Objective: The purpose of this study was to investigate the relationship between the amount of time that a person reports wearing his or her hearing aid and the actual time that the hearing aid is worn. Although use time data are used in the analysis and interpretation of investigations concerned with auditory perceptual learning and with user satisfaction, the accuracy of self-reported use time has not been fully investigated.
Design: The experimental and control group were fit with a hearing aid that has the capability of storing use time data for later analysis. The experimental group was told that the self-reported use time would be verified with a computer analysis of the hearing aid that provides the actual use time. The control group was not informed of the use time validation procedure. The agreement between self-reported and actual use time was compared statistically between groups (knowledge of validation versus no knowledge of validation).
Results: The experimental group provided accurate self-reported use time whereas the control group showed a significant difference between actual use time and self-reported use time.
Conclusions: The results may assist in the interpretation of results of previous investigations that have depended on self-reported use time and in the design of future investigations. For the clinician, the results indicate that relying on a patient's self-reported hearing aid use time for documentation of satisfaction or signal processing preference may be misleading.

EXPRESS: The Time Course of Cognitive Effort During Disrupted Speech.
Q J Exp Psychol (Hove)
January 2025
Hearing Aid Laboratory, Northwestern University, Department of Communication Sciences and Disorders Evanston, IL, USA.
Listeners often find themselves in scenarios where speech is disrupted, misperceived, or otherwise difficult to recognize. In these situations, many individuals report exerting additional effort to understand speech, even when repairing speech may be difficult or impossible. This investigation aimed to characterize cognitive effort across time during both sentence listening and a post-sentence retention interval by observing the pupillary response of participants with normal to borderline normal hearing in response to two interrupted speech conditions: sentences interrupted by gaps of silence or bursts of noise.

Int J Audiol

School of Health and Rehabilitation Sciences, The University of Queensland, Brisbane, Queensland, Australia.
Objectives: To explore the extent to which an international sample of adults with hearing loss experience and respond to stigma-induced identity threat; and the associations between experiences of hearing loss stigma, responses to hearing loss stigma (concealment of hearing loss), and hearing aid use.
Design: Cross-sectional online survey comprising published questionnaires and multiple response questions designed to capture five of seven constructs of the Major and O'Brien model of stigma-induced identity threat. Multivariate modelling examined factors associated with hearing aid use and concealment of hearing loss.
Can a Cochlear Implant Be Used as an Electrical Impedance Tomography Device?

The imaging of the live cochlea is a challenging task. Regardless of the quality of images obtained from modern clinical imaging techniques, the internal structures of the cochlea mainly remain obscured. Electrical impedance tomography (EIT) is a safe, low-cost alternative medical imaging technique with applications in various clinical scenarios.

Background: Age-related hearing loss and mild cognitive impairment (MCI) independently increase dementia risk. The Ageing and Cognitive Health Evaluation in Elders randomised controlled trial (RCT) found hearing aids reduce cognitive decline in high-risk older adults with poor hearing.
Methods: This pilot RCT in London memory clinics randomised people with MCI (aged ≥55, untreated hearing loss defined as Pure Tone Average 0.
