This study measured the prevalence of hearing impairment, and major demographic factors that influence the prevalence, in a representative South Australian adult population sample aged > or = 15 years.

The study group was recruited from representative population surveys of South Australians. Participants in these surveys who reported a hearing disability were then recruited to an audiological study which measured air and bone conduction thresholds. In addition a sample of those people who reported no hearing disability were recruited to the audiological study.

The data reported in this study are the first in Australia to assess the prevalence of hearing impairment from a representative population survey using audiological methods. The data show that 16.6% of the South Australian population have a hearing impairment in the better ear at > or = 25 dBHTL and 22.2% in the worse ear at the same level. The results obtained in this representative sample compare well with those obtained in the British Study of Hearing, although some differences were observed.

Overall, there are only a few studies worldwide that have audiologically assessed the impairment of hearing from a representative population sample. The overall prevalence of hearing impairment in Australia is similar to that found in Great Britain, although there are some differences between the estimates of severity of impairment and some sex differences. The corroboration of the two studies reinforces the status of hearing impairment as the most common disability of adulthood. The present study also showed that there are a large number of Australians who may benefit from a more systematic community-based rehabilitation programme including the fitting of hearing aids. Secondly, the study identified the need for health goals and targets for hearing to be based on an epidemiological approach to the problem.

    • "Studies have shown that hearing loss among the elderly is associated with a range of psychosocial as well as physical problems (Clark et al., 2012; Dalton et al., 2003; Hogan et al., 2009; Kramer et al., 2002; Wong and Cheng, 2012). The prevalence of hearing loss was 68.7% in a South Australian elderly population (aged ≥ 60 years) and 58.6% in a British population, where 13.5 and 13.8%, respectively, had a loss that was ≥45 dB HL (Wilson et al., 1999). A similar situation exists in Hong Kong, with 75.9% of elderly individuals having hearing loss, 37.1% having a more than moderate degree of loss, and 19.2% individuals with hearing impairment experiencing symptoms of depression (Chinese University of Hong Kong: Institute of Human Communicative Research, 2005).

    ABSTRACT: Hearing loss occurs most frequently within the elderly population, and having a hearing loss can adversely impact the quality of life of an individual. There is a need for detection of hearing loss at an early stage, and therefore elderly hearing screening programs are important. The efficacy of using distortion product otoacoustic emissions (DPOAEs) as a stand-alone objective hearing screening tool in comparison to conventional, behavioral pure-tone screening in community centers for the elderly in Hong Kong was investigated. Background noise was measured at each center, and the range of overall noise levels was from 42 to 53 dBA. DPOAE results were analyzed using six different pass/refer criteria, having stimuli concentration in the low, mid, or high frequencies, and based upon both absolute distortion product amplitude and signal-to-noise ratio (SNR; stricter criterion) or SNR alone (looser criterion). Kappa statistics of weighted agreement and observed agreement were calculated to compare DPOAE measures with pure-tone screening for 223 elderly participants. The highest observed agreement between pure-tone screening and DPOAE was found for a protocol with a focus on mid-frequency stimuli using a looser criterion. However, the highest agreement obtained was only fair, with agreement occurring at only 14% more than chance. Background noise in community centers for the elderly adversely affected the DPOAE measurements and DPOAE screening could not be considered as an effective stand-alone hearing screening tool for an elderly population attending urban community centers.

    • "Self-report of hearing difficulties, using questionnaire instruments or often only one or two questions, has commonly been used to assess the prevalence of hearing loss in large epidemiological studies [14], [26]. Some studies [14], [27] have reported the relationship of self-report with audiometric measures but only rarely have self-report data been validated against standard audiometric measures [28]–[30]. Self-report assessed by a single question (‘Do you feel you have a hearing loss?’) has been reported to demonstrate high sensitivity and specificity. "

    ABSTRACT: Background: Healthy hearing depends on sensitive ears and adequate brain processing. Essential aspects of both hearing and cognition decline with advancing age, but it is largely unknown how one influences the other. The current standard measure of hearing, the pure-tone audiogram is not very cognitively demanding and does not predict well the most important yet challenging use of hearing, listening to speech in noisy environments. We analysed data from UK Biobank that asked 40-69 year olds about their hearing, and assessed their ability on tests of speech-in-noise hearing and cognition.

    ABSTRACT: The cochlear implant provides auditory cues to profoundly deaf patients by electrically stimulating the residual spiral ganglion neurons. These neurons, however, undergo progressive degeneration after hearing loss, marked initially by peripheral fibre retraction and ultimately culminating in cell death. This research aims to use gene therapy techniques to both hold and reverse this degeneration by providing a sustained and localised source of neurotrophins to the deafened cochlea. Adenoviral vectors containing green fluorescent protein, with or without neurotrophin-3 and brain derived neurotrophic factor, were injected into the lower basal turn of scala media of guinea pigs ototoxically deafened one week prior to intervention. This single injection resulted in localised and sustained gene expression, principally in the supporting cells within the organ of Corti. Guinea pigs treated with adenoviral neurotrophin-gene therapy had greater neuronal survival compared to contralateral non-treated cochleae when examined at 7 and 11 weeks post injection. Moreover; there was evidence of directed peripheral fibre regrowth towards cells expressing neurotrophin genes after both treatment periods. These data suggest that neurotrophin-gene therapy can provide sustained protection of spiral ganglion neurons and peripheral fibres after hearing loss.
