Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* Among patients who are visiting for hearing disturbance, patients with bilateral sensorineural hearing loss will be included after audiologic tests, history taking and physical examination.
* audiologic tests: pure tone audiometry, speech audiometry, impedence audiometry, distortion product otoacoustic emission, auditory brainstem response.
Dividing into "Hearing aids" group and "No hearing aids" group
* The use of hearing aids will be recommended to all included patients.
* Hearing aids group: patients who want to be prescribed hearing aids (28 subjects)
* No hearing aids group: patients who do not want to be prescribed hearing aids (28 subjects)
Audiologic test
* Hearing in noise test (HINT), central auditory processing disorder test
* at screening, 1, 3, 6, 9 and 12 months after starting hearing aids use
