OBJECTIVE Up to now, treatment modalities of unilateral deafness consist of no treatment, conventional contralateral routing of signal (CROS), or Bone-Anchored Hearing Aid (BAHA) hearing aid. Cochlear implantation makes a new treatment modality available for patients with single-sided deafness. The aim of this study is to evaluate the use of unilateral electrical stimulation with normal hearing...

This collection of digitized sound examples was assembled for Acta Acustica to illustrate some interesting and important spatial hearing phenomena. The examples are grouped as follows:

With increasing numbers of children and adults receiving bilateral cochlear implants, there is an urgent need for assessment tools that enable testing of binaural hearing abilities. Current test batteries are either limited in scope or are of an impractical duration for routine testing. Here, we report a behavioral test that enables combined testing of speech identification and spatial discrimi...

This thesis concerns a new zero-crossing-based binaural model for spatial hearing. Conventional binaural model computes cross-correlations of binaural signals for the estimation of the interaural time difference which is a primary spatial cue. However, the cross-correlationbased binaural processing model requires high computational complexity and suffers from inaccuracies in localizing sound so...

PURPOSE The use of bilateral stimulation is becoming common for cochlear implant (CI) recipients with either (a) a CI in one ear and a hearing aid (HA) in the nonimplanted ear (CI&HA-bimodal) or (b) CIs in both ears (CI&CI-bilateral). The objective of this study was to evaluate 4 individuals who transitioned from bimodal to bilateral stimulation. METHOD Participants had completed a larger stu...

OBJECTIVE Spatial release from masking (SRM) can increase speech intelligibility in complex listening environments. The goal of the present study was to document how speech-in-speech stimuli could be best processed to encourage optimum SRM for listeners who represent a range of ages and amounts of hearing loss. We examined the effects of equating stimulus audibility among listeners, presenting ...

Deafness affects ∼2 in 1000 children and is one of the most common congenital impairments. Permanent hearing loss can be treated by fitting hearing aids. More severe to profound deafness is an indication for cochlear implantation. Although newborn hearing screening programs have increased the identification of asymmetric hearing loss, parents and caregivers of children with single-sided deafnes...

Early binaural experience can recalibrate central auditory circuits that support spatial hearing. However, it is not known how binaural integration matures shortly after hearing onset or whether various developmental stages are differentially impacted by disruptions of normal binaural experience. Here we induce a brief, reversible unilateral conductive hearing loss (CHL) at several experimental...

Spatial acoustics constitute a major part of our experience of the world. The ability to make sense of our environment depends on spatial awareness and hearing plays a major role in this process. Yet in videogames, the acoustic information available to us is reduced. This cripples our hearing, leaving spatial awareness dependant on vision alone. This thesis examines the problems surrounding the...
