Music ability testing system for electronic cochlea implant persons

Abstract

The invention relates to a music ability testing system for electronic cochlea implant persons. The system can divide the music ability test into five subtests of rhythm, pitch, timbre, cantus and familiar music through the separation and combination for different composing elements of music, and specifically comprises a test module (1), a music material database (2) and a music ability test experiment database (3), wherein the test module (1) is composed of a rhythm resolution test module (11), a pitch differential threshold differentiating module (12), a cantus outline recognizing test module (13), a music instrument timbre differentiating module (14) and a familiar music differentiating test module (15), the music material database (2) is used for providing music test materials, and the music ability test experiment database (3) consists of a database for recording contents and results of test experiments of the test module (1) and an information base of electronic cochlea implant persons who participate in the experiments.

Description

technical field [0001] The invention relates to the field of cochlear electronics, in particular to a music ability testing system for cochlear implanters, especially suitable for Chinese post-linguistic cochlear implanters. Background technique [0002] Cochlear implant technology is currently the only neuroprosthetic that can restore hearing to the deaf. By directly stimulating the auditory nerve with electric current, the deaf can restore their hearing. It has helped more than 120,000 cochlear implant recipients around the world restore their hearing to varying degrees. The primary problem that cochlear implants need to solve is speech communication, so it is not difficult to understand that the traditional signal processing strategy is also called "speech coding strategy". In the past 10 years, the speech recognition of cochlear implant recipients in a quiet environment has reached a good level, and more than half of the implant recipients can successfully conduct teleph...

Problems solved by technology

[0005]However, there is still a lack of relevant research in China. Due to the differences in educational background and cultural habits, it is not possible to directly copy foreign test methods

For example, the Montreal Battery for Evaluation of Amusia (Montreal Battery for Evaluation of Amusia) is a general music ability test item, which can be used for cochlear implanters and normal hearing people. Its disadvantage is that, on the one hand, its The main purpose is not to assess the musical ability of cochlear implant recipients, on the other hand, the test is time-consuming and difficult

In comparison, the University of Washington Clinical Assessment of Music Perception is a clinical test method for cochlear implant recipients. The difficulty and duration of the test are appropriate. cochlear implant users; secondly, in the melody recognition item of the test, the 12 western "familiar melodies" provided cannot be used for domestic research

These deficiencies determine that we cannot directly apply foreign test platforms for testing and research
