A statistical energy analysis (SEA) model of a 510 l capacity refrigerator is used to calculate the sound pressure level generated in a reverberation room. This is a reliable indicator of the vibroacoustic performance of the refrigerator, and it is in some countries as a pre-commercialization test. The main contributions of the SEA model are the characterization of the refrigerator structure (three-layer: HIPS, polyurethane foam and steel) and the modelling of important components such as internal chambers or ventilation gratings. The simulation results are successfully compared with laboratory measurements. The SEA model is then used to understand the vibroacoustic behaviour of the refrigerator and to establish the most critical transmission paths and radiation mechanisms.

510升容量冰箱的统计能量分析（SEA）模型用于计算混响室内产生的声压级。这是冰箱电声性能的可靠指标，在某些国家/地区已作为商品化前的测试。SEA模型的主要贡献是制冷机结构的表征（三层：HIPS，聚氨酯泡沫和钢）以及重要组件（例如内部腔室或通风格栅）的建模。仿真结果已成功与实验室测量结果进行了比较。然后使用SEA模型来了解冰箱的振动声行为，并建立最关键的传输路径和辐射机制。
