Mücərrəd

The purpose of this study is to evaluate the central auditory processing in patients with bilateral sensorineural hearing loss and to observe the change of the central auditory processing ability after using hearing aids.

Təsvir

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

Nəticə

İlkin nəticə tədbirləri

1. Change from the baseline in the Hearing In Noise Test (HINT) score at 6 months [at screening and 6 months after starting hearing aids use]

HINT measures a person's ability to hear speech in quiet and in noise. In the test, the patient is required to repeat sentences both in a quiet environment and with competing noise being presented from different directions.

İkincili Nəticə Tədbirləri

1. changes from the baseline in central auditory processing disorder test score at 1, 3, 6, 9 and 12 months [at screening, 1, 3, 6, 9, and 12 months after starting hearing aids use]

The central auditory processing disorder test is composed of three subtests; duration pattern test, frequency pattern test and dichotic words test. The patient is required to discriminate long duration sound from short one and high frequency sound from low one, and to repeat two words that are given simultaneously.

2. changes from the baseline in the HINT score at 3, 9, and 12 months [baseline, 3, 9 and 12 months]
