Unlabelled: Age-related hearing loss is common among older individuals and is linked to cognitive impairment and a decrease in overall quality of life. Although hearing aids enhance auditory capabilities, their influence on cognitive performance in the Indian context has not been thoroughly investigated. This study investigates the cognitive benefits of hearing aids in elderly Indian patients with age-related hearing loss. A prospective cohort study was conducted at a tertiary care centre between January 2021 and December 2022. The study included 200 elderly patients who were fitted with behind-the-ear (BTE) or receiver-in-canal (RIC) hearing aids. The assessment of cognitive function was conducted using two standardised tests: the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA). The assessment of quality of life was conducted using the WHOQOL-OLD questionnaire, while hearing acuity was examined by pure-tone audiometry and speech perception tests. Data were collected at baseline, 6 months, and 18 months. Multiple linear regression analysis identified predictors of cognitive outcomes. There were significant enhancements in MMSE, MoCA, HHIE, and WHOQOL-OLD scores across the 18-month duration ( < 0.001). The pure-tone audiometry thresholds and speech perception scores demonstrated significant improvement ( < 0.001). Regression analysis indicated that baseline cognitive function, hearing ability, and quality of life were significant predictors of cognitive outcomes at 18 months. No severe cognitive impairment or other confounding severe medical conditions were reported. This study revealed that the use of hearing aids has a substantial positive impact on cognitive function, quality of life, and hearing ability in the older Indian population suffering from age-related hearing loss. Timely intervention and the availability of hearing aids are essential for improving cognitive health and overall well-being in this demographic. Future study should look into the consequences and influence of various hearing aid models.

Hearing aids (HAs) have been used for standard high-frequency hearing loss and tinnitus, but their effects on speech intelligibility in noise (SIN) in people with normal hearing, including hidden hearing loss (HHL), have been little explored. We included in a prospective cohort study patients who experience poor SIN and have normal pure tone average in quiet conditions or slight HL. We used open-fit HAs.

Purpose: Children develop social-pragmatic understanding with the help of sensory, cognitive, and linguistic functions by interacting with other people. This study aimed to explore (a) associations between auditory, demographic, cognitive, and linguistic factors and social-pragmatic understanding in children who use bilateral hearing aids (BiHAs) or bilateral cochlear implants (BiCIs) and in typically hearing (TH) children and (b) the effect of the group (BiHA, BiCI, TH) on social-pragmatic understanding when the effects of demographic, cognitive, and linguistic factors are controlled for.
Method: The Pragma test was used to assess social-pragmatic understanding in 119 six-year-old children: 25 children who use BiHAs, 29 who use BiCIs, and 65 TH children.
The Benefits of Hearing Aids for Adults: A Systematic Umbrella Review.

Department of Health Sciences, Faculty of Medicine Health and Human Sciences, Macquarie University, North Ryde, New South Wales, Australia.
Objectives: This umbrella review aims to summarize the major benefits of hearing aid usage in adults by synthesizing findings from published review articles.
Design: A comprehensive search of databases, including MEDLINE, EMBASE, PsycINFO, and Google Scholar, was conducted. The search was limited to English-language review articles published between 1990 and 2023, focusing on hearing aid outcomes in at least 5 adults (aged ≥18 years).

Background: Individuals with hearing impairments may face hindrances in health care assistance, which may significantly impact the prognosis and the incidence of complications and iatrogenic events. Therefore, the development of automatic communication systems to assist the interaction between this population and health care workers is paramount.
Objective: This study aims to systematically review the evidence on communication systems using human-computer interaction techniques developed for deaf people who communicate through sign language that are already in use or proposed for use in health care contexts and have been tested with human users or videos of human users.
