Background: to research the level of hearing sensitivity among people of different age groups with normal hearing ability or with hearing impairment. Methods: the results of hearing test of people of different age groups and those of sociological survey are presented here. Result: 66% of examined have no anomalies of hearing ability, 16% of examined showed results, ranging from 75 to 85 percent of normal, hearing level of 18% of examined is ranged from 60 to 70 percent of normal. Conclusion: hearing impairment is caused by enhanced level of sound pressure, loss of hearing acuity is caused by ageing.

Thresholds for frequency modulation were measured by an adaptive, two-alternative, forced-choice method with ten listeners: eight who showed varying degrees of sensorineural hearing impairment, and two with normal-hearing sensitivity. Results for test frequencies spaced at octave intervals between 125 and 4000 Hz showed that, relative to normal-hearing listeners, the ability of the hearing-impaired listeners to detect a sinusoidal frequency modulation: (1) is diminished above a certain level of hearing loss; and (2) is more disrupted for low-frequency tones than for high-frequency tones, given the same degree of hearing loss at the test frequency. The first finding is consistent with that of previous studies which show a general deterioration of frequency-discrimination ability associated with moderate, or worse, hearing loss. It is proposed that the second finding may be explained: 1) by differential impairment of the temporal and place mechanisms presumed to, encode pitch at the lower and higher frequencies, respectively; and/or, 2) for certain configurations of hearing loss, by the asymmetrical pattern of cochlear excitation that may lead to the underestimation, from measurements of threshold sensitivity, of hearing impairment for low-frequency tones and consequently to relatively large changes in frequency discrimination for small shifts in hearing threshold.

We used a novel approach allowing participants in this study to self-monitor their hearing sensitivity to familiar sounds in the environment. The objective of this approach was to establish whether participants in the 80–89 and 90–99 age groups would recognize the degree of their hearing impairment. It was our hope that participants would value audiology treatment and that it would improve their quality of life over a short period. The pilot study took place in a clinical environment where participants answered survey questions before and after audiology treatment, which pertained to their hearing impairment, morale, social support, and life satisfaction. Caregivers were included in the research to rate and record participants’ problem behaviors (e.g., shouting, anger, agitation, repetitive speech dialog, and depression) before, during, and after treatment. This research validates other scientists’ findings that annoying problem behaviors may actually be the result of hearing loss because of a person’s inability to recognize speech. The pilot study shows that participants with mild dementia adapted well to speech and sounds in the natural environment without agitation as well as to management of hearing aids within a 30-day period. The participants with moderate dementia were slower to adapt. All participants with dementia required the cooperation of their caregivers to maintain hygiene of ear canals and hearing aids and insertion. This study suggests that the sooner people receive treatment for hearing loss, the quicker they are to recognize speech and to master hearing aid technology.

Evidence suggests that musicians may be more susceptible to developing a hearing impairment due to increased exposure to loud sounds over the lifespan. Hearing impairments can affect musical performance behaviours, yet research suggests they do not significantly affect ensemble synchrony unless the hearing loss is severe or profound. This study investigated the effect of reduced auditory feedback on ensemble synchrony, looking behaviour and playing level. Four violinists, with self-reported normal hearing, formed two duos in acoustically-isolated rooms separated by a glass window. Each player received feedback from their own and their co-performer’s playing attenuated by 0, 10, 20, 30 and 40 dB. Video recordings of their looking behaviours were coded and signed asynchronies were identified in the audio files. The strongest effects found were bi-directional changes to playing levels as a result of auditory feedback levels, which increased when a player’s own feedback was reduced and reduced when co-performer feedback was attenuated. Violinists’ looking behaviour was found to increase when co-performer feedback was attenuated by 20 dB or more relative to their own, such that they glanced more frequently and looked for longer towards their partners. There were no effects of auditory attenuation on ensemble synchrony, even with 40 dB attenuation. The results indicate that “self-to-other” sound level ratios are more likely to prompt compensatory musical performance behaviours than an individual’s hearing ability.

BACKGROUND eHealth and social media could be of particular benefit to hearing impaired adults but little is known about their use of smart devices, apps and social media. OBJECTIVE To study if adults with normal hearing and those with impaired hearing differ in: weekly use of smart devices, apps and social media; reasons for using social media; and benefits from using social media. METHODS Data from a Dutch cohort, the National Longitudinal Study on Hearing (NL-SH), were used. Data were collected between 1 October 2016 and 1 April 2020, using an online questionnaire and hearing test. Normal hearing adults (N=341) and those with hearing impairment (N=384) were categorized based on the hearing test. Results were compared using (multiple) logistic regression models. RESULTS Hearing impaired adults did not differ from normal hearing adults in their use of a smartphone or tablet. They were less likely to make use of social media apps on a smartphone, tablet or smartwatch (age-adjusted OR 0.67, 95% CI 0.48 - 0.92, P=.015) but not less likely to use social media on all types of devices (age-adjusted OR 0.90, 95% CI 0.57 - 1.41, P =.65). Use of other apps did not differ. Hearing impaired adults were more likely to use social media to stay in touch with family members (OR 1.54, 95% CI 1.16 - 2.07, P =.003) and with friends (age-adjusted OR 1.35, 95% CI 1.01 - 1.81, P=.046). Furthermore, they were more likely to use social media to perform their work (age-adjusted OR 1.51, 95% CI 1.04 - 2.18, P=.029). There were no differences in experienced benefits from social media. CONCLUSIONS The potential for eHealth is confirmed as hearing impaired adults are not less likely to use smart devices than their normal hearing peers. Nevertheless, a substantial number of elderly people accesses the internet by other means. To ensure equal access to digital hearing healthcare it has to be available on other devices as well. Hearing impaired adults are less likely to make use of social media apps on a smart device but not less likely to use social media on all types of internet-connected devices. This warrants further research of the types of social media platforms hearing impaired adults use and on which device they prefer to use them. Hearing impaired adults used social media to greater degree to stay in touch with family members and friends, but this did not result in closer/more intense family ties or friendships. Given that hearing impaired participants are more likely than their normal hearing peers to use social media to perform their work, further work could be done on vocational rehabilitation services using social media.

AbstractSeventeen unrelated Danish patients with Pendred's syndrome, whose case stories have not been published previously, are presented. Acoustic and vestibular functions were examined and endocrinological screening was performed. There was a great variation in hearing ability as well as in thyroid function. Furthermore, in contrast to previous investigations, normal caloric function was demonstrated in the majority. In all patients a Mondini malformation was demonstrated. On the basis of this investigation it is concluded that: (1) the Mondini defect is part of Pendred's syndrome; (2) the inherited Mondini malformation is the underlying cause of the sensorineural hearing impairment; and (3) the hearing sensitivity varies greatly in these patients.

Real-time spectrographic displays (SDs) have been used in speech training for more than 30 years with adults and children who have severe and profound hearing impairments. Despite positive outcomes from treatment studies, concerns remain that the complex and abstract nature of spectrograms may make these speech training aids unsuitable for use with children. This investigation examined how well children with normal hearing sensitivity and children with impaired hearing can recognize spectrographic cues for vowels and consonants, and the ages at which these visual cues are distinguished. Sixty children (30 with normal hearing sensitivity, 30 with hearing impairments) in 3 age groups (6–7, 8–9, and 10–11 years) were familiarized with the spectrographic characteristics of selected vowels and consonants. The children were then tested on their ability to select a match for a model spectrogram from among 3 choices. Overall scores indicated that spectrographic cues were recognized with greater-than-chance accuracy by all age groups. Formant contrasts were recognized with greater accuracy than consonant manner contrasts. Children with normal hearing sensitivity and those with hearing impairment performed equally well.

This study examined the perceived intelligibility of synthetic speech. Participants were adults aged 49–69, one group with normal hearing and one group with acquired sensorineural hearing impairment. Word lists were presented in two speech types: DECtalk (a high-quality speech synthesizer) and a natural male speaker. Results revealed differences between groups, with normal-hearing listeners scoring higher than hearing-impaired listeners, and between speech types, with higher scores for natural speech than for synthesized speech. There was no significant interaction of hearing level and speech type.

Introduction: Traffic police are continually exposed to loud noise. The pure tone audiometric screening for hearing test has not been done in Biratnagar Nepal. So, we conducted a study to screen hearing ability and also to find out hearing thresholds among traffic police with normal hearing ability. Materials and methods: The study was conducted among 36 traffic police personnel. The 25dB sound was administered with audiometer (name) in different frequencies (1 kHz, 2 kHz, 3 kHz, 4 kHz and 8 kHz) for screening hearing loss in left and right ears. The threshold for hearing among normal hearing traffic personnel was compared with controls in all the frequencies. Result: Among 36 traffic police, 17(47.2%) had hearing loss. Maximum (n=8) hearing loss was seen in 4 kHz (4 - unilateral and 4 – bilateral) followed by 3 kHz (n=4, 3 unilateral and 1 bilateral) and mixed 3kHz and 4 kHz frequencies. The percentage of hearing loss in 2 kHz, 3 kHz and 4 kHz frequencies was more in left ear compared to right.  The threshold for hearing loss was higher in traffic police compared to controls .In the left ear, it was only in 4kHz {(25.91+6.64 Vs 20.45±4.15,( p=.034)} whereas in right ear, the threshold was higher in 3 kHz {20.45±5.22 Vs 15.91±4.90, (p=0.04)}, 4 kHz {25.45±12.54 Vs 16.82±5.60, (p=0.05)} and 8000 kHz {18.64±17.62 Vs 6.36±3.23, (p=0.04) . Conclusion: The hearing loss was present in 47.2% of traffic policemen predominantly in 4 kHz. The threshold for hearing was also higher among traffic police compared to controls.

A study of otologic and audiologic screening of preschool children including tympanometry, acoustic reflexes, and pure-tone screening was carried out at school sites. Subsequent pure-tone threshold tests and otolaryngologic examinations were carried out in a hospital setting. Complete data are available on 1,335 subjects, ages 3 through 5 years. Results are reported in comparison with those of an earlier Pittsburgh screening study.1 The results of the earlier study showed that loss of hearing sensitivity could not be predicted by the otologic findings, and conversely, the otologic findings could not be predicted by the air conduction thresholds. The results of the present study showed a contribution by tympanometry and acoustic reflexes. The results are evaluated in terms of screening effectiveness in these age groups. One of the recommendations combines an interpretation of certain large negative tympanometric peak pressures (TPP) along with the absence of acoustic reflexes to certain stimuli. The method is more efficient than other aspects of middle ear measurement or of pure-tone screening. The efficiency of each procedure is documented. Summary matrices are used to show the effectiveness of each test compared to all other tests in the identification of subjects with hearing or middle ear dysfunction. A protocol for screening evaluation and otologic referral is suggested to effect a balance between over-referral and correct identification.

Listeners with normal-hearing sensitivity recognize speech more accurately in the presence of fluctuating background sounds, such as a single competing voice, than in unmodulated noise at the same overall level. These performance differences are greatly reduced in listeners with hearing impairment, who generally receive little benefit from fluctuations in masker envelopes. If this lack of benefit is entirely due to elevated quiet thresholds and the resulting inaudibility of low-amplitude portions of signal + masker, then listeners with hearing impairment should derive increasing benefit from masker fluctuations as presentation levels increase. Listeners with normal-hearing (NH) sensitivity and listeners with hearing impairment (HI) were tested for sentence recognition at moderate and high presentation levels in competing speech-shaped noise, in competing speech by a single talker, and in competing time-reversed speech by the same talker. NH listeners showed more accurate recognition at moderate than at high presentation levels and better performance in fluctuating maskers than in unmodulated noise. For these listeners, modulated versus unmodulated performance differences tended to decrease at high presentation levels. Listeners with HI, as a group, showed performance that was more similar across maskers and presentation levels. Considered individually, only 2 out of 6 listeners with HI showed better overall performance and increasing benefit from masker fluctuations as presentation level increased. These results suggest that audibility alone does not completely account for the group differences in performance with fluctuating maskers; suprathreshold processing differences between groups also appear to play an important role. Competing speech frequently provided more effective masking than time-reversed speech containing temporal fluctuations of equal magnitude. This finding is consistent with "informational" masking resulting from competitive processing of words and phrases within the speech masker that would not occur for time-reversed sentences.
