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.

The Impact

Relevance: Any kind of the hearing loss, especially in the childhood, affects the mental and intellectual development negatively as well as behavior and social position of a deaf patient in the hearing world. Cochlear implantation is the most effective and reliable method of medical and educational auditory-speech rehabilitation for both adults and children with severe hearing loss and deafness. One of the key performance indicators of the cochlear implantation is a result of speech audiometry, especially on the noise background. The aim is to study the state of auditory function according to the subjective audiometry in the noise background and the influence of various factors on the effectiveness of rehabilitation of the children after cochlear implantation. Materials and methods: The study involved 150 children with severe sensorineural hearing loss and deafness after cochlear implantation. In age, they ranged from 3 to 18 years old. Evaluation of the efficiency of cochlear implantation was carried out in several stages. All studies were done in the free-field with the cochlear implant on. At first, we performed the pure tone audiometry. Then we defined the 50% intelligibility threshold of numeral test. After that, we defined a word recognition percentage. And finally we defined the impact of masker on speech intelligibility at SPL of useful signal 50, 60 and 80 dB. Results: Based on the analysis of the received data, all children with severe sensorineural hearing loss and deafness after cochlear implantation were divided into 3 groups depending on the speech intelligibility. The first group (high efficiency of cochlear implantation) included 68 children (45,3%). This group was divided into two subgroups depending on the difference between the values of the speech intelligibility in the free sound field and in the noise background. The second group (average efficiency) consisted of 45 children (30%). The third group (low efficiency) were 37 children (24,7%). The influence of various factors on the efficiency of cochlear implantation was analyzed. Conclusion: Speech intelligibility in the noise background must be examinated in all children after cochlear implantation. The main factors affecting the effectiveness of cochlear implantation according to test of speech intelligibility in the noise background are the ethiology of hearing loss and duration of post-operation period. Results of speech intelligibility in the noise background test will help specialists who practice the rehabilitation of children after cochlear implantation (teachers for deaf, speech therapists) to pay attention to the decrease of speech intelligibility in children in the real conditions of communication and to focus their efforts on its improving with the appropriate methods.

Volume Doubling

Progressive sensorineural hearing loss is the most important early symptom of a cerebellopontine angle process. A case report is presented of a 42-year-old woman who was referred to our department in 1979. Oil cistemography showed non filling of the left internal acoustic canal. Audiometry was planned as the method of control, but she did not return until nine- years later. In 1988, an acoustic neurionoma of 4 cm diameter was found in the left CPA. Pure tone audiometry and speech audiometry showed that during the nine-year interval, her 60 dB flat sensorineural hearing loss and speech perception thresholds had remained almost unchanged. A follow-up with only tone and speech audiometry can lead to a false negative diagnosis in some of these cases. Calculation of the growth in tumour volume over nine years in this patient showed a tumour volume doubling time of about 15 months.

Temporal Location

AbstractTwo previous experiments from our laboratory with 70 interrupted monosyllabic words demonstrated that recognition performance was influenced by the temporal location of the interruption pattern. The interruption pattern (10 interruptions/sec, 50% duty cycle) was always the same and referenced word onset; the only difference between the patterns was the temporal location of the on- and off-segments of the interruption cycle. In the first study, both young and older listeners obtained better recognition performances when the initial on-segment coincided with word onset than when the initial on-segment was delayed by 50 msec. The second experiment with 24 young listeners detailed recognition performance as the interruption pattern was incremented in 10-msec steps through the 0- to 90-msec onset range. Across the onset conditions, 95% of the functions were either flat or U-shaped.To define the effects that interruption pattern locations had on word recognition by older listeners with sensorineural hearing loss as the interruption pattern incremented, re: word onset, from 0 to 90 msec in 10-msec steps.A repeated-measures design with ten interruption patterns (onset conditions) and one uninterruption condition.Twenty-four older males (mean = 69.6 yr) with sensorineural hearing loss participated in two 1-hour sessions. The three-frequency pure-tone average was 24.0 dB HL and word recognition was ≥80% correct.Seventy consonant-vowel nucleus-consonant words formed the corpus of materials with 25 additional words used for practice. For each participant, the 700 interrupted stimuli (70 words by 10 onset conditions), the 70 words uninterrupted, and two practice lists each were randomized and recorded on compact disc in 33 tracks of 25 words each.The data were analyzed at the participant and word levels and compared to the results obtained earlier on 24 young listeners with normal hearing. The mean recognition performance on the 70 words uninterrupted was 91.0% with an overall mean performance on the ten interruption conditions of 63.2% (range: 57.9–69.3%), compared to 80.4% (range: 73.0–87.7%) obtained earlier on the young adults. The best performances were at the extremes of the onset conditions. Standard deviations ranged from 22.1% to 28.1% (24 participants) and from 9.2% to 12.8% (70 words). An arithmetic algorithm categorized the shapes of the psychometric functions across the ten onset conditions. With the older participants in the current study, 40% of the functions were flat, 41.4% were U-shaped, and 18.6% were inverted U-shaped, which compared favorably to the function shapes by the young listeners in the earlier study of 50.0%, 41.4%, and 8.6%, respectively. There were two words on which the older listeners had 40% better performances.Collectively, the data are orderly, but at the individual word or participant level, the data are somewhat volatile, which may reflect auditory processing differences between the participant groups. The diversity of recognition performances by the older listeners on the ten interruption conditions with each of the 70 words supports the notion that the term hearing loss is inclusive of processes well beyond the filtering produced by end-organ sensitivity deficits.

Monosyllabic Words

Characteristics of the range of intensities yielding PB Max and of the threshold for monosyllabic words (PBT) were investigated in 110 elderly subjects with mild-to-moderate sensorineural hearing loss. Word recognition functions were generated using the Auditec recordings of the CID W-22 words with 50 words per level. The results indicated that (a) the range of intensities yielding PB Max was approximately 33 dB at a level corresponding to 12% below PB Max, (b) the PB Max range decreased as the magnitude of hearing loss increased, (c) testing at the loudness discomfort level was likely to provide a more accurate estimate of PB Max than testing at most comfortable listening level, (d) word recognition scores should be obtained at a minimum of two intensities in order to estimate PB Max, (e) the PBT in dB SL re the spondaic threshold increased as the steepness of the audiogram increased, and (f) the PBT should not be considered unusual unless it exceeds the predicted value by about 14 dB.

Background and Objectives: This study aimed to compare functional hearing with the use of a personal sound amplification product (PSAP) or a basic hearing aid (HA) among sensorineural hearing impaired listeners.Subjects and Methods: Nineteen participants with mild-to-moderate sensorineural hearing loss (SNHL) (26-55 dB HL; pure-tone average, 0.5-4 kHz) were prospectively included. No participants had prior experience with HAs or PSAPs. Audiograms, speech intelligibility in both quiet and noisy environments, speech quality, and preference were assessed in three different listening conditions: unaided, with the HA, and with the PSAP. Results: The use of PSAP was associated with significant improvement in pure-tone thresholds at 1, 2, and 4 kHz compared to the unaided condition (all <i>p</i> <0.01). In the quiet environment, speech intelligibility was significantly improved after wearing a PSAP compared to the unaided condition (<i>p</i> <0.001), and this improvement was better than the result obtained with the HA. The PSAP also demonstrated similar improvement in the most comfortable levels compared to those obtained with the HA (<i>p</i> <0.05). However, there was no significant improvement of speech intelligibility in a noisy environment when wearing the PSAP (<i>p</i> =0.160). There was no significant difference in the reported speech quality produced by either device or in participant preference for the PSAP or HA. Conclusions: The current result suggests that PSAPs provide considerable benefits to speech intelligibility in a quiet environment and can be a good alternative to compensate for mild-to-moderate SNHL.

Introduction. There are many methods for treating sensorineural hearing loss (SHL) of the occupational origin, which indicates insufficient effectiveness and an active search for more advanced therapy methods. Objective of the study: to evaluate changes in the state of the central nervous system pathways under the influence of a magnetic field and the long-term period. Materials and Methods. There were treated fifty two aviation workers with SHL of the occupational origin with moderate hearing loss. Pulsed magnetic stimulation (MS) and pneumatic massage of the tympanic membrane were used. Before and after treatment, electroencephalography was performed with the registration of visual and auditory evoked potentials (EP), somatosensory evoked potentials (SSEP), psychological testing, and the study of higher mental functions in terms of short-term and delayed verbal memory, attention function. Results. After treatment, there was an improvement in speech intelligibility in 62% of cases, a decrease in the intensity of the tinnitus and head noise in 44% of cases, there was an improvement in the indicators of audiometric research and acumetry data from both sides. There was a statistically significant increase in the α-rhythm, the time of the pulse passing through the central afferent structures increased, the indicators of operative verbal memory, and the productivity of long-term memorization, the volume and stability of attention increased. Conclusion. The effectiveness of pulse MS in treating patients with occupational SHL has been proven. The prospects of using pulsed MS in combination with pneumatic massage in occupational pathology were shown, which was confirmed by positive changes in objective and subjective indicators characterizing the condition of patients immediately after the therapy sessions and a year after treatment.

Objectives to improve the quality of hearing aids (HA) selection for patients with sensorineural hearing loss using a comparative free sound field speech audiometry according to our modified method "Delta Test". Material and methods. The study involved 56 patients aged from 18 to 62 years with bilateral chronic sensorineural hearing loss of 2-4 degrees. The study group included 32 patients, a test for speech recognition in a free sound field (speech audiometry) was conducted using the method proposed by us. The control group consisted of 24 patients who were aided without the use of comparative speech audiometry. The "Delta Test" included the use of audio files sets containing a speech material in pure form and mixed with speech noise with different signal-to-noise ratios, supplied through a speaker system connected to a personal computer. The percentage of correctly repeated words was measured without HA and with several HA having different settings. The effectiveness of using HA was defined as the difference in the percentage of speech recognition when using HA in relation to the "ear without HA". Results. According to "The International Outcome Inventory for Hearing Aids" the average score was 4.13 0.10 in the group where the HA were selected using the "Delta Test", which is statistically significantly higher than in the control group, where the average score was 3.720.15(p 0.05). "Delta Test" allows optimally select the HA parameters. This method is easy to perform and does not require expensive equipment.
