Sentence Intelligibility

A sentence intelligibility test was used to evaluate listener performance with three hearing aids differing substantially in physical characteristics. Thirty six hard-of-hearing listeners, representing various types and degrees of hearing loss, were tested. Results showed that, although the sentence intelligibility test reflected meaningful average differences among the aids, the rank ordering of aids was essentially equivalent for all listeners.

Continuous Noise

Most studies of the effects of noise upon hearing have dealt with continuous noise exposure. Previous reports on intermittent exposure to noise concluded that it causes less damage to hearing than does continuous exposure to noise of the same intensity. In this investigation, 12,000 workers were screened to find 295 subjects who met the strict criteria of the study. Most of the subjects were exposed to jackhammer noise at peak levels of 118 dBA. Intermittent exposure to intense noise results in very severe loss in high frequencies but relatively little or no hearing loss in the lower frequencies even after many years of exposure. This differs substantially from the effects of continuous exposure to noise of the same intensity. It remains to be determined whether this pattern of hearing results from intermittent exposure to all sorts of noise or only from the kinds of sources investigated in this study.

Purpose This study examined how frequency lowering affected sentence intelligibility and quality for adults with postlingually acquired, mild-to-moderate hearing loss. Method Listeners included adults aged 60–92 years with sloping sensorineural hearing loss and a control group of similarly aged adults with normal hearing. Sentences were presented in quiet and babble at a range of signal-to-noise ratios. Intelligibility and quality were measured with varying amounts of frequency lowering, implemented using a form of frequency compression. Results Moderate amounts of compression, particularly with high cutoff frequencies, had minimal effects on sentence intelligibility. Listeners with the greatest high-frequency hearing loss showed the greatest benefit. Sentence intelligibility decreased with more compression. Listeners were more affected by a given set of parameters in noise than in quiet. In quiet, any amount of compression resulted in lower speech quality for most listeners, with the greatest degradation for listeners with better high-frequency hearing. Quality ratings were lower with background noise, and in noise, the effect of changing compression parameters was small. Conclusions The benefits of frequency lowering in adults were affected by the compression parameters as well as individual hearing thresholds. The data are consistent with the idea that frequency lowering can be viewed in terms of improved audibility versus increased distortion trade-off.

Research Objects

For many years, morbidity with work-related diseases has been higher in Chukotka Autonomous Area (ChAA) than on average in Russia. Our research objects were working conditions and morbidity with work-related diseases. Our research goal was to examine reasons for work-related pathology occurrence, its structure, and prevalence in ChAA in 2008–2018. We examined data obtained via social-hygienic monitoring in 2008–2018 in Chukotka, paying close attention to a section entitled «Working conditions and work-related pathology». We established that noise (17.4%) and cooling microclimate (11.8%) were the most widely spread hazardous occupational factors in ChAA. 20.1% workers were exposed to a combination of hazardous factors. 13.5% workers were employed at industrial objects that belonged to the 1st surveillance group (the highest risks); 31.9% worked at economic entities from the 3rd surveillance group (average risks). In 2008–2018 216 work-related diseases were first diagnosed in Chukotka, mostly among workers employed at mining enterprises (81.5%). Sensorineural hearing loss / noise effects in the internal ear (35.2%) and respiratory diseases (31.9%) prevailed in their structure. 73.6% diseases were detected due to patients applying for medical aid themselves. In 2008–2015 there was a steady growth in work-related morbidity (from 1.94 to 13.5 per 10,000 workers), but there was a decrease in it in 2016–2018 (down to 5.11 per 10,000 workers) with considerable fluctuations in numbers of first diagnosed diseases. Risks of work-related pathology occurrence were higher in Chukotka in 2018 than in 2008: OR=2.37; CI 1.82–3.09; χ2=43.8; р<0.001. To prevent work-related pathology in Chukotka, it is necessary to continue activities aimed at working conditions improvement, in particular, reducing exposure to noise and aerosols with predominantly fibrogenic effects in mining industry in the region.

Sentence Intelligibility

A sentence intelligibility test and three monosyllabic word intelligibility tests, recorded through three hearing aids, were presented to 36 subjects with diverse types of hearing loss. Although hearing aids were rank ordered meaningfully on the sentence intelligibility test-in inverse proportion to the harmonic distortion-performance differences were not systematically reflected in the monosyllabic word test results.
