While this ear disease is often preventable, it continues at prevalence rates estimated as high as 80%. In many cases, the use of a hearing aid is the best-practice intervention and often allows the wearer to hear family, friends and teachers. Yet, the use of hearing aids among Indigenous Australians is extremely low. This is the first study to investigate the 'Hearing Aid Effect' (HAE), which is the stigma associated with wearing a hearing aid, in an Indigenous Australian population. Participants in this study included 5 to 12-year-old Indigenous Australian children. Children viewed pictures of Indigenous children, of similar age, with and without visible hearing aids, and then rated their perceptions on an attitude scale. Participants were also involved in a learning-based intervention on the importance of wearing hearing aids. The results indicated a strong HAE. Indigenous Australian children had a more negative attitude towards peers who wore hearing aids in comparison to peers who did not wear hearing aids. Additionally, females tended to rate males more negatively than females on most questions. Males rated females more negatively on questions regarding friendship, sport and whether they can attend the same school. The intervention had a significant effect on the children's attitude toward hearing aids. The study results indicate that children of this early age have constructed characteristic stigmatisations concerning their peer's use of hearing aids.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"155 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123531902","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 data were drawn from the Australian Hearing national database on all aided children under 21 years of age as at December 2006. The results indicated that children who were screened and diagnosed soon after birth were fitted by a median age of 3.4 months in New South Wales. The prevalence of moderate and more severe hearing loss (threefrequency average in the better ear of ≥ 40 dB HL) rises from 1.04/1000 live births at 3 years of age to 1.57/1000 live births for children between 9 and 16 years of age. The prevalence of mild degrees of hearing loss (threefrequency average in the better ear < 40 dB HL) rises from 0.28/1000 live births at 3 years of age to 1.68/1000 live births at 9 years of age and older. The findings show that early detection leads to early amplification. The change in prevalence with age implies that newborn hearing screening needs to be supplemented by hearing screening at later ages of early childhood so that timely amplification can be provided.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128795071","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 MLD is a psychoacoustic measure of binaural interaction and central auditory processing related to extracting signals from noise backgrounds. The MLD is a more efficient and less culturally biased predictive measure in the assessment of binaural interaction and auditory processing disorders compared to many linguistic or electrophysiologic techniques. In the first MLD condition, the masking noise was an interaurally in-phase (No) 160 Hz wide noise band centred on 500 Hz. The 500 Hz pure tone signal was generated digitally (rise-fall time, 100 msec, duration 2 sec), and presented either interaurally in-phase (So) or 180 degrees out-of-phase (S). In the second MLD condition, the 500 Hz pure tone signal was interaurally inphase (So) and the noise was either interaurally in-phase (No) or 180 degrees out-of-phase (N). The data were obtained using a simplified up-down adaptive procedure. Signals were presented using a GSI 16 audiometer with input from a digital audio system. The mean MLD was 11.21 dB (SD = 1.67) when the signal phase was changed and was 7.83 dB (SD = 1.75) when the noise phase was changed. Comparison is made between other studies that have measured the MLD. However, this would be the first such normative data obtained from Australian children and allows a comparative basis to other children, especially those with suspected binaural dysfunction.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"13 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":"127746844","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 use of FM hearing aids in the classroom coupled to a bone conduction (BC) transducer has beneficial application even when considering improved binaural function. This study investigated speech discrimination in diotic and dichotic noise. Confusion matrices were obtained for consonant-vowel (CV) exemplars presented to normal hearing subjects through BC in both correlated and uncorrelated noise. Thirty-six university-aged listeners served as subjects. The CV exemplars were presented randomly, 20 times each, for a total presentation of 420 stimuli for each subject. The stimuli were presented to the subject at a signal level of 55 dB HL through a B-70A BC transducer worn at the forehead position. Each subject was requested to write down the consonants as they heard them. Three conditions were utilised. In condition 1, CV exemplars were presented through air conduction (earphones) in order to assess the quality of the testing apparatus, including the CV exemplars, and to provide a reference for comparison to BC. In condition 2, these exemplars were presented through the BC transducer. Condition 3 involved two separate listening tasks in which CV exemplars were presented through the BC transducer and band-limited white noise was presented binaurally, correlated and uncorrelated, through earphones. The results indicated that speech discrimination with BC was excellent and equal to air-conduction consonant identification. The confusion matrices showed higher speech discrimination scores in the uncorrelated noise condition, revealing a binaural advantage for BC hearing. Distinctive feature identification was also greater for the uncorrelated noise condition.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"15 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":"114185288","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}

It represents the improvement in threshold sensitivity under antiphasic listening conditions relative to homophasic conditions. A low frequency pure tone (500 Hz) was presented in-phase (So) binaurally to the subject in the presence of a phasic masker (No). The behavioural threshold obtained at this condition was used as a reference. The behavioural threshold was again determined with the pure tone stimulus presented antiphasically (S), and the difference in thresholds was calculated to determine the MLD. The MLD was measured for a 500 Hz pure tone in 36 Aboriginal children (16 males and 20 females) from an Aboriginal community school (Nguiu, Tiwi Islands) where conductive hearing loss, due to otitis media, is endemic. The control group consisted of 62 normal-hearing children (40 males and 22 females) from a private school in Darwin. Aboriginal children showed a mean MLD of 7.76 dB whereas the control group exhibited a mean MLD of 11.21 dB. Aboriginal children showed a consistently lower MLD than non-Aboriginal normal-hearing children. Auditory processing disorders (APDs) have been shown to be related to early auditory deprivation, a common feature of chronic conductive hearing loss observed frequently in Aboriginal children. Thus, the MLD provides a metric for assessing binaural hearing abilities which may be relevant to the assessment of APD and hearing aid fitting. The MLD is a less linguistically, less culturally biased predictive measure and may be more easily administered than many speech and language test procedures used in diagnosing APD.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"368 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":"114828695","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 aim was to investigate whether a diversity of stimuli at each test frequency assists in maintaining the interest of the child for a longer duration than a constantly repeated stimulus when using Behavioural Observation Audiometry (BOA) and Visual Reinforcement Audiometry (VRA). A set of 10 stimuli was selected, 5 centred at 1000 Hz and 5 centred at 4000 Hz. They were: 1000 Hz warble tone, speech /ala/, noisemaker (synthetic melody), environmental (dog barking, music box), 4000 Hz warble tone, speech/isi/, noisemakers (nonreed squeaker, manchester rattle), and an environmental sound (telephone ringing). Forty babies and toddlers between the ages of 4 months and 20 months participated in the study. The findings indicated there was no significant effect of variable stimuli for the younger children assessed using BOA. For older children assessed using VRA, there was a significant beneficial effect of the variable stimuli at 1000 Hz, but not for those at 4000 Hz.","PeriodicalId":114768,"journal":{"name":"Australian and New Zealand Journal of Audiology","volume":"28 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":"129953225","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}
