以某大型浮式生产储油卸油装置(Floating Production Storage and Offloading,FPSO)为例,确定其公共广播和通用报警(Public Address and General Alarm,PAGA)系统声压计算所需参数及相关参数的估计值,介绍室内和室外声压计算方法.在没有软件的前提下,通过计算公式确定某个房间或某个位置的各声响装置(喇叭/扬声器)所需电功率,为类似项目的PAGA系统的声压计算提供参考.
Sound Pressure Calculation Method and Application for FPSO PAGA System
Taking a large Floating Production Storage and Offloading(FPSO)as an example,the necessary design parameters and estimated values of the sound pressure calculation for Public Address and General Alarm(PAGA)system are determined,and the indoor and outdoor sound pressure calculation methods are introduced.The required electrical power of each sound transducers(horns/speakers)in a room or location by calculation formulas are calculated with no relevant software available,providing reference for PAGA system sound calculation in similar projects.
