Hearing loss is the most common sensorineural disorder worldwide and is associated with more than 1000 mutations in more than 90 genes. While mutations in genes such as GJB2 (gap-junction protein β 2) and GJB6 (gap-junction protein β 6) are highly prevalent in Caucasian, Asian, and Middle Eastern populations, they are rare in both native African populations and those of African descent. The objective of this paper is to review the current knowledge regarding the epidemiology and genetics of hearing loss in African populations with a focus on native sub-Saharan African populations...

OBJECTIVE: Bilateral audiometric notch (BN) at 4000-6000 Hz was identified as a noise-induced hearing loss (NIHL) phenotype for genetic association analysis in college-aged musicians. This study analysed BN in a sample of US youth. DESIGN: Prevalence of the BN within the study sample was determined and logistic-regression analyses were performed to identify audiologic and other demographic factors associated with BN. Computer-simulated "flat" audiograms were used to estimate potential influence of false-positive rates in estimating the prevalence of the BN...

OBJECTIVE: Listening is at the very heart of communication in healthcare, but largely ignored in research and teaching. This paper presents different perspectives on listening within the context of healthcare and its implications for goal-directed communication. METHODS: The assets of listening are examined from several angles (the listening patient, the listening health professional, and the listening self) and illustrated by the results of relevant research. RESULTS: Listening is a multidimensional concept and serves different purposes in healthcare...

Previous research has reported effects of masker type and signal-to-noise ratio (SNR) on listening effort, as indicated by the peak pupil dilation (PPD) relative to baseline during speech recognition. At about 50% correct sentence recognition performance, increasing SNRs generally results in declining PPDs, indicating reduced effort. However, the decline in PPD over SNRs has been observed to be less pronounced for hearing-impaired (HI) compared to normal-hearing (NH) listeners. The presence of a competing talker during speech recognition generally resulted in larger PPDs as compared to the presence of a fluctuating or stationary background noise...

BACKGROUND: Children with unilateral cochlear implants (CIs) may have delayed vocabulary development for an extended period after implantation. Bilateral cochlear implantation is reported to be associated with improved sound localization and enhanced speech perception in noise. This study proposed that bilateral implantation might also promote early vocabulary development. Knowledge regarding vocabulary growth and composition in children with bilateral CIs and factors associated with it may lead to improvements in the content of early speech and language intervention and family counselling...

Children who are deaf and receive bilateral cochlear implants (BiCIs) perform better on spatial hearing tasks using bilateral rather than unilateral inputs; however, they underperform relative to normal-hearing (NH) peers. This gap in performance is multi-factorial, including the inability of speech processors to reliably deliver binaural cues. Although much is known regarding binaural sensitivity of adults with BiCIs, less is known about how the development of binaural sensitivity in children with BiCIs compared to NH children...

Behavioral health needs in justice-involved adolescents are an increasing concern, as it has been estimated that two-thirds of youths in the juvenile justice system now meet the criteria for one or more psychological disorders. This article describes the application of the Sequential Intercept Model (SIM), developed to describe five "points of interception" from standard prosecution into rehabilitation-oriented alternatives for adults (Munetz & Griffin, 2006), to juvenile justice. The five SIM intercepts are: (1) first contact with law enforcement or emergency services; (2) initial hearings and detention following arrest; (3) jails and courts (including problem-solving courts); (4) re-entry from jails, prisons and forensic hospitals; and (5) community corrections and community support, including probation and parole...

Importance: Older adults with limited life expectancy are frequently screened for cancer even though it exposes them to risks of screening with minimal benefit. Patient preferences may be an important contributor to continued screening. Objective: To examine older adults' views on the decision to stop cancer screening when life expectancy is limited and to identify older adults' preferences for how clinicians should communicate recommendations to cease cancer screening...

Animals are frequently used for the development and testing of new hearing devices. Dimensions of the middle ear and cochlea differ significantly between humans and commonly used animals, such as rodents or cats. The sheep cochlea is anatomically more like the human cochlea in size and number of turns. This study investigated the middle-ear ossicular velocities and intracochlear sound pressure (ICSP) in sheep temporal bones, with the aim of characterizing the sheep as an experimental model for implantable hearing devices...

INTRODUCTION: In the UK, it is estimated that a disabling hearing loss (HL) affects 1 in 6 people. HL has functional, economic and social-emotional consequences for affected individuals. Intervention for HL focuses on improving access to the auditory signal using hearing aids or cochlear implants. However, even if sounds are audible and speech is understood, individuals with HL often report increased effort when listening.Listening effort (LE) may be measured using self-reported measures such as patient-reported outcome measures (PROMs)...

BACKGROUND: Innovations in hearing aid technology influence clinicians and individuals who use hearing aids. Little research, to date, explains the innovation adoption experiences and perspectives of clinicians and patients, which matter to a field like audiology, wherein technology innovation is constant. By understanding clinician and patient experiences with such innovations, the field of audiology may develop technologies and ways of practicing in a manner more responsive to patients' needs, and attentive to society's influence...

BACKGROUND: Previous studies have suggested elevated reflex thresholds in children with auditory processing disorders (APDs). However, some aspects of the child's ear such as ear canal volume and static compliance of the middle ear could possibly affect the measurements of reflex thresholds and thus impact its interpretation. Sound levels used to elicit reflexes in a child's ear may be higher than predicted by calibration in a standard 2-cc coupler, and lower static compliance could make visualization of very small changes in impedance at threshold difficult...
