本标准规定了耦合器型声学校准器的性能要求。对于可能与校准器一起使用的每种话筒类型，要求包括耦合器中的声压级、声音频率，以及确定大气压力、温度、湿度和磁场对校准器产生的声音的压力级和频率的影响。在各频率和声压级下，应在规定的公差范围内满足规范要求。

This standard specified performance requirements for coupler-type acoustical calibrators. For each microphone type that may be used with the calibrator, requirements include the sound pressure level in the coupler, the frequency of the sound, and the determination of the influence of atmospheric pressure, temperature, humidity, and magnetic fields on the pressure level and frequency of the sound produced by the calibrator. specifications are to be met within stated tolerances at each frequency and sound pressure level of operation.
