ABSTRACT Introduction Previous studies have investigated listening effort in tinnitus patients compared to healthy individuals. These reported similar pure tone hearing thresholds between groups but did not investigate possible peripheral auditory dysfunction, which could affect the central system and increase even when are within normal range. This study aimed presence of by controlling for function (PAF). Methods included 16 chronic 23 matched controls, both with thresholds. The subjects were assessed using 0.125–20 kHz pure‐tone audiometry, a visual analogue scale (VAS), Montreal Cognitive Assessment (MoCA), Tinnitus Handicap Inventory (THI), matrix test, brainstem response (ABR), electroencephalography (EEG). EEG alpha band activity was recorded from parietal electrodes (P3, P4, P z ). Results power during encoding phase sentence presentation less than that control group. We found higher VAS scores participants. find significant differences test scores, ABR amplitude, or absolute latency values groups. change THI show correlation. Conclusion To best our knowledge, this is first controls while PAF. may expend more listening‐related despite having PAF

The drivers' distraction plays a crucial role in road safety as it is one of the main impacting causes accidents. phenomenon encompasses both psychological and environmental factors and, therefore, addressing complex interplay contributing to human automotive for developing technologies interventions improving safety. In scientific literature, different works were proposed characterization automotive, but there still lack univocal measure assess degree distraction, nor gold-standard tool that allows "detect" eventual events, traffic, additional driving tasks might contribute distraction. Therefore, present study aimed at an EEG-based "Distraction index" obtained by combination driver's mental workload attention neurometrics investigating validating its reliability analyzing together subjective behavioral measures. A total 25 licensed drivers involved this study, where they had drive two scenarios, i.e., City Highway, while secondary alternatively addition modulate attentional demand. statistical analysis demonstrated index identifying when along roads traffic conditions (all

Despite the proven effectiveness of cochlear implant (CI) in hearing restoration deaf or hard-of-hearing (DHH) children, to date, extreme variability verbal working memory (VWM) abilities is observed both unilateral and bilateral CI user children (CIs). Although clinical experience has long deficits this fundamental executive function CIs, cause date still unknown. Here, we have set out investigate differences brain functioning regarding impact monaural binaural listening CIs compared with normal (NH) peers during a three-level difficulty n-back task undertaken two sensory modalities (auditory visual).

The aim current study was to investigate acuity physiological responses and subjective acquired during different levels demand, relationship between these A total 125 participants (37 males 88 females, age range 37-72 years, pure-tone average thresholds at best ear -5.0 68.8 dB HL asymmetry ears 0.0 87.5 dB) completed a task. speech reception threshold (SRT) test with target sentences spoken by female voice masked male speech. Listening demand manipulated using three intelligibility: 20% correct recognition, 50%, 80% (IL20%, IL50%, IL80%, respectively). During task, peak pupil dilation (PPD), heart rate (HR), pre-ejection period (PEP), respiratory sinus arrhythmia (RSA), skin conductance level (SCL) were measured. For each condition, ratings performance, difficulty, tendency give up also collected.

Background: Despite substantial progress in investigating its psychophysical complexity, tinnitus remains a scientific and clinical enigma. The present study, through an ecological multidisciplinary approach, aims to identify associations between electroencephalographic (EEG) psycho-audiological variables. Methods: EEG beta activity, often related stress anxiety, was acquired from 12 patients (TIN group) 7 controls (CONT during audio cognitive task at rest. We also investigated psychological (SCL-90-R; STAI-Y; BFI-10) audiological (THI; TQ12-I; Hyperacusis) variables using non-parametric statistics assess differences relationships within groups. Results: In the TIN group, frontal activity positively correlated with hyperacusis, parietal trait anxiety; latter is associated depression CONT. Significant paranoid ideation openness were found Conclusions: connection anxiety trait, fronto-parietal cortices hyperacusis provides insights into brain functioning patients, offering quantitative descriptions for clinicians new treatment hypotheses.
