儿童听觉声源定位能力自动测试系统的研制

Research and Development of Automatic Test System for Sound Localization Ability of Children

为评测人工耳蜗植入儿童的听力及语言交流能力,越来越多的学者开始关注声源定位。本文针对儿童在声源定位测试中,配合度低,测试过程复杂等问题,研制一套儿童声源定位自动测试系统。该设计基于安卓设备,根据儿童特点设计趣味交互界面,通过蓝牙设备控制测试声源播放时间及方位,利用移动终端设备自动记录与处理获得的测试数据。测试系统对多例听障儿童进行了测试实验,效果良好,测试数据稳定准确。该测试方式较于传统的测试方法,具有效率高、配合度好、操作简单等优点,定量的测试受试者水平方向的定位能力,便于临床应用。

In order to evaluate hearing and verbal communication skills of cochlear implanted children,an increasing number of scholars began to focus on sound localization. An automatic test system forsound localization ability of children was developed to solve problems like low degree of coordinationand complex testing process during children’s sound localization test. Based on Android system, aninteresting interactive interface was designed catering to children’s characteristics. Bluetooth devicewas used to control the playing time and direction of the testing sound source, mobile terminal devicewas used to automatically record and process the obtained data. A number of hearing-impaired childrenwere tested with this system; good results were achieved with stable and accurate data. Compared withtraditional test methods, this test method has the advantages of high efficiency, high degree of children’scooperation and simple operation, which can be used to quantitatively test the localization ability ofhorizontal direction of subjects and is convenient for clinical application.
