Background While there is no cure for tinnitus, research has shown that cognitive behavioral therapy (CBT) effective in managing clinical sequelae. Although traditional CBT labor-intensive and costly, new online consultations may improve accessibility. Moreover, promise an engaging conversational agent, or a “chatbot,” delivering conversation-like manner allowing users to work through complex situations with the guidance of virtual coach. Currently, little examining possible hybrid model...
This study examined (1) the utility of a clinical system to record acoustic change complex (ACC, an event-related potential recorded by electroencephalography) for assessing speech discrimination in infants, and (2) relationship between ACC functional performance real life. Participants included 115 infants (43 normal-hearing, 72 hearing-impaired), aged 3–12 months. ACCs were using [szs], [uiu], spectral rippled noise high-pass filtered at 2 kHz as stimuli. Assessments conducted age 3–6...
This article brings together the work we have been doing at National Acoustic Laboratories (NAL) to make cortical threshold testing easy, fast, and accurate. Our aim is improve techniques for estimating hearing thresholds on people who, whatever reason, are unable give reliable behavioural responses indicate that they heard a sound. The particular described general applicability testing, evaluated within practical package will become part of HEARLab family test modules. Cortical nicely...
To determine the influence of auditory stimuli spectral characteristics on cortical evoked potentials (CAEPs).CAEPs were obtained from 15 normal-hearing adults in response to six multitone (MT), four pure-tone (PT), and two narrowband noise stimuli. The sounds presented at 10, 20, 40 dB above threshold, which estimated behaviorally beforehand. root mean square amplitude CAEP detectability calculated analyzed.Amplitudes CAEPs MT significantly larger compared with PT for frequencies centered...
To evaluate the viability of disentangling a series overlapping 'cortical auditory evoked potentials' (CAEPs) elicited by different stimuli using least-squares (LS) deconvolution, and to assess adaptation CAEPs for stimulus onset-asynchronies (SOAs).Optimal aperiodic sequences were designed controlling condition number matrices associated with LS deconvolution technique. First, theoretical considerations assessed in simulations which multiple artificial responses recovered. Second,...

To determine if one-octave multitone (MT) stimuli increase the amplitude of cortical auditory-evoked potentials (CAEPs) in individuals with a hearing loss when compared to standard pure-tone (PT) and narrow-band noise (NBN).CAEPs were obtained from 16 hearing-impaired adults response PT MT auditory centered around 0.5, 1, 2, 4 kHz NBN 1 2 kHz. Hearing impairment ranged mild moderate both ears. Auditory monaurally delivered through insert earphones at 10 20 dB above threshold. The root mean...
The Acoustic Change Complex (ACC), a P1-N1-P2-like event-related response to changes in continuous sound, has been suggested as reliable, objective, and efficient test of auditory discrimination. We used magnetoencephalography compare the magnetic ACC (mACC) more widely mismatch field (MMF). Brain responses 14 adults were recorded during mACC MMF paradigms involving same pitch vowel synthetic sound. Analyses peak amplitudes revealed significant interaction between stimulus paradigm: for MMF,...
Objective: This study describes a new automated strategy to determine the detection status of an electrophysiological response.Design: Response, noise and signal-to-noise ratio cortical auditory evoked potential (CAEP) were characterised. Detection rules defined: when start testing, conduct subsequent statistical tests using residual as objective criterion, stop testing.Study sample: Simulations run optimal parameters on large combined CAEP data set collected in 45 normal-hearing adults 17...
Abstract Some people using hearing aids have difficulty discriminating between sounds even though the are audible. As such, cochlear implants may provide greater benefits for speech perception. One method to identify with auditory discrimination deficits is measure thresholds spectral ripple noise (SRN). Previous studies shown that behavioral of SRN was associated perception, and also related cortical responses acoustic change or ACCs. We hypothesized ACCs could be directly In this study, we...
A novel experimental paradigm, “deconvolution of ears' activity” (DEA), is presented which allows to disentangle overlapping neural activity from both auditory cortices when two stimuli are closely together in time each ear. Pairs multi-tone complexes were either binaurally, or sequentially by alternating presentation order ear (i.e., first tone complex the pair one and second other ear), using stimulus onset asynchronies (SOAs) shorter than response length. This timing strategy creates...
