The lack of the auditory sense in the hearing-impaired raises the question as to the extent to which this deficiency affects their cognitive and intellectual skills. Studies have pointed out, that with regard to reasoning, particularly when the process of induction is required, hearing-impaired children usually have difficulties. They experience similar difficulties with their ability to think ...

Purpose: This study examined the spatial separation benefit (SSB) and fluctuating masker (FMB) for sentence-in-noise recognition in normal-hearing (NH) hearing-impaired (HI) listeners.Methods: Twenty NH listeners 10 HI who were regular hearing-aid wearers participated this study. To measure SSB FMB, Korean Matrix scores obtained using different types of noise (steady-state speech-shaped noise, ...

HYPOTHESIS In children with bilateral cochlear implants (BiCIs), experience over a 1 to 3-year period can improve speech understanding and spatial unmasking of speech. BACKGROUND One reason for providing children with BiCIs is to improve spatial hearing abilities. Little is known about changes in performance with added bilateral experience, and the relation between sound localization and spat...

Human listeners are able to concentrate on listening to one voice amidst other conversations and background noise, but not all of the neural mechanisms for this process are understood. There is growing evidence in normal-hearing subjects that the medial olivocochlear (MOC) auditory efferent system is involved in the detection of signals in noise, such as speech sounds, by modulation of cochlear...

OBJECTIVE To investigate the effect of sensitivity to temporal fine structure (TFS) on subjective measures of hearing aid outcome. DESIGN Prior to receiving hearing aids, participants completed a test to assess sensitivity to TFS and two self-assessment questionnaires; the Glasgow Hearing Aid Benefit Profile (GHABP), and the Speech, Spatial and Qualities of hearing (SSQ-A). Follow-up appointm...

OBJECTIVES Previous studies investigating speech perception in noise have typically been conducted with static masker positions. The aim of this study was to investigate the effect of spatial separation of source and masker (spatial release from masking, SRM) in a moving masker setup and to evaluate the impact of adaptive beamforming in comparison with fixed directional microphones in cochlear ...

Evaluation of the speech, spatial and qualities hearing in unilateral bimodal cochlear implant users with incomplete partition type II Objective: The aim this study was to perform a scale-based assessment abilities IP malformation normal cochlea, including discrimination, orientation, positioning speech environmental sounds their environment. Material Methods: A total 30 users, 15 participants ...

PURPOSE To compare the ability of the auditory brainstem response to complex sounds (cABR) to predict subjective ratings of speech understanding in noise on the Speech, Spatial, and Qualities of Hearing Scale (SSQ; Gatehouse & Noble, 2004) relative to the predictive ability of the Quick Speech-in-Noise test (QuickSIN; Killion, Niquette, Gudmundsen, Revit, & Banerjee, 2004) and pure-tone hearing...

One hundred volunteers have undergone short (5 min) listening tests in a novel multitransducer bone-and-tissue conduction apparatus for spatial audio. The subjects subsequently described their experiences in an unstructured qualitative elicitation exercise. Their responses were aggregated to identify key themes and differences. Emergent themes are: enjoyable, informative, spatial and strange. T...

Large individual differences are relatively common in human perception. Spatial hearing is not an exception; for instance, two listeners can perceive the same auditory target to be at very different spatial locations. Such variability cannot be considered as mere experimental noise but as true data that we have to use for explaining the mechanisms underlying the perception of auditory space. Th...
