Objective: This study aimed to examine the status of the supply system for hearing aids at stores in Japan.
Methods: This was a cross-sectional, observational study. We mailed questionnaires to 4502 hearing aid stores in Japan and analyzed the responses.
Results: Of the 4502 stores, 1032 (23%) responded. Most stores accessed audiogram information and adjusted hearing aids using computer fitting software. Overall, 43% of the stores only used the manufacturer's original prescription formula to adjust the hearing aid, and 47% of stores lacked a device for measuring the frequency response of the hearing aids. Moreover, 20% of the stores lacked both a sound field threshold measurement system and a real-ear measurement device. Objective evaluations, including functional gain, rear-ear insertion gain, and frequency response data, were not performed by 14% stores. Speech-language-hearing therapists were present in only 5.6% stores.
Conclusion: The findings revealed several key shortcomings in the hearing aid supply system at hearing aid stores in Japan.

Single-sided deafness (SSD), where there is severe to profound hearing loss in one ear and normal hearing in the other, is a prevalent auditory condition that significantly impacts the quality of life for those affected. The ability to accurately localize sound sources is crucial for various everyday activities, including speech communication and environmental awareness. In recent years, bone conduction intervention has emerged as a promising solution for patients with SSD, offering a non-invasive alternative to traditional air conduction hearing aids.

Background: Sensorineural hearing loss (SNHL) is the most common sensory deficit worldwide. Current solutions for SNHL, including hearing aids, cochlear implants, and hearing assistive devices, do not provide consistent results and fail to address the underlying pathology of hair cell and ganglion cell damage. Stem cell therapy is a cornerstone in regenerative medicine.

The relationship between hearing loss (HL) and Parkinson's disease (PD) remains unclear. Using individual-level and summary-level data from the UK Biobank and the largest genome-wide association studies, we examined this link through observational, Mendelian randomization and genetic pleiotropy analyses. Among 158,229 participants, PD risk rose with HL severity especially in elder and males, and hearing aids significantly reduced PD risk in males.

Objectives: Hearing aids (HAs) are a widely accepted first-line treatment option for individuals suffering from both hearing loss and chronic tinnitus. Though HAs are highly effective at improving speech understanding, their effectiveness in ameliorating tinnitus symptoms is less clear. In recent years, several investigators have reported on attempts to predict HAs effectiveness on tinnitus symptoms using an array of variables.
