Binaural Speech Understanding With Bilateral Cochlear Implants in Reverberation.

Conclusions: The magnitude of 4 different binaural advantages was measured on the same group of bilateral CI subjects fitted with clinical processors in 2 different reverberation conditions. The results of this work demonstrate the impeding properties of reverberation on binaural speech understanding. In addition, results indicate that CI recipients who struggle in everyday listening environments are also more likely to benefit less in highly reverberant environments from their bilateral processors.

Cochlear implants (CIs) are surgically implanted devices for treating severe-to-profound hearing loss (National Institute on Deafness and Other Communication Disorders, 2011). A CI uses an electrode array implanted within the cochlea to stimulate the spiral ganglion (SG) nerves to induce the sensation of hearing. The SG nerves are tonotopically ordered by decreasing characteristic frequency along the length of the cochlea (Greenwood, 1990; Stakhovskaya et al., 2007) (Shown in Figure 1). A SG nerve is stimulated when the frequency associated with it exists in the incoming sound (Wilson and Dorman, 2008).

This study examines the correlates of happiness among 377 deaf adults using an anonymous online questionnaire. Results indicate that there are several correlates of happiness, including satisfaction with family and friends ’ relationships and communication, membership in the deaf and hearing communities, education, income, body image, education, and resilience. All except education were predictors of happiness scores. These findings are supported by other studies of the general population. They support the idea that deaf individuals are happy when they have satisfying employment, living conditions, family and friends...

This study aimed to explore the molecular mechanism of 25-OHC regulating the expression of OSBPL2. Using dual-luciferase reporter assay, we found a decrease of nuclear transcription factor Y subunit alpha (NFYA) bound with OSBPL2 promoter when HeLa cells were treated with by 25-OHC. Furthermore, transcriptome sequencing and RNA interference results revealed that the p53/sterol regulatory element binding transcription factor 2 (SREBF2) signaling pathway was involved in the NFYA-dependent transcription of OSBPL2 induced by 25-OHC. Based on these results, we concluded that pleomorphic adenoma gene 1 (PLAG1) and NFYA participa...

Abstract Cochlear implant (CI) users do not reliably associate an increase in pulse rate above 300 pulses per second (pps) with an increase in pitch. The locus of this upper limit of pitch remains unknown. The present study tested the hypothesis that this deficit resides at least initially at the auditory nerve. The hypothesis was tested by comparing pulse rate discrimination in different neural excitation patterns, in which a large versus small population of auditory nerve fibers was activated. If poorer pulse rate discrimination was found under conditions where narrower spread of neural excitation (SOE) was anti...

Abstract Bilingual individuals automatically translate written words from one language to another. While this process is established in spoken-language bilinguals, there is less known about its occurrence in deaf bilinguals who know signed and spoken languages. Since sign language uses motion and space to convey linguistic content, it is possible that action simulation in the brain's sensorimotor system plays a role in this process. We recorded EEG from deaf participants fluent in ASL as they read individual English words and found significant differences in alpha and beta EEG at central electrode sites during the...

We report a Japanese family with HDR syndrome and congenital choanal atresia. The 6-year-old female proband was diagnosed with epilepsy at the age of three. Under carbamazepine monotherapy, the patient presented hypoparathyroidism accompanied by severe hypocalcemia. Subsequently, renal ultrasound analysis revealed bilateral multicystic dysplastic kidneys.

Defects in these proteins lead to deafness and vestibular areflexia in USH patients. Mutations in a non-USH protein, glutaredoxin domai...

Conclusions: Models of bone conduction devices that have intact skin cannot be measured with the skull simulator. This study is the first to present and evaluate a new tool for bone conduction verification. The surface microphone is capable of yielding equivalent audibility measurements as the skull simulator for percutaneous bone conduction users at multiple input levels. This device holds potential for measuring other bone conduction devices (Sentio, BoneBridge, Attract, Soft headband devices) that do not have a percutaneous implant.

CONCLUSION: Today, one can recognise that a scant evidence base and misconceptions influenced the mismanagement of hearing loss by otolaryngologists in World War I. However, noise-induced hearing loss is still very much a feature of armed conflict. PMID: 30370887 [PubMed - as supplied by publisher]
