Objectives
Narrative objectives1
To investigate efficient hearing aid fitting methods, adjust hearing aids so that the functional gain is 1/3 gain and investigate whether proper fitting has been achieved.

Assessment
Primary outcomes
The hearing aids will be auditioned for two weeks, and the effectiveness of hearing aid fitting will be evaluated based on sound field testing (hearing aid fitting threshold and speech intelligibility) to determine whether appropriate hearing aid fitting was achieved.

Interventions/Control_1
Based on the results of the most recent pure tone audiogram, the patient is fitted with a hearing aid set up using the prescription formula (DSL version 5) and the threshold is measured in the sound field. From the results of the pure tone audiometry test, determine the 1/3 gain and calculate the difference from the functional gain at 250, 500, 1000, and 2000 Hz, respectively. Perform a hearing test using a hearing aid with gain values adjusted so that this difference is zero.
