AI Article Synopsis
- The study evaluated the effectiveness of three hearing aid apps (EarMachine, Sound Amplifier, and Petralex) in patients with mild hearing loss.
- The results indicated that conventional hearing aids provided better sound amplification and performance compared to the apps, especially at certain frequencies.
- While some apps showed slight improvements in word recognition, they did not enhance users' ability to hear in noisy environments.
Article Abstract
Background: The aim of this study was to evaluate the behavioral performance of a selection of currently available hearing aid apps in patients with mild hearing loss.
Methods: We investigated 3 user-friendly hearing aid apps (EarMachine, Sound Amplifier, and Petralex) with real-ear measurement, warbletone audiometry, word recognition testing in unaided and aided conditions, and hearing-in-noise tests in quiet and noise-front conditions in a group of users with mild hearing impairment (n=7) as a pilot for a future long-term investigation. Results from the apps were compared with those of a conventional hearing aid.
Results: Hearing aids showed greater gain at 1 and 3 kHz than hearing aid apps in real-ear insertion gain of real-ear measurements. Hearing aids tended to have greater gain than hearing aid apps at 2 and 3 kHz in the sound field audiometry test. The clinical performance of the listeners tended to be better when using a hearing aid and Petralex (13% and 6% improvement in word recognition score, respectively), while EarMachine and Sound Amplifier conferred limited user benefit. The hearing aid apps did not improve signal-to-noise ratio in comparison with the unaided condition in the hearing-in-noise test.
Conclusions: Some hearing aid apps were beneficial for patients with mild hearing loss in terms of amplification, but participants using the apps showed no improvements in hearing-in-noise tests.

Division of General Internal Medicine and Primary Care, Brigham and Women's Hospital, Boston, Massachusetts.
Importance: Nearly all Medicare Advantage (MA) plans offer dental, vision, and hearing benefits not covered by traditional Medicare (TM). However, little is known about MA enrollees' use of those benefits or how much they cost MA insurers or enrollees.
Objective: To estimate use, out-of-pocket (OOP) spending, and insurer payments for dental, hearing, and vision services among Medicare beneficiaries.

Presbycusis, also referred to as age-related hearing loss, poses a substantial burden on both individuals and society. The hallmark of presbycusis is a progressive decrease in auditory sensitivity. Irreversible hearing loss occurs due to the limited regenerative capacity of spiral neurons and peripheral cochlear hair cells (HCs).

Background: Hearing level reference values based on the results of recent audiometry have not been established for the general population of South Korea. This study aimed to evaluate the mean hearing levels of each age group and to measure the annual progression of hearing loss.
Methods: We used the database of the eighth and ninth Korea National Health and Nutrition Examination Survey from 2020 to 2022, and included participants with normal tympanic membranes and without occupational noise exposure.
Development of measures to assess listening-related effort and fatigue in daily life among hearing aid users: protocol for a quantitative field trial.
BMJ Open

Introduction: Individuals with hearing loss and hearing aid users report higher levels of listening effort and fatigue in daily life compared with those with normal hearing. However, there is a lack of objective measures to evaluate these experiences in real-world settings. Recent studies have found that higher sound pressure levels (SPL) and lower signal-to-noise ratios (SNR) are linked to increased heart rate and decreased heart rate variability, reflecting the greater effort required to process auditory information.

This study aims to describe the stress levels experienced by parents of children with hearing loss who use conventional hearing aids or cochlear implants, and to assess the correlation between parental stress and the auditory skills acquired by the children. The study was conducted at the Policlinic "Gaetano Martino" in Messina, evaluating data from 42 pairs of parents of children using hearing aids or cochlear implants. Parents completed the LittlEARS Auditory Questionnaire (LEAQ) and the Parental Stress Scale (PSS) 18 months after the initial device (hearing aid or cochlear implant) had been activated.
