摘　　要：内燃机的开发利用给我们带来巨大便利的同时,也给我们带来烦躁的噪音,文章通过分析内燃机噪声产生原因,提出降噪措施,并通过采用朗德DATaRec 4 DIC24模块采集系统,开发出一套先进的多通道内燃机噪声测试系统,为内燃机降噪提供准确数据。The development and utilization of the internal-combustion engine bring us great convenience, meanwhile, it also brings us agonizing noise. This paper brings forward noise reduction method by analyzing the noise generation. A suit of advanced noise test system for multichannel internal-combustion engine is developed and it will providing exact datas for engine noise reduction by using Land top DATaRec 4 DIC24 module collection system.
