摘要
言语测听法采用专门编制的测听词表来检查患耳的言语识别率。应用滤波言语测听词表增加了测试信息的难度,能够发现中枢神经听功能的缺陷。本文采用FIR滤波器对标准的言语测听词表进行数字滤波,生成各种滤波言语测听词表。
Speech audiometry adopts special testing speech tables to measure patient' s speech discrimination score. A filtered testing speech tables increases the difficulty of testing information. It is easy to find the listening functional disorder of central nervous system. In this paper, we used FIR digital filter to process the testing speech tables and created kinds of filtered testing speech tables.
