Importance Hearing loss treatment delays cognitive decline in high-risk older adults. The preventive potential of addressing hearing on incident dementia a community-based population adults, and whether it varies by method measurement, is unknown. Objective To calculate the attributable fraction associated with adults to investigate differences age, sex, self-reported race, measurement. Design, Setting, Participants This prospective cohort study was part Atherosclerosis Risk Communities...
Objectives: To examine speech intelligibility and listening effort in a group of patients with single-sided deafness (SSD) who received cochlear implant (CI). There is limited knowledge on how effectively SSD-CI users can integrate electric acoustic inputs to obtain spatial hearing benefits that are important for navigating everyday noisy environments. The present study examined quiet noise simultaneously measuring using pupillometry individuals SSD before, 1 year after, CI activation. was...
Bilateral cochlear implants (BiCIs) result in several benefits, including improvements speech understanding noise and sound source localization. However, the benefit bilateral provide among recipients varies considerably across individuals. Here we consider one of reasons for this variability: difference hearing function between two ears, that is, interaural asymmetry. Thus far, investigations asymmetry have been highly specialized within various research areas. The goal review is to...
Importance Speech recognition outcomes with a cochlear implant (CI) are highly variable. One factor suggested to correlate CI-aided speech is frequency-to-place mismatch, or the discrepancy between natural tonotopic organization of cochlea and electric frequency allocation CI electrodes within patient’s cochlea. Objective To evaluate association mismatch in large cohort postlingually deafened adult users, while controlling for various clinical factors known be associated those outcomes....
The current study examined the neural mechanisms for mental effort and its correlation to speech perception using functional near-infrared spectroscopy (fNIRS) in listeners with normal hearing (NH). Data were collected while participants listened responded unprocessed degraded sentences, where words presented grammatically correct or shuffled order. Effortful listening task difficulty due stimulus manipulations was confirmed a subjective questionnaire well-established objective measure of -...
The ability to attend target speech in background noise is an important skill, particularly for children who spend many hours noisy environments. Intelligibility improves as a result of spatial or binaural unmasking the free-field normal-hearing children; however, use bilateral cochlear implants (BiCIs) demonstrate little benefit similar situations. It was hypothesized that poor auditory attention abilities might explain lack observed with BiCIs. Target and interferer stimuli were presented...
The measurement of pupil dilation has become a common way to assess listening effort. Pupillometry data are subject artifacts, requiring highly contaminated be discarded from analysis. It is unknown how trial exclusion criteria impact experimental results. present study examined the effect criterion, percentage blinks, on speech intelligibility and measures in 9 participants with single-sided deafness (SSD) 20 normal hearing. Participants listened repeated sentences quiet or maskers. trials...
Bilateral cochlear implants (BiCIs) can facilitate improved speech intelligibility in noise and sound localization abilities compared to a unilateral implant individuals with bilateral severe profound hearing loss. Still, many BiCIs do not benefit from binaural the same extent that normal (NH) listeners do. For example, redundancy, derived having access duplicate copies of signal, is highly variable among BiCI users. Additionally, patients loss commonly report elevated listening effort NH...
Web-based remote testing can increase access to clinically diverse populations in hearing research. However, whether affects data quality compared in-lab is unknown. Data for binaural tasks may be particularly vulnerable commercial-grade hardware limitations and background noise from the environment. We replicated two published studies on abilities using a web-based behavioral experimental platform (Gorilla.sc). In Experiment 1, we an experiment by Goupell et al. [JASA 133(4) (2013)] that...
Web-based testing is an appealing option for expanding psychoacoustics research outside laboratory environments due to its simple logistics. For example, participants partake in listening tasks using their own computer and audio hardware can participate a comfortable environment of choice at pace. However, it unknown how deviations from conventional in-lab affect data quality, particularly binaural hearing that traditionally require highly precise presentation. Here, we used online platform...
Abstract Estimates range from 2-8% of dementia cases in the US are attributable to hearing loss. Here, we investigate measurement considerations quantifying population fraction (PAF) loss highlight how differences methodology can underestimate PAF. We use two cohort studies older adults US: National Health and Aging Trends Study (NHATS), a nationally-representative sample Medicare beneficiaries; Atherosclerosis Risk Communities (ARIC) Study, large, community-based study with longitudinal...
