摘　　要：船载强声广播系统是利用舰船作为搭载平台进行远距离广播宣传和近距离驱离的设备,对系统的语音广播和驱离的距离分析是进行系统设计的关键环节。针对船载强声广播系统,基于有效语音广播和驱离距离的战术指标要求,确立了实现驱散效果和进行有效语音广播最低声压级,在此基础上建立了1 m处最大声压级、系统最大功率等技术指标的计算方法,对于系统设计具有很好的指导意义。The shipborne long range acoustic system utilizes ship as the platform. It can broadcast at long range and drive out people at close quarters. For the system, it is important to analyze the distance of broadcasting and driving out. In allu- sion to mission＇ s require of the shipborne long range acoustic system, the minimum sound pressure level for effective voice broadcasting and driving out is established. On the basis of these research results, the method for the technical indexes such as maximum at 1 meter and maximum power of the system is established, which is very important for the system design.
