There have been few reports that investigated the effects of the degree and pattern of a spectral smearing of stimuli due to deteriorated hearing ability on the performance of auditory brain-computer interface (BCI) systems. In this study, we assumed that such spectral smearing of stimuli may affect the performance of an auditory steady-state response (ASSR)-based BCI system and performed subjective experiments using 10 normal-hearing subjects to verify this assumption. We constructed smearing-reflected stimuli using an 8-channel vocoder with moderate and severe hearing loss setups and, using these stimuli, performed subjective concentration tests with three symmetric and six asymmetric smearing patterns while recording electroencephalogram signals...

BACKGROUND: Several case-control studies reported the relationship between single nucleotide polymorphisms (SNPs) in HSP70 genes and noise-induced hearing loss (NIHL). However, their conclusions are conflicting. This meta-analysis aims to identify the association of HSP70 variants and NIHL susceptibility. METHOD: A systematical literature search was performed in PubMed, Web of Science, EMBASE, and Wanfang Chinese database. The pooled odds radio (OR), 95% confidence interval (CI) and p value were calculated in fixed- or random-effects model according to the I2 value in the heterogeneity test...

Exposure to underwater sound can cause permanent hearing loss and other physiological effects in marine animals. To reduce this risk, naval sonars are sometimes gradually increased in intensity at the start of transmission ('ramp-up'). Here, we conducted experiments in which tagged humpback whales were approached with a ship to test whether a sonar operation preceded by ramp-up reduced three risk indicators - maximum sound pressure level (SPLmax), cumulative sound exposure level (SELcum) and minimum source-whale range (Rmin) - compared with a sonar operation not preceded by ramp-up...

Deafness, an issue that affects millions of people around the globe, is manifested in different intensities and related to many causes. This impairment negatively affects different aspects of the social life of the deaf people, and music-centered situations (concerts, religious events, etc.) are obviously not inviting for them. The Auris System was conceived to provide the musical experimentation for people who have some type of hearing loss. This system is able to extract musical information from audio and create a representation for music pieces using different stimuli, a new media format to be interpreted by other senses than the hearing...

: Auditory evoked potentials (AEP) are highly demanded during the whole process of equipping patients with cochlear implants (CI). They play an essential role in preoperative diagnostics, intraoperative testing, and postoperative monitoring of auditory performance and success. The versatility of AEP's is essentially enhanced by their property to be evokable by acoustic as well as electric stimuli. Thus, the electric responses of the auditory system following acoustic stimulation and recorded by the conventional surface technique as well as by transtympanic derivation from the promontory (Electrocochleography [ECochG]) are used for the quantitative determination of hearing loss and, additionally, electrically evoked compound actions potentials (ECAP) can be recorded with the intracochlear electrodes of the implant just adjacent to the stimulation electrode to check the functional integrity of the device and its coupling to the auditory system...

Elderly people often complain about poor speech understanding in noisy environments. In clinical practice, speech tests under noise conditions are used to examine hearing ability. The HÖRSTAT study, conducted on a population-based random sample consisting of 1903 adults, used the Goettingen Sentence Test (GÖSA) under noise conditions along with pure-tone audiometry. Hearing impairment was defined as pure-tone average at 0.5, 1, 2 and 4 kHz (PTA-4) greater than 25 dB HL in the better ear (WHO criterion). As expected, pure-tone thresholds and speech recognition thresholds (SRT) in GÖSA worsened steadily with age...

This study investigates the psychometric properties of the Polish version of the Tinnitus and Hearing Survey (THS-POL), which is a tool for evaluating what proportion of patients' tinnitus is due to hearing problems and what proportion is specifically due to the tinnitus. The THS-POL was created using the translation-backtranslation method. Study participants completed the THS-POL twice over a period of 3 days. The test-retest analysis shows excellent strength of correlations (THS-POL subscale A r = 0.89, subscale B r = 0...

REVIEW
Linda W Norrix, David Velenovsky
BACKGROUND: The auditory brainstem response (ABR) is used to estimate behavioral hearing thresholds in infants and difficult-to-test populations. Differences between the toneburst ABR and behavioral thresholds exist making the correspondence between the two measures less than perfect. Some authors have suggested that corrections be applied to ABR thresholds to account for these differences. However, because there is no agreed upon universal standard, confusion regarding the use of corrections exists...

BACKGROUND: Unilateral sensorineural hearing loss (USNHL) can have a negative impact on functions associated with the advantages of balanced, binaural hearing. Although single-sided deafness, which is a complete loss of audibility in one ear, has gained increased interest in the published research, there is a gap in the literature concerning hearing aid outcomes for individuals with residual, or otherwise "aidable," hearing in the affected ear. PURPOSE: To assess hearing aid outcomes for a group of individuals with USNHL with residual, aidable function...

BACKGROUND: Health behavior theories can provide an understanding of hearing health behaviors and, more importantly, can be used to develop theoretically based strategies to change these health behaviors. PURPOSE: To develop a theory-based brief intervention to increase help-seeking for adult hearing loss and to conduct a pilot study to evaluate its feasibility, effectiveness, and impact on hearing beliefs and behaviors. RESEARCH DESIGN: An intervention was designed that could be easily administered by a health-care provider who does not have expertise in audiology-such as a primary care physician, community nurse, or social worker...

Hearing loss, including genetic hearing loss, is one of the most common forms of sensory deficits in human with limited options of treatment. Adeno-associated virus (AAV)-mediated gene transfer has been shown to effectively recover auditory functions in mouse models of genetic deafness when delivered at neonatal stages. However, the mouse cochlea is still developing at those time points whereas in human the newborn inner ears are already fully mature. For effective gene therapy to treat genetic deafness, it is necessary to determine whether or not AAV-mediated therapy can be equally effective in the fully mature mouse inner ear without causing damages to the inner ear...

BACKGROUND: Cisplatin is one of the most ototoxic chemotherapy drugs, resulting in a permanent and irreversible hearing loss in up to 50% of patients. Cisplatin and gentamicin are thought to damage hearing through a common mechanism, involving reactive oxygen species in the inner ear. Aspirin has been shown to minimise gentamicin-induced ototoxicity. We, therefore, tested the hypothesis that aspirin could also reduce ototoxicity from cisplatin-based chemotherapy. METHODS: A total of 94 patients receiving cisplatin-based chemotherapy for multiple cancer types were recruited into a phase II, double-blind, placebo-controlled trial and randomised in a ratio of 1:1 to receive aspirin 975 mg tid and omeprazole 20 mg od, or matched placebos from the day before, to 2 days after, their cisplatin dose(s), for each treatment cycle...
