摘要
在言语测听中,信号校准非常重要。言语测听中用言语听力级(dB HLspeech)表示信号强度。国家标准中规定了两种对各语音测试项进行均一化的方法。本文介绍了实际言语测试中的强度控制和校准的实现方法。
Signal intensity calibration is very important in speech audiometry. Intensity of speech test signal is expressed in dB Hearing Level for Speech (dB HLspeech) . Two test intensity normalization methods for test items in speech audiometry materials were specified in national standard GB/T 17696-1999. In this article, the methods to calibrate and control speech signal intensity in speech audiometry practice were introduced
