Screening for recruiting

• 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 ;
