摘要
从技术和实际应用角度,结合国内外相关标准,对扩声系统声压级的设置进行了论述。分析了不同声压级的主观感受和高声压级的限制情况。针对声压级标准提出了修改意见。
Combining with the national and foreign related standards, the selection of SPL（Sound Pressure Level） of sound reinforcement system is discussed in terms of technique and implement. The subjective attitude of different SPLs and the restriction of high SPL are analyzed. The modification proposal for the standard of SPL is presented.
