Purpose: Subjective ratings of listening effort might be applicable to estimate hearing difficulties at positive signal-to-noise ratios (SNRs) at which speech intelligibility scores are near 100%. Hence, ratings of listening effort were compared with speech intelligibility scores at different SNRs, and the benefit of hearing aids was evaluated. Method: Two groups of listeners, 1 with normal hearing and 1 with hearing impairment, performed adaptive speech intelligibility and adaptive listening effort tests (Adaptive Categorical Listening Effort Scaling; Krueger, Schulte, Brand, & Holube, 2017) with sentences of the Oldenburg Sentence Test (Wagener, Brand, & Kollmeier, 1999a, 1999b; Wagener, Kühnel, & Kollmeier, 1999) in 4 different maskers...

Purpose: This study examined the relationship between working memory (WM) and speech comprehension in older adults with hearing impairment (HI). It was hypothesized that WM would explain significant variance in speech comprehension measured in multitalker babble (MTB). Method: Twenty-four older (59-73 years) adults with sensorineural HI participated. WM capacity (WMC) was measured using 3 complex span tasks. Speech comprehension was assessed using multiple passages, and speech identification ability was measured using recall of sentence final-word and key words...

BACKGROUND: The use of cochlear implants has been a remarkable success in reducing disabilities in those with impaired hearing, which have made a significant change in the patients' quality of life. Only by relying on cochlear implants, disabilities cannot be eliminated in the hearing impaired, and, alongside this intervention, rehabilitation practices such as through family and community support are necessary. AIM: To explain the needs of parents of children with cochlear implants to increase the quality of rehabilitation services and family-based interventions...

In alpine regions, cows are often equipped with bells during pasture season to ensure that farmers can locate them. Constant exposure to the chime of a bell may affect cows' acoustic perception in general. The aim of this study is to test whether routine bell exposure affects the reactivity to a noise stimulus and might be associated with hearing impairment in cows. For the assessment, behavioral and cardiac indicators were used as indirect measures of hearing capacity. Cows that were either used to wearing a bell or not were exposed to a playback of low and high amplitude (=varying loudness)...

BACKGROUND: Visual impairment (VI) and hearing impairment (HI) are the two most common types of sensory disability encountered clinically. However, VI and HI result in different limitations in daily life. We assessed the level of functioning in patients with VI or HI based on the International Classification of Functioning, Disability, and Health. METHODS: This nationwide, cross-sectional study included 312 people with VI and 540 people with HI. Each participant's degree of functioning and disability was evaluated using the World Health Organization Disability Assessment Schedule 2...

This study examines the relative risk for suicide attempts (SA) among high-school students self-identifying with one or more disability classifications (nine); assesses the extent to which youth with disabilities are disproportionately vulnerable to risk factors that predict suicidal behavior among all adolescents; and explores whether disability status adds to risk for SA after accounting for a comprehensive set of known risk and protective factors for SA. Analyses using Wisconsin's 2012 Dane County Youth Assessment Survey data found that youth in each disability category were 3-9 times more likely to report suicide attempt(s) relative to peers, and the endorsement of multiple disabilities tripled the risk SA relative to youth reporting a single disability...

The absence of functional outer hair cells is a component of several forms of hereditary hearing impairment, including Usher syndrome, the most common cause of concurrent hearing and vision loss. Antisense oligonucleotide (ASO) treatment of mice with the human Usher mutation, Ush1c c.216G>A, corrects gene expression and significantly improves hearing, as measured by auditory-evoked brainstem responses (ABRs), as well as inner and outer hair cell (IHC and OHC) bundle morphology. However, it is not clear whether the improvement in hearing achieved by ASO treatment involves the functional rescue of outer hair cells...

REVIEW
Lyndal Carter, Deborah Black
This study investigated the attitudes and behaviors of young adults with hearing impairment (HI), in relation to leisure noise. It was hypothesized that young people with HI would have more negative perceptions of noise exposure than their peers with nonimpaired (normal) hearing (NH) and would engage more frequently in self-protective behaviors. Questionnaires were administered as part of a larger study of young Australians with: (1) preadult onset HI and (2) NH. Data from adults (age range 18 to 24 years; n  = 79 with HI, n  = 131 with NH) were selected for the current analysis...

The developmental and physiological complexity of the auditory system is likely reflected in the underlying set of genes involved in auditory function. In humans, over 150 non-syndromic loci have been identified, and there are more than 400 human genetic syndromes with a hearing loss component. Over 100 non-syndromic hearing loss genes have been identified in mouse and human, but we remain ignorant of the full extent of the genetic landscape involved in auditory dysfunction. As part of the International Mouse Phenotyping Consortium, we undertook a hearing loss screen in a cohort of 3006 mouse knockout strains...

Emotions are commonly recognized by combining auditory and visual signals (i.e., vocal and facial expressions). Yet it is unknown whether the ability to link emotional signals across modalities depends on early experience with audio-visual stimuli. In the present study, we investigated the role of auditory experience at different stages of development for auditory, visual, and multisensory emotion recognition abilities in three groups of adolescent and adult cochlear implant (CI) users. CI users had a different deafness onset and were compared to three groups of age- and gender-matched hearing control participants...

Total laser energy in CO2 stapedotomy depends on the laser settings and the amount of applications. It is unclear if the amount of total laser energy affects bone-conduction hearing thresholds and if possible effects are temporary or permanent. Alterations of bone-conduction hearing thresholds after single or multiple-shot CO2 laser stapedotomy were analyzed between 1 and 3 weeks and 1.5-6 months after primary (n = 501) or revision surgeries (n = 153) and correlated to time, laser energy, frequency, surgical technique, and pathology encountered in revision stapedotomy...

In this invited review article I present a translational perspective and overview of our research on auditory hallucinations in schizophrenia at the University of Bergen, Norway with a focus on the neuronal mechanisms underlying the phenomenology of experiencing "hearing voices". An auditory verbal hallucination, i.e. "hearing a voice", is defined as a sensory experience in the absence of a corresponding external sensory source that could explain the phenomenological experience. I suggest a general frame or scheme for the study of auditory verbal hallucinations which is called Levels of Explanation (LoE)...

BACKGROUND: Recently it has been shown in animal studies that deep brain stimulation (DBS) of auditory structures was able to reduce tinnitus-like behavior. However, the question arises whether hearing might be impaired when interfering in auditory-related network loops with DBS. METHODS: The auditory brainstem response (ABR) was measured in rats during high frequency stimulation (HFS) and low frequency stimulation (LFS) in the central nucleus of the inferior colliculus (CIC, n = 5) or dentate cerebellar nucleus (DCBN, n = 5)...

Light-gated ion channels and transporters have been applied to a broad array of excitable cells including neurons, cardiac myocytes, skeletal muscle cells and pancreatic β-cells in an organism to clarify their physiological and pathological roles. Nonetheless, among nonexcitable cells, only glial cells have been studied in vivo by this approach. Here, by optogenetic stimulation of a different nonexcitable cell type in the cochlea of the inner ear, we induce and control hearing loss. To our knowledge, deafness animal models using optogenetics have not yet been established...

Background: Mutations leading to changes in properties, regulation, or expression of connexin-made channels have been implicated in 28 distinct human hereditary diseases. Eight of these result from variants of connexin 26 (Cx26), a protein critically involved in cell-cell signaling in the inner ear and skin. Lack of non-toxic drugs with defined mechanisms of action poses a serious obstacle to therapeutic interventions for diseases caused by mutant connexins. In particular, molecules that specifically modulate connexin hemichannel function without affecting gap junction channels are considered of primary importance for the study of connexin hemichannel role in physiological as well as pathological conditions...
