This article investigates the different acoustic signals that hearing aid users are exposed to in their everyday environment. Binaural microphone signals from recording positions close to the microphone locations of behind-the-ear hearing aids were recorded by 20 hearing aid users during daily life. The recorded signals were acoustically analyzed with regard to narrowband short-term level distr...

A. Member has bilateral severe to profound sensorineural hearing loss determined by a pure tone average of 70 dB or greater at 500 Hz, 1000 Hz, and 2000 Hz; and B. Member has limited benefit from appropriately fitted binaural hearing aids. Limited benefit from amplification is defined by test scores of 40 % correct or less in best-aided listening condition on open-set sentence cognition (e.g., ...

Hearing loss during development leads to central deficits that persist even after the restoration of peripheral function. One key class of deficits is due to changes in central inhibitory synapses, which play a fundamental role in all aspects of auditory processing. This review focuses on the anatomical and physiological alterations of inhibitory connections at several regions within the centra...

This retrospective study was undertaken to identify the prevalence of hearing loss in the homeless population and its implications for vocational rehabilitation. Audiometric threshold data for adult residents of an urban homeless shelter were collected and reported. Subjects with hearing loss were identified and defined by their binaural high-frequency pure tone average (B-HFPTA). Those subject...

The purpose of this study was to examine the relationship between hearing loss and working memory using an automated visual, verbal working memory task in adults with hearing loss. An exploratory, prospective, group design was used to evaluate the performance of 29 adults with varying hearing loss severity. Findings reported here are from a subset of data taken from a larger training study. Par...

Hearing loss has become very common today. Approximately 10% of the population suffering hearing impairment due to different reasons across the world. Among all most commonly observed sensorineural hearing loss caused due to poor cochlear hair cells function and damages to cochlear nerve. Sensorineural hearing loss is characterized by widening of auditory filter which leads to spectral masking ...

This study assessed the effects of binaural spectral resolution mismatch on the intelligibility of Mandarin speech in noise using bilateral cochlear implant simulations. Noise-vocoded Mandarin speech, corrupted by speech-shaped noise at 0 and 5 dB signal-to-noise ratios, were presented unilaterally or bilaterally to normal-hearing listeners with mismatched spectral resolution between ears. Sign...

We present four case reports of elderly hearing-impaired persons demonstrating a binaural interference effect. Performance measures were poorer when stimulation was binaural than when it was monaural. In the first case the effect is shown for aided speech recognition scores. In the second case it is shown in topographic brain maps of the middle-latency auditory evoked potential. In the third an...

This paper investigates to what extent users of bilateral and bimodal fittings should expect to benefit from all three different binaural advantages found to be present in normal-hearing listeners. Head-shadow and binaural squelch are advantages occurring under spatially separated speech and noise, while summation emerges when speech and noise coincide in space. For 14 bilateral or bimodal list...
