摘要
针对目前我国摩托车普遍存在噪声大 ,乘坐舒适性不理想这一难题 ,利用声强测量分析方法对摩托车噪声源进行了识别 ,得出了其声场分布规律 ,快速准确地找到了主要的噪声源。在此基础上提出了具有针对性的降噪措施 ,使该摩托车行驶加速噪声显著降低。表明声强测试分析方法是一种有效的摩托车噪声源识别和声场分析方法。
Point to now our country motorcycle omnipresent noise big,ride comfortable porperty non ideal this 1nut,on sound intensity measure analyse methodic to motorcycle noise source carry on identify,obtain his or its voice distributiving law,rapidly exactly find mainly noise source.Here on basic up bring forth having pertinency steer down chirp measure,keeping motorcycle ride speeding up noise marked reduce.Indicate sound intensity test analysis methodic is a sorl of efficacious motor-bike noise source identifying harmony analyse methodic.
