Deterioration in speech intelligibility, the most common complaint of people with hearing loss, leads to social isolation and dramatically reduces the quality of life. The correction of peripheral hearing loss by hearing aid fitting does not always solve this problem in patients with chronic sensorineural hearing loss (SNHL). That is why in the process of audiological examination of patients with complaints of hearing loss, it is necessary to include methods of speech audiometry, which make it possible to comprehensively assess the functioning of the auditory system. The aim of the study: assessment of speech intelligibility in patients of different ages with SNHL. 94 people from 20 to 74 years of age were examined: 54 patients with SNHL (14 young and 40 elderly) and 40 people with normal hearing thresholds (20 young and 20 elderly). Besides the standard audiological examination, speech audiometry testing was conducted: evaluation of monosyllabic words intelligibility in quiet, binaural rapidly alternating speech test, dichotic digits test, Russian matrix sentence test (RuMatrix). Results: Speech intelligibility in elderly patients with SNHL was shown to be significantly worse than in young patients with a similar degree of hearing loss. The RuMatrix test in noise was proved to be the most sensitive test for comprehensive evaluation of the hearing system functioning.

Pathophysiologic Mechanism

Objectives: Norrie disease is an X-linked recessive disorder in which patients are born blind and develop sensory hearing loss in adolescence. The hearing loss associated with Norrie disease has been shown in a genetically altered knockout mouse to involve dysfunction of the stria vascularis; most other structures are preserved until the later stages of the disease. The objective of this study was to characterize the audiologic phenotype of Norrie disease for comparison with the pathophysiologic mechanism. Methods: The design combined two series of clinical audiologic evaluations, with special attention to speech intelligibility. Results: The audiologic results for 12 affected individuals and 10 carriers show that patients with Norrie disease retain high speech intelligibility scores even when the threshold loss is severe. Conclusions: The cochlear mechanism — failure of the stria vascularis — accounts for some of the higher values in the wide distribution of speech scores in cases with similar pure tone audiograms.

Objectives -to determine the normative data of sentence speech intelligibility in a free sound field and to estimate the applicability of the Russian Matrix Sentence test (RuMatrix) for assessment of the hearing aid fitting benefit. Material and methods. 10 people with normal hearing and 28 users of hearing aids with moderate to severe sensorineural hearing loss were involved in the study. RuMatrix test both in quiet and in noise was performed in a free sound field. All patients filled in the COSI questionnaire. Results. The hearing impaired patients were divided into two subgroups: the 1st with high and the 2nd with low hearing aid benefit, according to the COSI questionnaire. In the 1st subgroup, the threshold for the sentence intelligibility in quiet was 34.9 ± 6.4 dB SPL, and in noise -3.3 ± 1.4 dB SNR, in the 2nd subgroup 41.7 ± 11.5 dB SPL and 0.15 ± 3.45 dB SNR, respectively. The significant difference between the data of both subgroups and the norm was registered (p

The purpose of this study was twofold: (a) to determine the extent to which 4-channel, slow-acting wide dynamic range amplitude compression (WDRC) can counteract the perceptual effects of reduced auditory dynamic range and (b) to examine the relation between objective measures of speech intelligibility and categorical ratings of speech quality for sentences processed with slow-acting WDRC. Multiband expansion was used to simulate the effects of elevated thresholds and loudness recruitment in normal hearing listeners. While some previous studies have shown that WDRC can improve both speech intelligibility and quality, others have found no benefit. The current experiment shows that moderate amounts of compression can provide a small but significant improvement in speech intelligibility, relative to linear amplification, for simulated-loss listeners with small dynamic ranges (i.e., flat, moderate hearing loss). This benefit was found for speech at conversational levels, both in quiet and in a background of babble. Simulated-loss listeners with large dynamic ranges (i.e., sloping, mild-to-moderate hearing loss) did not show any improvement. Comparison of speech intelligibility scores and subjective ratings of intelligibility showed that listeners with simulated hearing loss could accurately judge the overall intelligibility of speech. However, in all listeners, ratings of pleasantness decreased as the compression ratio increased. These findings suggest that subjective measures of speech quality should be used in conjunction with either objective or subjective measures of speech intelligibility to ensure that participant-selected hearing aid parameters optimize both comfort and intelligibility.

Auditory Disorders

Audiologists and acoustical engineers have urged that acoustics be considered in the design of classrooms for more than 30 years. Research has demonstrated that children with hearing loss have great difficulty understanding speech in noisy, reverberant environments. However, there has never been a legal mechanism to require local educational systems to address acoustics in the design and construction of schools. An effort by a broad-based coalition of engineers, audiologists, parents, architects, and educators is now underway to develop a standard for acoustics that would then be referenced in the Americans with Disabilities Act (ADA). Although the legal mechanism for this action is to address the needs of children with disabilities as the ADA requires (most notably, children with hearing impairments, but also those with central auditory disorders, attention deficit disorders, and vision impairments), the impact will be more far-reaching. All children—whether or not they have a disability—will benefit from a favorable acoustical environment.
