Hard of hearing

Raphael Koning, Ian C Bruce, Sam Denys, Jan Wouters
State-of-the-art hearing aids (HAs) try to overcome the deficit of poor speech intelligibility (SI) in noisy listening environments using digital noise reduction (NR) techniques. The application of time-frequency masks to the noisy sound input is a common NR technique to increase SI. The binary mask with its binary weights and the Wiener filter with continuous weights are representatives of a hard- and a soft-decision approach for time-frequency masking. In normal-hearing listeners, the ideal Wiener filter (IWF) outperforms the ideal binary mask (IBM) in terms of SI and speech quality with perfect SI even at very low signal-to-noise ratios...

This manuscript reviews 28 studies of reading research on deaf and hard-of-hearing (DHH) students published since 2000 that used correlational analyses. The examination focused on assessment issues affecting measurement and analysis of relationships between early phonological or orthographic skills and reading comprehension. Mixed outcomes complicate efforts to determine evidence-based practices, and to develop an accurate model of reading. Across the 28 studies, DHH participants represented a wide age range with potential floor and ceiling effects that reduce score variability for valid correlations...

Cochlear implantation in children with deaf or severely hearing-impaired parents is possible. It is necessary to organize intensive auditory-verbal training before the children undergo implantation. Success of the children depends on mediators supporting the parents. These children grow up bilingually: sign language and spoken language. They can attend schools for the hard-of-hearing or regular schools for the hearing.

The study explored the social capital of Australian adolescents who were deaf or hard of hearing (DHH) and their parents, and investigated the relationship between social capital and individual characteristics, language, literacy, and psychosocial outcomes. Sixteen adolescents (ages 11-14 years) and 24 parents enrolled in the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study completed an online questionnaire on social capital and psychosocial outcomes. Information about demographics, language, and literacy was retrieved from the LOCHI study database...

Speech intelligibility is currently measured by scoring how well a person can identify a speech signal. The results of such behavioral measures reflect neural processing of the speech signal, but are also influenced by language processing, motivation, and memory. Very often, electrophysiological measures of hearing give insight in the neural processing of sound. However, in most methods, non-speech stimuli are used, making it hard to relate the results to behavioral measures of speech intelligibility. The use of natural running speech as a stimulus in electrophysiological measures of hearing is a paradigm shift which allows to bridge the gap between behavioral and electrophysiological measures...

BACKGROUND: Within the field of behavioral health research, one of the most understudied populations is the U.S. Deaf and hard-of-hearing (D/HH) population - a diverse group of individuals with hearing loss that have varied language and communication preferences, community affiliations, and sociocultural norms. Recent research identified concerning behavioral health disparities experienced by the D/HH population; yet, little research has been conducted to extend these findings to the topic of substance use disorder...

Introduction The use of telepractice, a method of delivering services through telecommunications technologies that provides two-way, synchronous audio and video signals in real-time, is becoming increasingly commonplace in early childhood education and intervention for children who are deaf or hard of hearing. Although the use of telepractice has been validated in the health sector as a viable and effective alternative to in-person service provision, evidence to support its use in the delivery of family-centred early intervention is still emerging...

The emergence of positive psychology as an approach to studying what makes life worth living has inspired a new wave of research. Studies have focused on the prevalence and degree of positive attributes, attitudes, and characteristics in the wider population. Increasingly, lessons learned from positive psychology have been applied to understanding the more diverse experiences of individuals belonging to various groups. Only recently, however, has positive psychology research incorporated a disability perspective, and very little research from a positive psychology stance has been conducted with deaf people...

The estimated incidence of sensorineural hearing impairment (>40 dB HL) at birth is 1.86 per 1000 newborns in developed countries and 30-40% of these are unilateral. Profound sensorineural unilateral hearing impairment or single sided deafness (SSD) can be treated with a cochlear implant. However, this treatment is costly and invasive and unnecessary in the eyes of many. Very young children with SSD often do not exhibit language and cognitive delays and it is hard to imagine that neurocognitive skills will present difficulties with one good ear...

There has been considerable variability within the literature concerning the extent to which deaf/hard of hearing individuals are able to process phonological codes during reading. Two experiments are reported in which participants' eye movements were recorded as they read sentences containing correctly spelled words (e.g., church), pseudohomophones (e.g., cherch), and spelling controls (e.g., charch). We examined both foveal processing and parafoveal pre-processing of phonology for three participant groups-teenagers with permanent childhood hearing loss (PCHL), chronological age-matched controls, and reading age-matched controls...

BACKGROUND: Clear cell carcinoma in scars after cesarean section is extremely rare, with only 22 cases reported in the literature. Management of this condition needs to be further explored. Here, we report of a patient with clear cell carcinoma of the abdominal wall that developed 35 years after cesarean section. CASE REPORT: The material of the study was a group of 61 patients divided into two groups. Group I - 35 deaf or with profound sensorineural hearing loss children (the pupils of the deaf and hard of hearing school), aged 5-17 years (average 9,2 years), 14 males, 21 females, II - control group comprised 26 normal hearing patients, aged 5-16 years (average 10,4 years), 14 males, 12 females (patients of Department of Pediatric Otolaryngology, Audiology and Phoniatrics, Medical University of Lodz)...

Research on the unique experiences of deaf people is rare, and limited information exists regarding the nature and extent of violence against this population. Existing scholarship highlights the increased vulnerabilities of deaf individuals; however, there remains a paucity of research that examines how deaf and hard of hearing individuals perceive their own victimization. Also lacking is research on the experiences of deaf individuals outside of the United States, where cultural norms and the status of the deaf may be quite different...

Academic English is an essential literacy skill area for success in post-secondary education and in many work environments. Despite its importance, academic English is understudied with deaf and hard of hearing (DHH) students. Nascent research in this area suggests that academic English, alongside American Sign Language (ASL) fluency, may play an important role in the reading proficiency of DHH students in middle and high school. The current study expands this research to investigate academic English by examining student proficiency with a sub-skill of academic writing called superordinate precision, the taxonomical categorization of a term...

Purpose: This study investigates false belief (FB) understanding in children who are hard of hearing (CHH) compared with children with normal hearing (CNH) at ages 5 and 6 years and at 2nd grade. Research with this population has theoretical significance, given that the early auditory-linguistic experiences of CHH are less restricted compared with children who are deaf but not as complete as those of CNH. Method: Participants included CHH and CNH who had completed FB tasks as part of a larger multicenter, longitudinal study on outcomes of children with mild-to-severe hearing loss...

BACKGROUND: The current recommended therapies for bacterial meningitis are effective antimicrobial agents and the implementation of childhood vaccination programs. However, the role of adjunctive dexamethasone therapy in bacterial meningitis remains controversial. METHODS: Using meta-analysis, this study aims to investigate the efficacy of adjunctive dexamethasone therapy in bacterial meningitis by comparing it with antibiotic therapy. Documents of randomized controlled trials (RCT) related to the treatment of bacterial meningitis in children with dexamethasone published since the establishment of the databases to December in 2016 were retrieved from the databases of Cochrane Library, Pubmed, MEDLINE, EMBASE, Chinese BioMedical Literature Database, and China National Knowledge Infrastructure...

To preserve residual hearing, techniques for monitoring and reducing the effects of trauma during cochlear implant surgery are being developed. This study examines the relationships between intraoperative recordings (electrode insertion force and electrocochleography), trauma, and hearing loss after cochlear implantation. The study also evaluated the efficacy of intravenous steroids for reducing hearing loss after implantation. Thirty-two normal-hearing guinea pigs were randomly implanted with electrode arrays of differing stiffness ('hard' or 'soft')...
