Other forms of auditory deficit, such as auditory processing disorder, have rarely been considered in the assessment of patients with moyamoya disease. A case of central auditory processing disorder is presented in a 26-year-old female of Chinese ethnicity with moyamoya disease. The patient had bilateral, near-normal hearing thresholds and normal immittance audiometry results. However, she displayed poor speech perception in noise and her results for other auditory processing tasks were markedly abnormal. These findings suggest that patients with moyamoya disease may benefit from a full auditory assessment that includes tests of auditory processing skills.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128208173","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}

If compensating communication strategies and support programs are to be engaged, a child's hearing loss needs to be identified. Teacher recommendations are an important source of referrals for hearing tests, with school screening programs now being infrequent or nonexistent. However, cultural differences in Aboriginal children's attentional styles, together with some children with hearing loss using more face-watching as a compensatory strategy, can confuse non-Aboriginal teachers as to who may need referral for hearing testing. This article describes a classroom case study that found culturally different attentional styles and compensatory face-watching, similar to that described in a remote school, among some urban Aboriginal children. The attentiveness of one child with hearing loss confused teachers. The implication for the identification of Aboriginal children's hearing loss is discussed.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132653414","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}

No significant change in the amplitude of TEOAE was observed across the infant test period, within and between subjects. Overall TEOAE amplitude of the infants was found to be approximately 10 dB higher than a group of adults tested using identical procedures. The stability of the response amplitudes during the neonatal period support the introduction of an infant specific signal-to-noise ratio pass criteria to improve the sensitivity of TEOAE to milder losses. The findings also support the use of in situ stimulus correction to minimise the impact of maturational effects on response amplitude.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117314296","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}

Kenworthy","doi":"10.1375/AUDI.27.2.113","DOIUrl":"https://doi.org/10.1375/AUDI.27.2.113","url":null,"abstract":"This study investigated the magnitude, reliability, and frequency of occurrence of peaks in the fine structure of the distortion product otoacoustic emission audiogram (DPOAE-gram). Thirty-six normal-hearing women were tested. Fine structure was assessed using 1/15 octave intervals (1000-8000 Hz) with primary tones presented at L1 = 65 and L2 = 55 dB SPL. DPOAE amplitudes were obtained at five frequencies (f2 = 1500 Hz, 2000 Hz, 3031 Hz, 4000 Hz, and 6031 Hz) for three values: one-frequency, three-frequency, and five-frequency averages. Compared to the one-frequency condition, averaging DPOAE amplitudes across three frequencies resulted in an improvement in reliability of approximately 1.0 dB. Because of the improved reliability, the three-frequency condition may be preferred when monitoring the effects of noise or ototoxic drugs. The number and reliability of amplitude peaks was ascertained. The reliability of the peak amplitudes (maxima or minima) was assessed with the standard deviation of test-retest differences. This value was 2.9 dB, suggesting that approximately 95% of measurements revealed test-retest differences within (+ or -) 5.9 dB. Thus, when obtaining measurements in 1/15 octave steps, it is common to observe maxima/minima in the DPOAE-gram of <6 dB that reflect test-retest variability. Moreover, due to chance, peaks greater than 6 dB will be observed in approximately 5% of measurements. Individual data points in the DPOAEgram may fall below normative values because of hearing loss, unreliability, or because of fine structure minima. Therefore, clinicians should conduct repeat testing and/or fine resolution measurements to ascertain whether the abnormal test results are due to cochlear impairment or normal variability.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131768714","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}

All performed more than 5 standard deviations below the mean normative data score for their age group on both the Random Gap Detection Test, and the spatial advantage measure of the newly developed Listening in Spatialized Noise test (LISN ). The LISN spatial advantage measure assesses the listener's ability to use binaural cues to comprehend a target story in the presence of spatially separated distracter sentences, without being affected by differences between participants in variables such as linguistic skills. The children were also greater than 2 standard deviations below the mean on the LISN high-cue SNR, which assess the actual signal-to-noise ratio required to understand the story when all cues are present. Similarities and differences in presenting profiles, and teacher reports, are discussed, and results on a range of other central assessment tools are also detailed. The results suggest that these children would benefit from an improved signal-to-noise ratio in the classroom. Other management strategies are also outlined.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124029309","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}

This clinical procedure uses 1000 Hz and 4000 Hz warble tones at screening levels of 30 dB SPL and 25 dB SPL respectively. A range of nontonal stimuli were recorded on compact disk, their dominant frequency identified, and the stimuli octave-band filtered. Following a survey among experienced paediatric audiologists, a set of six stimuli was selected. These were 1000 Hz and 4000 Hz warble tones, filtered speech at 1000 Hz (/ala/) and 4000 Hz (/s/), and filtered noisemakers at 1000 Hz (a synthetic simple melody) and 4000 Hz (a non-reed squeaker). Fortytwo babies and toddlers between the ages of 6 months and 30 months participated in the project. The results showed that some nontonal stimuli were equally effective to traditional warble tones, one was less effective, and none were more effective.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123855349","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}

Behavioural hearing thresholds cannot be predicted from electrophysiological assessment and may vary from normal limits to profound hearing loss. The impact of the auditory neuropathy on a child's ability to use their residual hearing cannot be predicted from the behavioural hearing thresholds and is variable among individuals. Infants do not demonstrate behavioural responses at threshold in the first few months of life, nor is it possible to determine speech perception ability at this age. These factors combine to present difficulties in counseling families about the degree of hearing loss and potential implications for their child, and in prescribing and evaluating amplification, if fitted.

A review of 14 papers was conducted to determine the validity of this belief and the data from three of the studies (Cox & Alexander, 1992; Horwitz & Turner, 1997; Humes et al., 2002) were then examined in closer detail. The audiometric data for 175 subjects, for whom use gain was measured at various intervals postfitting, was divided into 'new' (N = 98) and 'experienced' (N = 77) groups. For each of these subjects, the NAL-R target was calculated and the prescribed gain was compared to the use gain. An analysis of these data, along with the conclusions of the other papers reviewed here, suggests that there is no significant difference between the gain preferences of new and experienced hearing aid users, nor do the gain preferences of new users change over the first 12 months of hearing aid use.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132593956","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}
