Abstract We compared the experience of auditory hallucinations, in persons who have normal (HN; N = 20), or impaired hearing (HI; N = 20), while experiencing psychoses. We assessed this experience across 42 domains and observed that irrespective of the hearing status, patients most often heard voices mainly in the language that they had learnt first (χ2 = 5.584; P = .018). However, a few experienced hallucinations in languages they “did not know” (3/20; 15%). The voices were most often attributed to both males and females (35/40; 87.5%). Those with hearing impairment heard voices closer to their ears, a hubbub of voices of crowds talking to them, and “as if” stuck or repetitive; often in the hearing-impaired ear. The hearing-impaired subjects also reported hearing nonverbal auditory hallucinations more frequently (χ2 = 17.625; P = .001), and the voices lacked emotional salience (χ2 = 4.055; P = .044). In contrast, the hallucinations were experienced in elaborate detail by the HN (20/20), while those with HI often heard only simple sentences (14/20, P = 0.05). The intensity of the hallucinatory voices remained the same on closing the affected ear or both of the ears in the HI group as compared to the HN group. Interestingly, the use of hearing aids attenuated the intensity of the hallucinations (6/7; 85%) in those with HI.

This research paper expounds microcontroller based binaural digital hearing aids for hearing-impaired people by making use of ATmega328 microcontroller and other circuitries to process the audio signal input by either increasing or reducing the gain level of input audio signal, filter background noise, frequencies compression, save battery power and minimize circuit by making use of the internal ADC of the microcontroller and two PMW pins of the microcontroller as DAC. Hearing impairment among the youths and adults nowadays are in the increase, due wrong use of phones of which every minute of the day someone’s earphone is on listening to one type of music or the other. In other to solve the problem created so to say this research work was conceived and given birth to. The different stages of digital hearing aid are designed and then simulated first in Proteus software which then was implemented using PCB-board. The main components of this system were the audio input unit which consists of the microphone and its pre-amplifier, the microcontroller (ATmega328) which consists of the ADC, the DAC and the audio signal processing, the filter stage and control codes (frequencies compression codes, power saver codes, acoustic feedback control codes, signal level control and adaptive adjustment codes etc.), the power amplifier and volume control unit and then the earphones (output). The control codes were written in C language while Ardinuo Uno compiler was used to write the codes into ATmega328.  The prototype has an overall system gain of 27dB and the power output of 32.5mW. The prototype was tested with a patient that has a hearing impairment and the patient was satisfactory with the device. http://dx.doi.org/10.4314/njt.v36i3.34

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.

The Impact

Children with hearing deficits frequently have delayed motor development. The purpose of this study was to evaluate saccular function in children with hearing impairments using the Vestibular Evoked Myogenic Potential (VEMP). The impact of the saccular hypofunction on the timely maturation of normal balance strategies was examined using the Movement Assessment Battery for Children (Movement ABC). Thirty-three children with bilateral severe/profound hearing impairment between 4 and 7 years of age were recruited from a three-state area. Approximately half of the sample had one or bilateral cochlear implants, one used bilateral hearing aids, and the rest used no amplification. Parents reported whether the hearing impairment was diagnosed within the first year or after 2 years of age. No VEMP was evoked in two thirds of the hearing impaired (HI) children in response to the bone-conducted stimulus. Children who were reportedly hearing impaired since birth had significantly poorer scores when tested with the Movement ABC.

Aims: This study aims to assess the academic performance of children with hearing impairment who received early intervention in Lahore. Study Design:  Cross sectional survey design was used. Place and Duration of Study: Data was collected from Special Institute/School; Hamza foundation academy Lahore, Pakistan for the duration of six months from March 2021 to September 2021. Methodology: 97 students with moderate to severe sensorineural hearing loss children (aged in between 4 to 12), using hearing aids (HA’s) and cochlear implant (CI) were included by using purposive sampling technique. Hearing impaired children with other than sensorineural hearing loss and children who didn’t receive early intervention (hearing aids/implants or speech therapy) were excluded from this study. Results: It was found that 97 children with hearing impairment achieved significantly in their test score (80 to 99%) across English, Science, and Mathematics as compared to Urdu and Islamiyat (70 to 79%) after the implementation of intervention strategies. Conclusion: The study conclude that, while children with hearing impairment faced struggle in some areas of academics which includes listening and imitation in subjects like Urdu (structure of words) and Islamiyat (due to Arabic talafuz), their  academic performance in Math, English, and Science is higher with overall achieved percentage between  80 to 99%.

Hearing impairment and Latin are not usually something that we pair together, yet it could be seen as an appealing GCSE to a hearing-impaired student. On the one hand learning Latin as an additional language may be seen as difficult when the student is still trying to learn and develop their first language. On the other hand learning Latin does not have, nor require, any formal oral or aural assessment like most Modern Foreign Languages (MFL). My school is an 11-16 mixed comprehensive, where all pupils begin Latin in year 7 on timetable with the choice to continue in Year 8, from where it is taught as an off-timetable subject through to GCSE. Here I was introduced to teach a Year 10 boy who has congenital severe sensory-hearing loss in both ears and he wears two Nathos UP digital hearing aids all waking hours. I was immediately interested in his reasons for choosing to study Latin, especially as it is an elective GCSE timetabled before school and during lunch time. Prior to this encounter, I had recently attended a session on British Sign Language and the experience of Deaf and hearing-impaired students in school. Hearing about their experiences led me to think about the benefits of learning Latin, which consequently led me to investigate Kim's experience (name changed for confidentiality). I began focusing my observations on him and informally questioning his teachers; I was met by an array of praise stating that he proudly saw his hearing impairment as part of his identity rather than an obstacle. I started searching for information on teaching Latin to hearing-impaired pupils, but there was almost nothing specifically related to Latin. As a result, I saw this as my opportunity to collate my experiences and the experiences of the pupil and teacher to develop my research into something that may benefit other Latin teachers of hearing-impaired pupils.

Background: There are two cues that listeners use to disambiguate the front/back location of a sound source: high-frequency spectral cues associated with the head and pinnae, and self-motion–related binaural cues. The use of these cues can be compromised in listeners with hearing impairment and users of hearing aids. Purpose: To determine how age, hearing impairment, and the use of hearing aids affect a listener’s ability to determine front from back based on both self-motion and spectral cues. Research Design: We used a previously published front/back illusion: signals whose physical source location is rotated around the head at twice the angular rate of the listener’s head movements are perceptually located in the opposite hemifield from where they physically are. In normal-hearing listeners, the strength of this illusion decreases as a function of low-pass filter cutoff frequency, this is the result of a conflict between spectral cues and dynamic binaural cues for sound source location. The illusion was used as an assay of self-motion processing in listeners with hearing impairment and users of hearing aids. Study Sample: We recruited 40 hearing-impaired participants, with an average age of 62 yr. The data for three listeners were discarded because they did not move their heads enough during the experiment. Data Collection and Analysis: Listeners sat at the center of a ring of 24 loudspeakers, turned their heads back and forth, and used a wireless keypad to report the front/back location of statically presented signals and of dynamically moving signals with illusory locations. Front/back accuracy for static signals, the strength of front/back illusions, and minimum audible movement angle were measured for each listener in each condition. All measurements were made in each listener both aided and unaided. Results: Hearing-impaired listeners were less accurate at front/back discrimination for both static and illusory conditions. Neither static nor illusory conditions were affected by high-frequency content. Hearing aids had heterogeneous effects from listener to listener, but independent of other factors, on average, listeners wearing aids exhibited a spectrally dependent increase in “front” responses: the more high-frequency energy in the signal, the more likely they were to report it as coming from the front. Conclusions: Hearing impairment was associated with a decrease in the accuracy of self-motion processing for both static and moving signals. Hearing aids may not always reproduce dynamic self-motion–related cues with sufficient fidelity to allow reliable front/back discrimination.

Abstract The increasing prevalence of dementia in older adults warrants attention to the identification of practices that can delay or reduce likelihood of progression to early forms of cognitive impairment, in particular, to mild cognitive impairment (MCI) which is often considered a transitional stage between healthy aging and dementia. In this study, we investigated the effect of hearing impairment and hearing aid usage on cognitive decline and progression to MCI in cognitively healthy individuals. We used data from a large referral-based cohort obtained from the National Alzheimer’s Coordinating Center. The baseline sample included 5721 cognitively normal subjects aged ≥ 40. We found that hearing impairment was associated with increased risk of progression to MCI (hazard ratio [HR] = 1.40, 95%CI, 1.16-1.68, false discovery rate [FDR] P < 0.001) and an accelerated rate of cognitive decline (P < 0.001). Among hearing-impaired participants, hearing aid users were less likely to develop MCI (HR, 0.33; 95% CI, 0.23-0.47; FDR P < 0.001) and experienced slower cognitive decline (P = 0.004) when compared to those not using hearing aids. We found no statistically significant differences in risk of conversion to MCI between individuals with normal hearing and hearing-impaired adults using hearing aids (HR, 1.23; 95% CI, 0.99-1.50; FDR P = 0.08). Our findings highlight the need for a randomized clinical trial that will allow us to investigate whether there is a causal relationship between hearing loss, hearing aid use, and conversion to MCI. Such knowledge could provide new and novel insights into prevention of cognitive impairment and dementia.

Abstract Background: Hearing is one of the basic means of perception and communication, which is closely related with quality of life. However, hearing impairment is often unrecognized and undertreated, and impaired hearing may lead to greater burden of diseases as well as risk of hospitalization. To gain further insight into the association between hearing and hospitalization, we examined the shape and magnitude of hearing status gradients in the risk of hospitalization among Chinese middle-aged and older adults. Methods: We obtained data from a retrospective survey of the China Health and Retirement Longitudinal Study (CHARLS) conducted in 2011, 2013 and 2015, including 11,721 participants aged 45 years old and above with no hospitalization in 2011 baseline. Hospitalization variables included time to incident (first) hospitalization, annual number of hospitalizations and duration of last-time hospitalization. Cox proportional hazards models, negative binomial models and lognormal regression were fitted to examine the relationship between self-rated hearing status gradients and risk of hospitalization. Results: Of the total 11,721 participants, 54.46% reported having fair or poor hearing and 20.94% experienced at least one hospitalization during the study period. Older adults were exposed to higher risk of hospitalization than the middle-aged adults. For older adults, compared with excellent or very good hearing people, those with good, fair and poor hearing experienced a shorter time to incident (first) hospitalization, a greater annual number of hospitalizations and a longer last-time duration of hospitalization with the deterioration of hearing. However, there was no significant association for the middle-aged adults. Conclusions: We found a gradient decrease in time to first hospitalization, an increase in annual number of hospitalizations and duration of last-time hospitalization with the deterioration of hearing status in older adults. Actions should be taken to prevent and treat their hearing impairment, so as to decrease risk of hospitalization and improve their life quality.

Aim/Background: Individuals deprived of full hearing ability suffer from many problems in their social, professional, and personal lives. Prolonged hearing deprivation, particularly in children, results in many consequences including loss of control of one’s voice. Impaired hearing control of the voice leads to dysphonia of different degrees. The aim of this study was to analyse acoustic voice parameters in hearing-impaired, school-aged children (7–12 years) and the influence of treatment type on voice quality. Material and method: The subjects in this study were a group of 83 Polish school children, aged 7–12 years. ENT and phoniatric examination were performed on each subject prior to inclusion. Acoustic voice analysis was performed for each individual. The linguistic material was a prolonged [a] vowel. The acoustic analysis was performed with a digital spectrograph KAY 4300B for multidimensional voice analysis MDVP (Multi-Dimensional Voice Profile). The criterion to include patients in the study group was a profound prelingual, sensorineural hypoacusis. Within the study group, four subgroups were categorised according to the use of hearing devices: 20 children without any type of hearing device (HL), 20 children with hearing aids (HA), and 20 children with cochlear implants (CI). The children using hearing aids and cochlear implants were included in the study 6 months after the hearing rehabilitation was implemented. The control group (NH) consisted of 23 normal-hearing children, in the same age group, without any co-existing voice disorders. The statistical level of significance p < 0.05 was used. Results: The selected, clinically significant voice parameters were analysed for the groups of children in the study.
