Spouses of older people with hearing impairment frequently urge their hearing impaired partners to see help for their hearing difficulties. Only a minority of individuals with hearing impairment are self motivated, with the majority of clients, especially older clients, presenting at audiology clinics under the persuasion or influence of their spouse or significant other. This highlights the important role that spouse play in initiating aural rehabilitation and indicates that spouses of older people with hearing impairment ma become so frustrated with their partners hearing loss that they are often the primary reason why the hearing impaired person presents for audiological services. To date, however, the number of studies addressing the effect of hearing loss on significant others is limited Those studies that have investigated the effect of hearing impairment on families are commonly focused on the person with the impairment and mos commonly, the significant other has merely been use as a proxy to describe the perceived problems of his or her spouse. Further, there has been no systematic in depth investigation of the needs of spouses of older people with hearing impairment, including the effect of retirement and the increase in time spent together with the majority of studies focusing primarily or younger spouses of workers affected by noise-induce hearing loss. The cumulative effect of experiencing many years of hearing difficulties with a partner ma also influence the extent to which older spouses are affected by hearing impairment. The primary purpose of this article is therefore to critically review the existing literature on the effects of hearing impairment of spouses. It will also provide a rationale for the importance of this topic as a clinical issue and suggest some future directions for research in this area.

The aims of the study reported in this article were to (i) investigate the levels of hearing impairment, activity limitations and participation restrictions in the residents of an aged care facility; (ii) assess the communication environment of the facility; and (iii) describe the implementation and outcomes of a holistic, communication- focused approach to the audiological rehabilitation of residents. Fifteen residents (aged 79 to 99 years) were recruited to this study. Quantitative and qualitative data were collected using pure-tone audiometry as a measure of impairment, self-report measures of activity limitations and participation restrictions, and a modified version of the Communication Environment Assessment and Planning Guide to examine environmental factors. Interventions were administered both at the level of the individual as well as the wider communication environment. Results indicated that 14 of the 15 residents were hearing impaired, with four experiencing significant levels of activity limitations and participation restrictions. A moderate correlation was obtained between impairment and activity limitations/participation restrictions. Eight participants were assessed post-intervention; although activity limitations/participation restrictions scores did not show any significant differences, qualitative data indicated some of the benefits of the program. The study not only supported previous findings on the nature of hearing impairment, activity limitations and participation restrictions in residents of aged care facilities, but also importantly highlighted the difficulties faced by clinicians and researchers working in this environment.

This report provides a quantitative summary of the initial findings in a series of investigations into the validity and reliability of repair behaviour recorded in free conversation in clinical settings between adults who have acquired hearing impairments (HIs) and their frequent communication partners (FCPs). Seven adults who have severe or greater acquired HIs (and who had subsequently been either fitted with hearing aids or undergone cochlear implantation) were audio-recorded undertaking a 20-minute free conversation in a quiet clinical setting with their chosen FCP. Transcriptions of the conversations were analysed for the occurrence of repair sequences following the Conversation Analysis (CA) model. A total of 735 completed repair sequences were identified across the seven conversations, the majority occurring within the same turn as the trouble source. No difference was noted in the frequency with which all but one trajectory was initiated by either the HI or FCP participants. Repairs initiated by the HI participant and repaired by the FCP in response to a trouble source in a previous turn by the FCP occurred significantly more often than the same sequence initiated by the FCPs. The results emphasise the usefulness of framing repair activity arising from acquired HI in the broader conversational act of repairing and the CA model.

This study aimed to develop and evaluate a questionnaire for mass screening of rural school children in China. A total of 154 children, ages ranging from 6-13 years (mean = 9.3 years, SD = 1.7), were screened using the Chinese Hearing Questionnaire for School Children (CHQS-II). The CHQS-II was designed to detect cases at risk of otitis media with effusion and/or at least a moderate hearing loss in one or both ears. The test performance of the questionnaire was determined through comparison with 'gold standard' assessments. The diagnostic protocol was failed by 9.7% of participants, whilst the questionnaire was failed by 47.4%. Overall, the CHQS-II was found to be only moderately accurate (.62) as a screening system. When compared with standard diagnostic tests, its sensitivity was moderate but its efficiency was poor. Therefore, it cannot be recommended as a technique for mass hearing screening of rural school children in China.

This study examines pre-fitting expectations of hearing aid performance, problems, cost and upkeep, and dispenser service by 36 Chinese speaking first-time hearing aid users (mean age = 66 years). The mean average hearing threshold of the group was 54 dB HL. Prior to aid fitting, participants expected good aided performance, few problems, low cost and good service. Expectations about performance in different situations were significantly related to each other, as were various service quality descriptions. Expectations about specific problems and cost did not correlate. The relationship between pre-fitting expectations and satisfaction measured at 3 months post-fitting was subsequently investigated. Greatest post-fitting satisfaction was noted for service quality items and listening in easy situations and lowest satisfaction was evident for difficult listening situations. re-fitting expectations did not correlate with general satisfaction with hearing aids or dispenser service. Higher expected ability to hear in noise and television/radio was associated with higher satisfaction post-fitting in same situations. Expectations of fewer problems in appearance pre-fitting were related to satisfaction with he dispenser post-fitting. Higher expectation of the dispensers communication ability was related to satisfaction with communication with the dispenser in the long-term. Overall, the results of this study indicated hat pre-fitting expectations do not have a strong association with post-fitting satisfaction.
本研究调查了36名中文助听器初次使用者(平均年龄66岁)对助听器安装前的性能、问题、成本和维护以及分配器服务的期望。各组平均听阈为54 dB HL。在辅助装配前，参与者期望辅助性能好、问题少、成本低、服务好。在不同情况下对性能的期望彼此显著相关，各种服务质量描述也是如此。对具体问题的预期与成本并不相关。随后调查了预拟合期望与3个月后测量的满意度之间的关系。在容易的情况下，服务质量项目和听力的满意度最高，而在困难的情况下，满意度最低。重新装配期望与对助听器或分配器服务的总体满意度无关。在噪音和电视/广播环境中，较高的听力预期能力与同样情况下较高的拟合满意度相关。对外观预拟合问题较少的预期与对分配器后拟合的满意度有关。对配药员沟通能力的期望较高，与长期与配药员沟通的满意度有关。总体而言，本研究的结果表明，预拟合期望与后拟合满意度没有很强的关联。

To avoid the adaptation effects caused by increasing the stimulus repetition rate in frequency-specific ABR testing, some researchers have trialed alternative stimuli called 'chained stimuli'. The current study analysed the latency variance in Wave V for auditory brainstem responses evoked by representative chained stimuli (tone-pulse series stimulation with simultaneous Gliding HIghpass NOise Masker -'GHINOMA') and conventional nonchained stimuli (tone bursts) and found that these 'chained stimuli' can be used to obtain frequency-specific ABR waveforms in less time compared to conventional stimuli, without sacrificing the 'quality' of waveforms obtained. Our findings suggest that the test-retest repeatability of chained stimuli is no different than that for conventional nonchained stimuli, and that chained stimuli can be effectively substituted for conventional stimuli with no degradation in the quality of responses. The observed improvements in morphology, and the reduction in overall testing time, make the use of chained stimuli appealing in clinical practice.

This study presents tympanometric normative data for Australian children at school entry in view of the lack of age-specific population-based data for this group. Participants were 327 children (164 boys, 163 girls) aged between 5 and 6 years, who had no history of middle ear infection, and passed pure-tone screening at 20 dB HL. Normative values for static admittance (SA), ear canal volume (ECV), tympanometric peak pressure, tympanometric width (TW) and tympanometric gradient were established. Based on these normative data, the use of the ASHA (1997) guidelines for medical referral, in which ECV > 1.0 ml in the presence of a flat tympanogram, SA 200 daPa may not provide the best criteria for Australian children aged between 5 and 6 years. If SA < 0.3 ml were used instead of SA < 0.16 ml, a greater proportion of Australian children would have failed tympanometry, thus increasing the false alarm rate.

Vestibular Evoked Myogenic Potential (VEMP) assessment may assist in the diagnosis of balance disorders. Currently, however, there are limited guidelines available for clinicians to maximise its application. This study aimed to develop procedures for ensuring reliable VEMP recordings in the clinical setting and to provide comprehensive normative data. VEMP responses from 30 normal adults were collected using the Biologic Navigator. The factors of stimulus type, frequency and intensity were considered. Only stimulus type had a significant effect on VEMP recordings, with responses from click stimuli having lower thresholds, shorter latencies and higher test-retest correlations than the tone burst stimuli. However, as the maximum click intensity of the system was 90 dB nHL, the click stimulus only elicited responses from 73.3% of ears. The results of this investigation, along with a review of the existing literature, have led to the creation of a clinical protocol for VEMP testing.

The aim of this study was to investigate current audiological outcomes of Cherbourg schoolchildren and compare these outcomes to those obtained in a 1972 study of hearing health in the same community. Seventy-eight primary school children of Cherbourg State School participated in the study. Their peripheral hearing and middle ear function were tested using pure-tone air conduction audiometry and tympanometry respectively. A significant improvement in the hearing status of this population was noted compared to that reported in 1972. The improvements in the hearing status of Indigenous schoolchildren at Cherbourg can be attributed to a number of factors, including increased awareness of both ear health and general health, as well as the introduction of hearing health care services, over the past three decades.

This study aimed to investigate the benefit gained by older people in auditory-visual speech perception compared to auditory-only perception and to investigate the correlation between visual acuity and benefit gained. A total of 77 community-based older people participated in the study. Pure-tone audiometry showed that 36% had normal hearing, 40% had a mild hearing loss and the remainder (23%) had a moderate or greater loss. Objective measurements of corrected distance and near visual acuities were obtained using the Bailey-Lovie logMAR distance and near visual acuity tests. According to the criteria used in the present study, 34% had some distance vision impairment and 9% had some near vision impairment. The benefit gained in auditory-visual speech perception was determined by comparing auditory-only and auditory-visual performance on the Bamford-Kowal-Bench Australian Version Speech reading Test. An average visual benefit of 28.8% was achieved by the participants, and, for the vast majority of participants (86%), the benefit gained was statistically significant. A significant correlation was not found between either distance or near visual acuity and benefit gained in auditory-visual speech perception. The implications of these findings are that it is important for audiologists to recommend the use of lipreading to older clients, irrespective of their visual impairment, as the majority will gain significant benefit from the use of visual cues.
