  Purpose
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.

Condition Intervention
Auditory Processing Disorder, Central Device: Hearing aids

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Evaluation of the Central Auditory Processing in Patients (Elder Than 45 Years Old) With Bilateral Sensorineural Hearing Loss and the Change of the Central Auditory Processing Ability by the Use of Hearing Aids (CAPHA)

Primary Outcome Measures:
  • Change from the baseline in the Hearing In Noise Test (HINT) score at 6 months [ Time Frame: 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.


Secondary Outcome Measures:
  • changes from the baseline in central auditory processing disorder test score at 1, 3, 6, 9 and 12 months [ Time Frame: 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.

  • changes from the baseline in the HINT score at 3, 9, and 12 months [ Time Frame: baseline, 3, 9 and 12 months ]

Enrollment: 27
Study Start Date: July 2013
Study Completion Date: December 2015
Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Hearing aids
Patients who agree to use hearing aids
Device: Hearing aids
Using hearing aids for 12 months
No Intervention: No hearing aids
Patients who did not agree to use hearing aids

Detailed Description:

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
