本标准描述了如何确定家用扬声器的频率响应、方向性和最大输出能力。它旨在确定扬声器的音频性能，而不是扬声器在给定输入信号下的生存能力。本标准仅适用于扬声器系统，不适用于原始传感器。

This standard describes how to determine the frequency response, directivity and maximum output capability of a residential loudspeaker. It is intended to determine the audio performance of a loudspeaker, not the loudspeaker's ability to survive a given input signal.This standard applies only to loudspeaker systems, and not to raw transducers.
