITD dominates for any wideband target in quiet conditions, but that listeners increase their weighting of ILD in more adverse listening conditions.

Book Synopsis Binaural Hearing by : Ruth Y. Litovsky
Download or read book Binaural Hearing written by Ruth Y. Litovsky and published by Springer Nature. This book was released on 2021-03-01 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of Binaural Hearing involves studies of auditory perception, physiology, and modeling, including normal and abnormal aspects of the system. Binaural processes involved in both sound localization and speech unmasking have gained a broader interest and have received growing attention in the published literature. The field has undergone some significant changes. There is now a much richer understanding of the many aspects that comprising binaural processing, its role in development, and in success and limitations of hearing-aid and cochlear-implant users. The goal of this volume is to provide an up-to-date reference on the developments and novel ideas in the field of binaural hearing. The primary readership for the volume is expected to be academic specialists in the diverse fields that connect with psychoacoustics, neuroscience, engineering, psychology, audiology, and cochlear implants. This volume will serve as an important resource by way of introduction to the field, in particular for graduate students, postdoctoral scholars, the faculty who train them and clinicians.
Book Synopsis Virtual Sound Localization Using Head Related Transfer Functions Modified in the Spectral Modulation Frequency Domain by :

This book was released on 2005 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sound localization cues generally include interaural time difference (ITD), interaural intensity difference (IID) and spectral cues. The purpose of this study is to investigate the important spectral cues involved in so-called head related transfer functions (HRTFs) using a combination of HRTF analyses and a virtual sound localization (VSL) experiment. One of the advantages of VSL is that it allows one to manipulate different cues systematically, and sound stimuli used in VSL can be synthesized in a well controlled way. Previous investigations have shown that HRTFs vary greatly among different subjects and that performance in VSL tasks using randomly selected, non-individualized HRTFs is considerably worse than performance with individualized HRTFs. An efficient procedure for HRTF customization and subject training in a VSL task were developed in the present study to improve the VSL performance using non-individualized HRTFs. The HRTF customization procedure combined both subjective and objective evaluation methods. The overall virtual localization accuracy (in the baseline condition) of all of our subjects was higher than that reported by studies using non-individualized HRTFs. The individually customized HRTFs were used for further investigation of the spectral cues in sound localization. Previous psychoacoustical and physiological studies have both suggested the existence of spectral modulation frequency (SMF) channels for analyzing spectral information (e.g. the spectral cues coded in HRTFs). SMFs are in a domain related to the Fourier transform of HRTFs. The relationship between various SMF regions and sound localization was tested here by filtering or enhancing HRTFs in the SMF domain under a series of conditions using a VSL experiment. Present VSL results revealed that azimuth localization was not significantly affected by HRTF manipulation. Applying notch filters between 0.1 and 0.4 cycles/octave or between 0.35 and 0.65 cycles/octave resulted in significantly less accurate elevation responses at low elevations, while spectral enhancement in these two SMF regions did not produce a significant change in sound localization. Likewise, lowpass filtering at 2 cycles/octave did not significantly influence localization accuracy, suggesting that the major cues for sound localization are in the SMF region below 2 cycles/octave. Together, these results highlight the relationship between SMF region and sound localization in the vertical plane. These results also confirm and extend previous attempts at optimizing the use of non-individualized HRTFs in VSL. Knowledge of the influence of manipulations in the SMF domain on sound localization has implications for the application of various signal processing algorithms and models of monaural and binaural hearing.

Available in PDF, EPUB and Kindle. Book excerpt: The Sense of Hearing is a truly accessible introduction to auditory perception that is intended for students approaching the subject for the first time, and as a foundation for more advanced study. The second edition has been thoroughly revised throughout, and included new chapters on music, hearing impairment, and a new appendix describing research methodologies. In clear and authoritative prose, the fundamental aspects of hearing are addressed. The reader is introduced to the nature of sound and the spectrum, and the anatomy and physiology of the auditory system. Basic auditory processes including frequency selectivity, loudness and pitch perception, temporal resolution, and sound localization are explained. The reader is led to an understanding of the remarkable abilities of the auditory system in a systematic and coherent way. In subsequent chapters, it is shown how complex processes, such as perceptual organization, speech perception, and music perception, are dependent on the initial analysis that occurs when sounds enter the ear. Finally, a chapter on hearing impairment provides an introduction to disorders of the auditory system. The text benefits from 162 original illustrations, including uncluttered diagrams that illuminate auditory mechanisms. An extensive glossary provides definitions of technical terms. The emphasis is on explanation and clarity of style throughout, making The Sense of Hearing an essential resource for students and educators involved in this sometimes challenging field.

Book Synopsis Effects of Amplitude Modulation on Sound Localization in Reverberant Environments by : Paul W. Anderson
Download or read book Effects of Amplitude Modulation on Sound Localization in Reverberant Environments written by Paul W. Anderson and published by . This book was released on 2015 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Auditory localization involves different cues depending on the spatial domain. Azimuth localization cues include interaural time differences (ITDs), interaural level differences (ILDs) and pinnae cues. Auditory distance perception (ADP) cues include intensity, spectral cues, binaural cues, and the direct-to-reverberant energy ratio (D/R). While D/R has been established as a primary ADP cue, it is unlikely that it is directly encoded in the auditory system because it can be difficult to extract from ongoing signals. It is also noteworthy that no neuronal population has been identified that specifically codes D/R. It has therefore been proposed that D/R is indirectly encoded in the auditory system, through sensitivity to other acoustic parameters that are correlated with D/R, such as temporal cues (Zahorik, 2002b), spectral properties (Jetzt, 1979; Larsen, 2008), and interaural correlation (Bronkhorst and Houtgast, 1999). An additional D/R correlate relies on attenuation of amplitude modulation (AM) as a function of distance. Room modulation transfer functions act as low-pass filters on AM signals, and therefore the direct portion of a signal will have less modulation depth attenuation than the reverberant portion. Although recent neural and behavioral work has demonstrated that this cue can provide distance information monaurally, the extent to which the modulation attenuation cue contributes to ADP relative to other ADP cues is not fully understood. It is also possible modulation attenuation by the room can provide additional directional localization information, perhaps through the resulting dynamic fluctuation of the ILD cue. The role of AM in directional sound localization has not been extensively studied, particularly in reverberant soundfields which can affect the modulation reaching the two ears in a directionally-dependent fashion. Three human psychophysical experiments assessed the role of AM signals in distance and directional auditory localization in reverberant soundfields. Experiment I focused on validating a graphical response method to be used in subsequent experiments. In Experiment II, an auditory distance estimation task was performed which yielded measures of the relative perceptual contributions of the modulation depth cue during ADP in a reverberant room. Experiment III investigated the effect of AM on binaural localization in the horizontal plane in a reverberant room.
