What this Trial Is About
This study compares the hearing improvement effects of domestic hearing aids and imported hearing aids in 80 patients with moderate to severe and severe age-related hearing loss. Patients will be randomly assigned to either the experimental group (domestic hearing aids) or the control group (imported hearing aids) and will undergo a 30-minute trial. Pure Tone Average (PTA) and Speech Recognition Threshold (SRT) will be measured both before and after the trial. The improvements in PTA and SRT will be calculated.The market prices of the hearing aids and the degree of hearing improvement in decibels will be recorded. These data will be used to conduct a comprehensive cost-effectiveness analysis. After the trial, the International Outcome Inventory for Hearing Aids (IOI-HA) and the Abbreviated Profile of Hearing Aid Benefit (APHAB) will be used to assess the benefits of the hearing aids.
