Introduction 1.1. Sound source localization and HRTFs In real environments, wave radiated by sound sources propagates to a listener by direct and reflected paths. The scattering, diffraction and reflection effect of the listener’s anatomical structures (such as head, torso and pinnae) further disturb the sound field and thereby modify the sound pressures received by the two ears. Human hearing comprehen‐ sively utilizes the information encoded in binaural pressures and then forms various spatial auditory experiences, such as sound source localization and subjective perceptions of environmental reflections. Psychoacoustic experiments have proved that the following cues encoded in the binaural pressures contribute to directional localization [1]: 1. The interaural time difference (ITD), i.e., the arrival time difference between the sound waves at left and right ears, is the dominant directional localization cue for frequencies approximately below 1.5 kHz. 2. The interaural level difference (ILD), i.e., the pressure level difference between left and right ears caused by scattering and diffraction of head etc., is the important directional localization cue for frequencies approximately above 1.5 kHz. 3. The spectral cues encoded in the pressure spectra at ears, which are caused by the scattering, diffraction, and reflection of anatomical structures. In particular, the pinna- caused high-frequency spectral cue above 5 to 6 kHz is crucial to front-back disambiguity and vertical localization. © 2014 The Author(s).

The former focuses on items like the recruitment phenomenon, the speech intelligibility of hearing-impaired persons, or just on the question of hearing comfort. Concerning these subjects, different algorithms intending to improve the hearing ability are presented in this paper. These are automatic gain controls, directional microphones, and noise reduction algorithms. Besides the audiological point of view, there are several purely technical problems which have to be solved. An important one is the acoustic feedback. Another instance is the proper automatic control of all hearing aid components by means of a classification unit. In addition to an overview of state-of-the-art algorithms, this paper focuses on future trends.

  • Bimodal Hearing Or Bilateral Cochlear Implants: a Review of the Research Literature
    Bimodal Hearing or Bilateral Cochlear Implants: A Review of the Research Literature Carol A. Sammeth, Ph.D.,1,2 Sean M. Bundy,1 and Douglas A. Miller, M.S.E.E.3 ABSTRACT Over the past 10 years, there have been an increasing number of patients fitted with either bimodal hearing devices (unilateral cochlear implant [CI], and hearing aid on the other ear) or bilateral cochlear implants. Concurrently, there has been an increasing interest in and number of publications on these topics. This article reviews the now fairly voluminous research literature on bimodal hearing and bilateral cochlear implantation in both children and adults. The emphasis of this review is on more recent clinical studies that represent current technology and that evaluated speech recognition in quiet and noise, localization ability, and perceived benefit. A vast majority of bilaterally deaf subjects in these studies showed benefit in one or more areas from bilateral CIs compared with listening with only a unilateral CI. For patients who have sufficient residual low-frequency hearing sensitivity for the provision of amplification in the nonimplanted ear, bimodal hearing appears to provide a good nonsurgical alternative to bilateral CIs or to unilateral listening for many patients.

Copyrighted material. implants, binaural hearing Learning Outcomes: As a result of this activity, the participant will be able to (1) compare possible benefits of bimodal hearing versus bilateral cochlear implantation based on current research, and (2) identify when to consider fitting of bimodal hearing devices or bilateral cochlear implants.

THE USE OF HEAD-AND-TORSO MODELS FOR IMPROVED SPATIAL SOUND SYNTHESIS V. Ralph Algazi1, Richard O. Duda1, and Dennis M. Thompson1 1CIPIC Interface Laboratory, University of California, Davis CA, 95616-8553, USA Correspondence should be addressed to Richard O. Duda ([email protected]) ABSTRACT This paper concerns the use of a simple head-and-torso model to correct de¯ciencies in the low-frequency behavior of experimentally measured head-related transfer functions (HRTFs). This so-called \snowman" model consists of a spherical head located above a spherical torso. In addition to providing improved low- frequency response for music reproduction, the model provides the major low-frequency localization cues, including cues for low-elevation as well as high-elevation sources. The model HRTF and the measured HRTF can be easily combined by using the phase response of the model at all frequencies and by \cross-fading" between the dB magnitude responses of the model and the measurements.

CCC- A UTHSC - KNOXVILLE, TN MANAGEMENT CHALLENGES IN PEDIATRIC UHL Will intervention delay have irreversible consequences to a child with UHL? Is there a way to know a priori that a child with UHL will experience academic failure or binaural deprivation in a way that affects daily living activities? Does the implementation of a holistic UHL evaluation protocol help in determining appropriate outcomes for children with unilateral hearing loss? PREVALENCE OF PEDIATRIC UHL • Prevalence of UHL is of the order of 1 in 1000 in neonates, but increases to as high as 1–5% in school-aged children, though reports vary widely (Boyd 2015; Gordon et al., 2015). • Data on severity of hearing losses are generally lacking, but the proportion of severe- profound cases is probably around 30–50%. • The majority of cases have a genetic origin or are from perinatal complications, but include some acquired losses (largely from meningitis, head trauma, and viral infections) in older children. • A significant proportion of children with severe/profound UHL have sensorineural deafness due to structural abnormalities of the cochlea and IAC (reportedly between 29 and 67%), and a smaller number have outer and middle ear malformations with severe conductive hearing loss. • Newborn hearing screening programs have decreased the age at diagnosis of hearing loss. When hearing loss occurs in only 1 ear, the screening result may be overlooked or dismissed as unimportant, particularly when hearing in the opposite ear is normal (Gordon et al., 2015).

  • Chronic Monaural Sound Localization
    The Journal of Neuroscience, April 28, 2004 • 24(17):4163–4171 • 4163 Behavioral/Systems/Cognitive Contribution of Head Shadow and Pinna Cues to Chronic Monaural Sound Localization Marc M. Van Wanrooij and A. John Van Opstal Department of Medical Physics and Biophysics, University of Nijmegen, 6525 EZ Nijmegen, The Netherlands Monaurally deaf people lack the binaural acoustic difference cues in sound level and timing that are needed to encode sound location in the horizontal plane (azimuth). It has been proposed that these people therefore rely on spectral pinna cues of their normal ear to localize sounds. However, the acoustic head-shadow effect (HSE) might also serve as an azimuth cue, despite its ambiguity when absolute sound levels are unknown. Here, we assess the contribution of either cue in the monaural deaf to two-dimensional (2D) sound localization. In a localization test with randomly interleaved sound levels, we show that all monaurally deaf listeners relied heavily on the HSE, whereas binaural control listeners ignore this cue. However, some monaural listeners responded partly to actual sound-source azimuth, regard- less of sound level. We show that these listeners extracted azimuth information from their pinna cues. The better monaural listeners were able to localize azimuth on the basis of spectral cues, the better their ability to also localize sound-source elevation. In a subsequent localization experiment with one fixed sound level, monaural listeners rapidly adopted a strategy on the basis of the HSE. We conclude that monaural spectral cues are not sufficient for adequate 2D sound localization under unfamiliar acoustic conditions. Thus, monaural listeners strongly rely on the ambiguous HSE, which may help them to cope with familiar acoustic environments.
