Unfortunately, hearing screening for this population is unable to rely on standard, behavioural test batteries. To facilitate future improvements in screening protocols, this study investigated the results of tympanometry and transient evoked otoacoustic emission (TEOAE) testing for a group of children with Down syndrome. Assessments were not conducted in the artificial context of a clinic or laboratory, but within the school environment. Outcomes are reported for 27 subjects with a mean age of 10 years 5 months (SD = 4;11). Tympanometry testing was failed in at least one ear by 41.7% of subjects, while a failure rate of 81.5% of subjects was observed for TEOAE testing. Therefore, it is concluded that immediate review of hearing screening programs for students with Down syndrome is highly advisable.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124708756","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}

Six adults were evaluated under three listening conditions: cochlear implant and hearing aid (CIHA), cochlear implant with unilateral microphone (CI-UM) and cochlear implant with bilateral microphones (CI-BM). Performance measures included dichotic speech perception in noise, horizontal localisation and functional performance in real life. The results of speech testing showed a significant advantage of CIHA and CI-BM over CI-UM. The localisation task showed that CIHA was significantly better than CI-BM or CI-UM. The functional performance questionnaires showed that CIHA was better than CIUM, and similar to or better than CI-BM in real-life situations. The subjects also commented on the improved quality of sound provided by the use of a hearing aid with a cochlear implant. We conclude that both CIHA and bilateral microphones with a single implant can provide real advantages for dichotic speech perception in noise over an implant system with a single microphone input when speech originated from the non-implanted side. CIHA provided extra benefits in localisation and functional performance in real life, and is the option of choice for users of unilateral cochlear implants who have some residual hearing in the non-implanted ear.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131002502","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}

Therefore, for this population, a poor score on central tests may not be an indication of an auditory processing problem, but rather the consequence of linguistic experience. In view of the potential dangers of misdiagnosis inherent in administering central auditory tests to children with ESL highlighted by these studies, a small preliminary exploration was conducted to examine the effect of ESL on the recently developed Macquarie Pediatric Speech Intelligibility Test (MPSI; Cameron, Barker, and Newall, 2003). A trend emerged whereby having English as a second language affected performance on the dichotic condition of the test at the least favourable message to competition ratio (MCR), with ESL children performing at levels usually associated with auditory processing disorder (APD). This trend highlights the need for a larger study to determine the differences in performance on the MPSI between ESL listeners and normative data collected from native English-speaking controls. Possible reasons for the results of the preliminary exploration are discussed in relation to previous research.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134197371","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}

There has been some suggestion that due to differences in methodology different loudness tests result in different prediction of the non-linear amplification when applied according to the same fitting rationale. However, this has not been empirically verified. In this paper the inverse compression ratios prescribed based on a pure loudness normalisation technique and loudness data measured with two different categorical loudness scaling tests were compared for 20 test ears. The data showed that the two loudness tests produced significantly different prescriptions for non-linear amplification and that the discrepancy in prescription was non-linearly related to hearing threshold level with the greatest discrepancy found for cases with moderate loss. Differences in methodology used to obtain the loudness data are argued to be the most likely reason for the measured discrepancy in prescription. Up to 50% of a large variability in data across hearing threshold levels was explained by individual participant factors, suggesting that the interpretation of the two loudness tests varied across participants. The results imply that any fitting rationale based on frequency-specific loudness data is only valid for the test conditions in which the loudness data are obtained, and a hearing aid fitting based on frequency-specific loudness data should be verified.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133371203","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}

The PSI is a speech test which utilises competing sentences presented dichotically and monotically at various message to competition ratios (MCRs). The purpose of the present study was to develop an Australian version of this test for use in local clinics. The Macquarie Pediatric Speech Intelligibility Test (MPSI) was recorded using Australian speakers, in order to control for linguistic differences which could affect performance on the test by Australian children. Normative data was collected from 51 normally hearing Australian children aged 7.0 to 8.11 years. The scores below which a child's performance on the MPSI is considered indicative of APD were found to be comparable to those calculated for the original North American version of the test. No significant differences in performance between 7- and 8-year-olds were detected for either the monotic or dichotic conditions of the MPSI. The degree of right or left ear advantage on the dichotic task was very slight, regardless of handedness, making differentiating between the right and left ears when tabulating cut-off scores unnecessary. The preliminary results indicated that the MPSI will be a valuable tool in the identification of APD in the Australian school-aged population.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114288686","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}
