Audiologic test results were reviewed for 30 patients whose hearing was preserved following eighth nerve tumor surgery. Improved auditory brainstem response tracings were seen as probably indicating increased neural synchrony due to reduced pressure on the cochlear nerve following surgery, whereas reduced hearing sensitivity probably reflects…

This paper examines the case for modality specificity as a criterion for improving the specificity of diagnosing central auditory processing disorders. Demonstrating the modality-specific nature of sensory processing deficits is seen as one way to rule out nonperceptual factors as explanations for observed dysfunction. (Author)

This article discusses the accuracy of bone-conduction auditory brainstem response (BC-ABR) tests to determine the presence and severity of conductive hearing impairment. It provides warnings about technical pitfalls and recommends incorporating BC-ABR protocols for routine clinical use. It concludes that the method allows estimating cochlear…

This article introduces the use of multilayered artificial neural networks in hearing aid noise recognition. It reviews basic principles of neural networks, and offers an example of an application in which a neural network is used to identify the presence or absence of noise in speech. The ability of neural networks to "learn" the…

This report examines how the teacher-practitioner model has been developed and is implemented at Rush-Presbyterian-St. Luke's Medical Center (Chicago, Illinois) in the professional training of audiologists. Discussed are the model's attributes, integration of the clinical and academic programs, advantages of the model, demands of the model, and…

Measures of transient evoked otoacoustic emission (TEOAE) reproducibility were obtained for 506 ears of 260 children and young adults. Findings suggest that TEOAEs provide useful information in routine clinical practice and may be employed to screen for the presence of hearing loss in children and young adults. (DB)

Two audiologists discuss the measurement of hearing aid benefits by means of the Abbreviated Profile of Hearing Aid Benefit (APHAB). They also report on numbers of listening problems identified using the APHAB subscales, and identify areas where further benefits are more and less likely. (DB)

Eight subjects participated in a comparison of the multipeak (MPEAK) and spectral peak (SPEAK) speech coding strategies of the Nucleus 22-channel cochlear implant system. Overall, speech recognition performance was significantly higher with the SPEAK strategy than with the MPEAK strategy on all speech tests. (Author)

Seven subjects participated in a comparison of the normal and noise suppression settings on the Spectra 22 speech processor of the Nucleus 22-channel cochlear implant system. Group data revealed no significant difference in performance between the two settings for either monosyllabic words in quiet or sentences presented in background babble.…

Interviews with 37 individuals in Nicaragua were the basis of this review of the audiology field in that nation. The review covers the prevalence and etiology of hearing impairment, training for audiologists, government services for individuals with hearing impairment, private agencies concerned with hearing impairment, and fitting and use of…
