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.

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.

Objectives This study investigates the hypothesis that hearing aid amplification reduces effort within conversation for both hearing aid wearers and their communication partners. Levels of effort, in the form of speech production modifications, required to maintain successful spoken communication in a range of acoustic environments are compared to earlier reported results measured in unaided conversation conditions. Design Fifteen young adult normal-hearing participants and 15 older adult hearing-impaired participants were tested in pairs. Each pair consisted of one young normal-hearing participant and one older hearing-impaired participant. Hearing-impaired participants received directional hearing aid amplification, according to their audiogram, via a master hearing aid with gain provided according to the NAL-NL2 fitting formula. Pairs of participants were required to take part in naturalistic conversations through the use of a referential communication task. Each pair took part in five conversations, each of 5-min duration. During each conversation, participants were exposed to one of five different realistic acoustic environments presented through highly open headphones. The ordering of acoustic environments across experimental blocks was pseudorandomized. Resulting recordings of conversational speech were analyzed to determine the magnitude of speech modifications, in terms of vocal level and spectrum, produced by normal-hearing talkers as a function of both acoustic environment and the degree of high-frequency average hearing impairment of their conversation partner. Results The magnitude of spectral modifications of speech produced by normal-hearing talkers during conversations with aided hearing-impaired interlocutors was smaller than the speech modifications observed during conversations between the same pairs of participants in the absence of hearing aid amplification. Conclusions The provision of hearing aid amplification reduces the effort required to maintain communication in adverse conditions. This reduction in effort provides benefit to hearing-impaired individuals and also to the conversation partners of hearing-impaired individuals. By considering the impact of amplification on both sides of dyadic conversations, this approach contributes to an increased understanding of the likely impact of hearing impairment on everyday communication.

Hearing impaired persons are required to drive with hearing aids to supplement their hearing ability, however, there has not been sufficient discussion regarding the impact of the use of a hearing aid on driving a vehicle. In order to investigate the actual usage and driving conditions of using hearing aids while driving a vehicle, this paper uses a questionnaire to survey (1) how easy it is to drive when wearing hearing aids, and (2) how often hearing aids are not worn while driving. Concerning the ease of driving when wearing a hearing aid, it was suggested that people with congenital hearing loss were more likely to rely on visual information, and those with acquired hearing loss continue to use their experience of hearing. When the level of disability is high, it is difficult to drive when using the hearing aid, and when the disability level is low, it is easier to drive. Regarding the frequency of driving without wearing hearing aids, about 60 % of respondents had such an experience. Those who often drive without hearing aids had experienced headaches due to noise from wearing hearing aids compared to those who wear hearing aids at all times. Hearing aids are necessary assistive devices for hearing impaired persons to obtain hearing information, and to provide a safe driving environment. Therefore, this paper addresses issues to maintain a comfortable driving environment while wearing a hearing aid.

ABSTRACTThis paper presents the preliminary findings of a study examining the impact of congenital visual impairment on the development of motor skills and kinaesthetic acuity. Studies of children with a visual impairment have consistently noted deficits in motor development. It was hypothesised that these deficits may be linked with poor kinaesthetic sensitivity. Six preschool children with a visual impairment (mean age 55.17 months) were compared to nine classmates (mean age 56.67 months) matched for age, gender, and general verbal ability, on modified tasks from the Movement Assessment Battery for Children (M-ABC) and the Kinaesthetic Acuity Test (KAT). Although the difference between groups was significant for one task only (static balance), it was noted that all differences observed were in the hypothesised direction. Further longitudinal or cross-sectional data are required to provide a more comprehensive analysis of the relationship between vision impairment, kinaesthetic development, and motor skills.

The Impact

The regular use of hearing aids (more than 8 hours a day) benefits people in hearing for bettercommunication than those who are less-likely to use hearing aids Objective: The objective of thestudy was to assess the impact of hearing aids on the quality of life of hearing impaired individualsMethods: In this cross-sectional study total 50 participants were recruited by convenient samplingtechnique from Lahore, Pakistan. 50 patients who were diagnosed with hearing loss and wererecommended with hearing aids of both genders were included in the study. The International OutcomeInventory for Hearing Aids (IOI-HA), questionnaire was used for data collection. Data were analyzedthrough Statistical Package for Social Sciences (SPSS) version 23.0 Results: In this research 50hearing impaired individuals who were hearing aid users, participated. The mean age of participants was64.10+15.88 years. Among which 25 (50%) were males and 25(50%) were females. The average time ofhearing aid use was 3.88 hours, majority of patients responded that hearing aid helped quite a lot in thedaily routine (mean score of IOI-HA, 3.62), have moderate difficulty in residual activity (mean score of IOIHA,3.26), moderately satisfied with their hearing aid (mean score of IOI-HA, 3.28), moderately affect theparticipation restriction (mean score of IOI-HA, 3.20), impact of their hearing loss bothered moderately(mean score of IOI-HA, 3.14) and quality of life (QOL) was very much better (3.90). There was insignificantassociation between the QOL of males and females (p-value>0.05) Conclusions: It was concluded fromthe study that the hearing aids have a greater impact on the quality of life and socio-economic aspectsof hearing impaired individuals. Hearing loss is such a problem, which separates certain community ofhearing impaired individuals from the normal population. Individuals with hearing impairment not onlyhave to face personal communication problems but also it affects their health, independency and qualityof life in their daily routine.

Impaired Individual

According to the National Institute on Deafness and Other Communication Disorders1 approximately 37.5 million American adults aged eighteen and over report some trouble hearing. Despite the number of people affected by hearing impairment, the hard of hearing and deaf population are underrepresented. The hearing-impaired community faces a myriad of challenges in their daily lives communicating and relating to others. Unfortunately, there is a lack of resources for the hard of hearing and deaf population in schools, and a lack of affordability for hearing aids in the healthcare field. In this critical autoethnography, the author focuses on her experiences of coping with and navigating her world as a hearing-impaired individual. The autoethnographic account explores the author’s face-to-face encounters with her peers, audiologist, medical practitioners, and personal relationships centering her research on the communication barriers that often come with hearing loss including adjustments to sound, relating to others, and overcoming obstacles due to the lack of resources. The stories shared aim to illustrate how those with hearing impairments are disempowered in a world that is geared toward the hearing abled.

Consonant Voicing

Background: A possible voicing cue used to differentiate voiced and voiceless cognate pairs is envelope onset asynchrony (EOA). EOA is the time between the onsets of two frequency bands of energy (in this study one band was high-pass filtered at 3000 Hz, the other low-pass filtered at 350 Hz). This study assessed the perceptual impact of manipulating EOA on voicing perception of initial stop consonants, and whether normal-hearing and hearing-impaired listeners were sensitive to changes in EOA as a cue for voicing. Purpose: The purpose of this study was to examine the effect of spectrally asynchronous auditory delay on the perception of voicing associated with initial stop consonants by normal-hearing and hearing-impaired listeners. Research Design: Prospective experimental study comparing the perceptual differences of manipulating the EOA cues for two groups of listeners. Study Sample: Thirty adults between the ages of 21 and 60 yr completed the study: 17 listeners with normal hearing and 13 listeners with mild-moderate sensorineural hearing loss. Data Collection and Analysis: The participants listened to voiced and voiceless stop consonants within a consonant-vowel syllable structure. The EOA of each syllable was varied along a continuum, and identification and discrimination tasks were used to determine if the EOA manipulation resulted in categorical shifts in voicing perception. In the identification task the participants identified the consonants as belonging to one of two categories (voiced or voiceless cognate). They also completed a same-different discrimination task with the same set of stimuli. Categorical perception was confirmed with a d-prime sensitivity measure by examining how accurately the results from the identification task predicted the discrimination results. The influence of EOA manipulations on the perception of voicing was determined from shifts in the identification functions and discrimination peaks along the EOA continuum. The two participant groups were compared in order to determine the impact of EOA on voicing perception as a function of syllable and hearing status. Results: Both groups of listeners demonstrated a categorical shift in voicing perception with manipulation of EOA for some of the syllables used in this study. That is, as the temporal onset asynchrony between low- and high-frequency bands of speech was manipulated, the listeners' perception of consonant voicing changed between voiced and voiceless categories. No significant differences were found between listeners with normal hearing and listeners with hearing loss as a result of the EOA manipulation. Conclusions: The results of this study suggested that both normal-hearing and hearing-impaired listeners likely use spectrally asynchronous delays found in natural speech as a cue for voicing distinctions. While delays in modern hearing aids are less than those used in this study, possible implications are that additional asynchronous delays from digital signal processing or open-fitting amplification schemes might cause listeners with hearing loss to misperceive voicing cues.

An extensive psychoeducational evaluation was administered to 40 hearing-impaired children to investigate the effects of degree of hearing impairment, age, and other factors on intellectual, social, academic, and language behavior. Although children varied greatly in performance, hearing loss of any degree appeared to affect psychoeducational development adversely, leading to the conclusion that even minimal hearing loss places children at risk for language and learning problems.

The Impact

The inclusive education method has substantial contributions to hearing-impaired individuals’ education and socialization. However, the poor physical environment and acoustic comfort conditions negatively affect speech intelligibility at such places and therefore, the quality of education. Upon determining that there are very few subjective evaluation studies, we conducted a study regarding the impact of acoustic comfort conditions on speech intelligibility at inclusive education places. Within the scope of the study, first, a classroom was determined, and the current acoustic conditions of the class were evaluated objectively by field acoustic measurements. A calibrated model was created in the simulation software of the relevant class and then two more models with optimum reverberation time values of 0.4 s and 0.8 s as suggested in the literature, and auralizations were performed for the models. For subjective evaluation, a subject group of hearing-impaired and normal hearing individuals fulfilling equal conditions were tested by speech discrimination test in real-time in the classroom and from auralization recordings in a laboratory setting. Regarding the results obtained, it was observed that speech intelligibility percentage of normal hearing individuals increased as expected while in hearing-impaired individuals, contrary to the expectations, percentage differed from one another, and there was no increase. Following the discussions with experts, it was concluded that different hearing aids used by hearing-impaired individuals might lead to this situation. Accordingly, it occurs that the possibility to achieve a good speech intelligibility for hearing-impaired individuals even if optimum acoustic values suggested are fulfilled in education places remains unclear.
