Book Description
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.

Abstract: Binaural speech recognition abilities in a group of young adults with normal hearing were analyzed through dichotic listening and word recognition in noise tasks. Dichotic listening was tested under three conditions: free-recall, directed right, and directed left. Word recognition in noise was also tested under three conditions: binaural, monaural right, and monaural left. For the dichotic listening task, subjects exhibited a small right ear advantage (REA) under the free-recall condition, an even larger REA under the directed right condition, and a small left ear advantage (LEA) under the directed left condition. For the words in noise task, subjects exhibited similar scores for the binaural and monaural left conditions; monaural right scores were slightly worse. Results were compared to older adult data previously gathered for both dichotic listening (Roup et al., 2006) and word recognition in noise (Wilson, 2003) tasks. While the young adults exhibited a REA in the free-recall condition, the older adults exhibited an even greater REA. This suggests that there is an age related change in auditory processing that interferes with the ability to integrate the signals entering both ears in dichotic situations. For the words in noise task, both groups did worse as the signal-to-noise ratio decreased. However, young adults scored significantly better than the older adults overall. This suggests that younger adults are better able to separate a signal from background noise than older adults.

Book Description
This book reports on the application of advanced models of the human binaural hearing system in modern technology, among others, in the following areas: binaural analysis of aural scenes, binaural de-reverberation, binaural quality assessment of audio channels, loudspeakers and performance spaces, binaural perceptual coding, binaural processing in hearing aids and cochlea implants, binaural systems in robots, binaural/tactile human-machine interfaces, speech-intelligibility prediction in rooms and/or multi-speaker scenarios. An introduction to binaural modeling and an outlook to the future are provided. Further, the book features a MATLAB toolbox to enable readers to construct their own dedicated binaural models on demand.

Book Description
Hearing is dependent on neural processing of acoustic cues obtained by the left and right ears. Neural signals driven by the two ears are integrated at multiple levels of the central auditory system, which enables animals including humans to perform various functions including localization of a sound source. A natural listening environment typically contains sounds from multiple sources. These sounds can have different spectral and temporal features and occur at either the same or different time. Integration can happen among neural signals elicited by the same or different sounds. The way of integration can greatly affect how individual sounds are sensed and perceived. Functions such as auditory grouping and stream segregation, which are central to establishing coherent auditory images in a complex listening environment, are highly dependent on the way of integration. Binaural hearing is complicated by individual differences and developmental changes in head and pinna shape/size as binaural cues can be affected by these differences and changes. Furthermore, neural processing of binaural cues can be influenced by hearing impairments and the use of hearing aids and cochlear implants. These factors likely require a listener to optimize the use of binaural cues through learning and to use plastic changes in the nervous system to perform the optimization. Great strides have been made in understanding binaural processing in normal and impaired auditory systems. This Research Topic aims to highlight some of the latest findings in the following areas: 1) Animal behavioral and human psychoacoustical studies of binaural hearing; 2) Neural encoding and processing of binaural cues and structural as well as neurophysiological bases of such encoding and processing; 3) Contribution of binaural neural processing to auditory functions such as sound-source localization, binaural fusion, binaural interference, spatial release from masking, auditory grouping, and auditory stream segregation; 4) Computational models of binaural processing; 5) Learning and plastic changes in binaural processing following hearing loss or alterations of acoustic environment and structural as well as physiological bases of these behavioral changes; 6) Clinical aspects of binaural processing including application of processing strategies, including research on the benefits of bilateral cochlear implantation, and the neural correlates thereof

Book Description
We also consider how the computational goal of CASA-based segregation should be defined in reverberant environments. The ideal binary mask (IBM) has been established as a main goal of CASA. While the IBM is defined unambiguously in anechoic conditions, in reverberant environments there is some flexibility in how one might define the target signal itself and therefore, ambiguity is introduced to the notion of the IBM. Due to the perceptual distinction between early and late reflections, we introduce the reflection boundary as a parameter to the IBM definition to allow target reflections to be divided into desirable and undesirable components. We conduct a series of intelligibility tests with normal hearing listeners to compare alternative IBM definitions. Results show that it is vital for the IBM definition to account for the energetic effect of early target reflections, and that late target reflections should be characterized as noise.
