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 and fourth cases it is shown for both aided speech recognition and the middle-latency response. The… 

Behavioral and electrophysiologic binaural processing in persons with symmetric hearing loss.

The behavioral and electrophysiological measures used in the present study clearly showed evidence of reduced binaural processing in subjects with symmetrical pure-tone sensitivity, which underscores the importance of understanding bINAural auditory processing and how these measures may or may not identify functional auditory problems.

A case study of a child (KB) who demonstrated binaural interference is reported, at which time word-recognition scores under phones were markedly asymmetric, reflecting significantly better performance for the aided ear than the unaided ear, despite similar un aided pure-tone sensitivity.

Unsuccessful use of binaural amplification by an elderly person.

Results suggest that age-related changes in interhemispheric transfer of auditory input via corpus callosum may underlie the preference for monaural amplification.

Monaural and Binaural Speech Reception Thresholds in Normal Children and Those at Risk for Central Auditory Processing Disorders

Children with central auditory processing disorders (CAPD) have a normal pure-tone audiogram, however, they have difficulty understanding speech in the presence of background noise. The present study

Individual Differences in Behavioral and Electrophysiological Measures of Binaural Processing Across the Adult Life Span.

The lack of significant correlations among variables suggests that each is an important measurement of binaural abilities, including age, which suggests that these listeners may benefit from alternative forms of audiologic rehabilitation.

Dichotic Listening, Event‐Related Potentials, and Interhemispheric Transfer in the Elderly

There may be a significant loss of efficiency of interhemispheric transfer of auditory information through the corpus callosum with age, and such age-related deficit might have important implications for the effective use of binaural information by elderly persons.

Slope analysis of Auditory Brainstem Responses in children at risk of central auditory processing disorders.

The results suggest that there may be several subcategories among children who are found to be at risk for central auditory processing disorders (CAPD) with language impairment, which may comprise children who exhibit poor ABR morphology, especially during bINAural stimulation conditions, which could be due to binaural interference.

Complementing behavioral measures with electrophysiological measures in diagnostic evaluation: a case study in two languages.

The pattern of results is consistent with previous findings in demonstrating that the left-ear deficit in this patient derived from an auditory-specific defect rather than from any of the extra-auditory factors associated with language facility or cognitive decline.

Investigation of binaural interference in normal-hearing and hearing-impaired adults.

Of 48 subjects tested, only 2 exhibited significant evidence of binaural interference, a result that is close to that expected by chance.

Listeners who prefer monaural to binaural hearing aids.

The results indicate that listeners with an auditory-based deficit in dichotic listening may function better with a monaural hearing aid fitting or with an assistive listening device such as an FM system.

Binaural voltage summation of brainstem auditory evoked potentials: An adjunct to the diagnostic criteria for multiple sclerosis

This study evaluated the extent of binaural summation of BAEPs in patients with MS and found no evidence that brainstem potential amplitude is reduced and none to suggest that bINAural stimulation results in increased amplitude.

Binaural interaction in early, middle and late auditory evoked responses.

While absent in waves I and III of the brainstem response, binaural interaction or fusion appears in wave V and in the middle latency response, and seems to be greatest in the cortical response N1P2N2.

Binaural interaction measured behaviorally and electrophysiologically in young and old adults.

The young subjects showed the expected reduction of binaural wave Pa amplitude compared to monaural sum responses, while the older subjects, as a group, did not; no significant correlations were found between behavioral and electrophysiological tests.

Magnitude of diotic summation in speech-in-noise tasks: performance region and appropriate baseline.

Binaural interaction in human auditory brainstem evoked potentials.

Binaural interaction in these potentials reflects binaural processing of low-frequency acoustic stimulation, and amplitude and latency depended on click polarity.

Forms of binaural summation and the implications of individual variability for binaural hearing aids.

Experimental results with normally-hearing listeners and with aid users show that binaural summation is likely to lead to gain settings of about 6 dB lower than with otherwise equivalent monaural amplification, which may be relevant to prognosis for bINAural aiding.
