Results revealed notably high intrasubject test-retest reliability within the two groups of listeners for the male speech condition and in normal listeners for the female speech condition. Preferences assigned for any one of the three stimuli were found to be statistically correlated with those assigned for each of the other two stimuli. Furthermore, preferences of the otopathologic listeners were statistically equivalent those yielded by the normal listeners. Within the separate groups of listeners, rankings derived from the preferences of individual subjects were highly related to those of the other subjects within the respective group, suggesting the lack of a hearing aid-listener interaction. The relationship between preferences and \"goodness\" of selected electroacoustic characteristics, examined descriptively, was found to be equivocal. Overall results suggest that, while paired-comparison quality judgments may serve as an adequately reliable and adequately differentiating index of behavioral performance with hearing aids, incorporation of such a task within the traditional philosophy of hearing aid evaluation appears unjustifiable.</p>","PeriodicalId":76026,"journal":{"name":"Journal of the American Audiology Society","volume":"3 4","pages":"179-88"},"PeriodicalIF":0.0,"publicationDate":"1978-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11861507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Editorial. Definition of audiology.","authors":"J D Harris","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>It is noted that the generic term audiology as the science of hearing, and the concept of the multidisciplinary audiology center, is some years older than the emergent independent profession of clinical audiology. The broader term is still useful as a device to lend much needed cohesion to a variety of approaches to the study of hearing, as a term to elicit public support for hearing research in general, and as a device to attract young persons to aspects, not necessarily clinical, of the biology of the auditory process. A trend is deplored to dissuade or even force all persons involved in serious study of hearing to refrain from designating themselves as audiologists; it is hoped that the words audiology and audiologist will continue to be very broadly defined, and it is thought that to restrict them would do ASHA-certified audiologists in the long run more harm than good. It is suggested that these virtues of the generic word audiology could be amicably retained, while offering a fully professional identity to practitioners of audiology in the clinic, by rewording the current \"CCC-A\" to read \"Certificate of Competence in Clinical Audiology\" and its holders be known, as in fact they commonly are, as \"Clinical Audiologists;\" this by analogy with the current widespread practice in psychology.</p>","PeriodicalId":76026,"journal":{"name":"Journal of the American Audiology Society","volume":"3 3","pages":"121-5"},"PeriodicalIF":0.0,"publicationDate":"1977-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11818852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acoustic reflex responses were monitored during the presentation of fatiguing stimuli consisting of interrupted and continuously presented octave noise bands (500--1000 and 1500--3000 Hz) presented at 98 dB sound pressure level.

Greater impedance changes were elicited by the high band noise than by the low band noise exposure.

It was shown that parallel and side branch vents produce similar low frequency filtering effects and vent-associated reactance resonances.

This effect is not seen when the input system is associated with a parallel vent. Data obtained in the real ear canals were compared to analogous measurements made using an acoustical model (the Zwislocki coupler) and an electrical model designed to simulate the hearing aid receiver, input tubing, earmold, ear canal, and eardrum. Both models yielded data very similar to the real ear results.
