摘　　要：为提高人们对语音干扰声压级的认识,正确理解规范对于公共广播系统声压级的要求。对ISO 9921:2003中关于语音干扰声压级的定义及计算方法进行解读,结合实船上对公共广播系统声压测试方法的试验,对广播喇叭在环境噪音和语音干扰水平背景下的声压级数据进行分析。研究表明:基于语音干扰水平的广播声压测试操作便捷、更贴近人体工程学。研究成果可为其他各类船舶或海洋平台上的公共广播系统声压测试提供一定参考。To enhance understanding of the sound pressure level of voice interference and to correctly comprehend the requirements of standards for the sound pressure level of public broadcasting systems.Interpret the definition and calculation method of sound pressure level for speech interference in ISO 9921:2003,and analyze the sound pressure level data of broadcast speakers under the background of environmental noise and speech interference levels,based on the test of sound pressure testing method for public broadcasting systems on real ships.Research shows that broadcasting sound pressure testing based on voice interference level is convenient to operate and more ergonomic.The research results can provide some references for sound pressure testing of public broadcasting systems on other types of ships or ocean platforms.

关 键 词：语音干扰水平 公共广播系统 环境噪音 声压测试
