摘　　要：声校准器是一种重要的声学计量器具。依据国家计量检定规程《JJG176— 95》,声校准器需要对声压级、频率和谐波失真度 3个指标进行检定。本文论述了利用计算机控制检定设备对上述 3个指标进行智能化检定的方法及程序设计。Sound etalon is an acoustic measurement equipment of great significance according to the National Measurement Calibration Standards——JJG176-95, a sound etalon is required to conduct calibration in three indexes, i.e., SPL (sound pressure level), frequency and harmonic distortion. This essay presents method and program design for intelligent calibration in the above mentioned three aspects though involvement of computer control.
