The Auditec recordings of the CID W-22 monosyllables were used to generate test and retest intelligibility functions on normally hearing listeners and subjects with mild-to-moderate sensorineural hearing loss. The normally hearing subjects were tested with 50-word lists at SPLs ranging from 15 to 50 dB. Lists of 25 words were used with the hearing-impaired group. The functions were analyzed to assess the reliability of threshold (50% point), slope (20%–80% points), and maximum intelligibility (PB max). The 50% point was obtained at 28 dB SPL for the normally hearing listeners and at a sensation level (SL) of 12 dB re spondaic thresholds for the hearing-impaired group. Very stable monosyllabic thresholds were found because 95% of the test-retest values were within 6 dB for both subject groups. Slopes of 4.9% per dB and 2.7% per dB were obtained for the normally hearing and hearing-impaired groups, respectively. Fair reliability was observed; 95% of the test-retest values encompassed a range of ± 1.9% per dB for the normally hearing subjects and ± 1.1% per dB for the hearing-impaired group. Although group slopes provide useful information for selecting the range and step size for generating psychometric functions, the value of routinely obtaining slope on an individual basis has not been demonstrated. Even though the same word lists were used for both test and retest measurements, reliability closely agreed with predicted results based on the binomial theorem. In contrast to the large variability for a single list of 25 words, very stable PB max scores were found when two or three scores were averaged on the plateau of the function.

The present study investigates the acoustic characteristics of Greek vowels produced by hearing-impaired children with profound prelingual hearing loss and cochlear implants. The results revealed a significant difference between vowels produced by hearingimpaired children and those produced by normal-hearing ones in terms of duration. Stressed vowels were significantly longer than non-stressed for both groups, while F0, F1 and F2 did not differ significantly between the two groups for any vowel, with the exception of /a/, which had significantly higher F1 when produced by hearingimpaired children. Acoustic vowel spaces were similar for the two groups but shifted towards higher frequencies in the low-high dimension and somehow reduced in the front-back dimension for the hearing-impaired group.

Random Survey

The purpose of this paper is to study the prevalence rate of hearing impairment among children with siblings and family members having hearing and speech disorders. A random survey of 6,421 Saudi infants and children between 2 months and 12 years of age was conducted in the Riyadh area. Children with no or few siblings and those who were firstborn were at relatively higher risk, and there was a strong association between children in the hearing-impaired group among those having living siblings with deafness. Those children who had family members with hearing and speech problems were at twice the risk of their counterpart groups regarding hearing impairment.

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.

Weighted Prevalence

This study was conducted using the database of the Korea National Health and Nutrition Examination Survey to determine whether age-related eye diseases such as cataract, glaucoma, diabetic retinopathy (DR), and age-related macular degeneration (AMD), are related to hearing loss. 12,899 participants ≥ 40 years of age were included. The weighted prevalence of diabetic retinopathy was not significantly different between the normal hearing group and hearing-impaired group, but the weighted prevalences of cataract, glaucoma, early AMD, and late AMD were significantly different in the two groups. The odds ratio for cataract in the hearing-impaired group was 1.373 (1.118–1.687). The odds ratios of glaucoma, DR, early AMD, and late AMD were not significantly different in the hearing-impaired group. Age was significantly associated with the presence of concurrent cataract and hearing impairment by 6.574-fold per decade. Significant factors that increased the risk of concurrent glaucoma and hearing impairment were age, male gender, and triglyceride. Age, ex-smoker, systolic BP elevation, BMI decline, and fasting blood sugar significantly predicted the presence of concurrent DR and hearing loss. In early AMD, age and triglyceride, and in late AMD, age and systolic BP elevations increased the risk of concurrent AMD and hearing impairment.

Conventional Manner

Some variables affecting the slope of monosyllabic word functions were investigated among subjects having mild-to-moderate sensorineural hearing loss. Slope is an important variable because it determines the intensity range and the step size that is likely to accurately and efficiently describe the function. Eighty-one ears from 60 elderly subjects were tested with the Auditec recording of the CID W-22 words. Slopes were computed between the 20 and 80% intelligibility points from the individual functions. The results indicated that the magnitude of hearing loss did not affect the slope of the intelligibility function. That is, slopes remained at approximately 3% per dB even though spondaic thresholds varied over a 45-dB range (15-60 dB HTL). The audiometric configuration was found to affect slope, although this relationship was weak (r=.30). As the audiogram progressed from flat to steeply falling, the slope decreased from about 3.5% per dB to 2.5% per dB. With subjects having flat and falling audiograms, slope was steeper for the 20-50% intelligibility segment (4.3% per dB) than for the 50-80% interval (2.9% per dB). These subjects also exhibited substantial differences in mean slope, depending on the procedure selected for computations. The mean of individual slopes was steepest (3.3% per dB), whereas the mean slope was only 2.4% per dB when computed from the function derived in the conventional manner by averaging intelligibility scores at fixed intensities.

Rate Of Speech

Hearing loss results in disruption of coordination in muscles and structures engaged in speech timing tasks and consequently acquisition of speech sounds is affected. The purpose of this study is to investigate and compare the speed and intelligibility of speech in hearing impaired and normal hearing Persian speaking elementary school boys and girls. 33 hearing impaired students are randomly selected from three hearing impaired groups (profound, severe and moderately-severe) and compared with 60 normal hearing students. The speed of speech was measured according to reading Words Per Minute (WPM), and speech intelligibility was tested by a 5-rank scale method. As expected, the normal hearing had more speed and intelligibility of speech in contrast to the hearing impaired group. Also hearing impaired boys had a better speed and intelligibility of speech compared to hearing impaired girls but in normal hearing group, girls had better speed. The amount of P-value for moderately-severe and sever hearing impaired was 0.006 and this amount for profound and moderately-severe hearing impaired was 0.002, so p-value is <0.05 and significantly important. Profound hearing impaired group read the text more slowly and had lower speech intelligibility than other two hearing impaired groups.

AbstractThirty families in which there were 149 individuals affected by the Waardenburg syndrome (WS) were investigated for penetrance of hearing loss and pigmentary abnormalities. Twenty two families contained 89 individuals affected by WS Type II and eight families with 60 individuals affected by Type I. A bilateral symmetrical sensorineural hearing loss was found to be the most common type of hearing loss. The most frequent degree of hearing loss category was a hearing loss of > 100dB HL with no difference between syndrome types.Although there was no significant difference in the frequency of pigmentation disorders between Type I and II, considering these abnormalities as a whole, heterochromia irides was more common in Type II than Type I and other pigmentation disorders were more frequent in Type I: 62 per cent of Type I patients had more than one pigmentary defect, but only 28 per cent of Type II. Pigmentary disturbances were not significantly more frequent in the hearing impaired group than in the normally hearing group in either Type I or II when taking into account the occurrence of only one pigmentation disorder. There was a significantly higher proportion of pigmentary defects in the hearing impaired group with Type I when only those having more than one pigmentary abnormality were compared: 93.3 per cent of Type I patients and 88.5 per cent of Type II patients with a profound hearing loss had pigmentary defects. The frequency of pigmentation disorders was not greater when the hearing loss was more severe in either type. Penetrance for hearing loss and pigmentary abnormalities showed marked intrafamilial and interfamilial variation.

The Auditec recordings of the CID W-22 and NU-6 word lists were administered to 30 adults having sensorineural hearing losses. Speech discrimination scores for both tests were obtained at 16, 24, and 32 dB sensation level. Results suggest that both tests differentiate sensorineural-impaired subjects from normal listeners, although scores were significantly better for the W-22 word lists at all sensation levels. Implications for the clinical use of these measures are discussed.

The teachers of 2231 elementary school children were asked to identify those with known or suspected hearing problems. Following screening, the data were compared. Teachers identified 5% of the children as hearing-impaired, while screening identified only 3%. There was agreement between the two procedures on 1%. Subsequent to the teacher interviews, rescreening and tympanometry were conducted. These procedures indicated that teacher screening and tympanometry were in agreement on 2% of the total sample or 50% of the hearing-loss group. It was concluded that teachers could supplement audiometry, particularly when otoscopy and typanometry are not available.

Binaural auditory fusion of 108 children (4, 6, and 8 years old) was studied using three lists of monosyllabic words (WIPI) presented at two sensation levels (30 and 40 dB). The words were processed to produce three bandwidth conditions (100, 300, 600 Hz) and were administered via three presentation modes (binaural fusion 1, diotic, binaural fusion 2). Results showed improved discrimination scores with increasing age, sensation level, and filter bandwidth. Diotic scores were better than binaural fusion scores for the narrower bandwidth conditions, but the diotic enhancement effect was seriously compromised in the widest bandwidth (600 Hz) condition. The results confirmed the contention that prior research results were equivocal due, in large measure, to procedural variability. Methods for reducing such variability and enhancing the clinical viability of binaural fusion tasks are suggested.
