Comparing Hearing Improvement Between Domestic and Imported Hearing Aids in Adults Aged 60 to 85 With Moderate to Severe Age-Related Hearing Loss

What this Trial Is About

Researchers are evaluating the hearing improvement effects of domestic versus imported hearing aids in patients with moderate to severe and severe age-related hearing loss. This non-inferiority, single-blind, randomized controlled trial involves 80 patients who will be randomly assigned to use either domestic hearing aids from the Bigsound brand or imported hearing aids from the Phonak brand. The study aims to compare hearing improvements and cost-effectiveness between the two types of hearing aids. Participants will use their assigned hearing aids for a 30-minute trial. Both domestic and imported hearing aids include behind-the-ear, neck-worn, and in-the-ear styles, with the domestic devices being rechargeable. The study collects data on Pure Tone Average PTA and Speech Recognition Threshold SRT before and after the trial, and records the market price and degree of hearing improvement in decibels. After the trial, patient benefits are assessed using the International Outcome Inventory for Hearing Aids IOI-HA and the Abbreviated Profile of Hearing Aid Benefit APHAB. During the study, participants will undergo hearing tests before and after using the hearing aids. Researchers will analyze hearing and speech improvements, patient satisfaction, and adaptation in various listening environments. The study also includes a cost-effectiveness analysis of the hearing aids. The total participation time includes the 30-minute hearing aid trial and post-trial assessments, with the study ending by December 2025.
