    Noise Reduction in a Tractor Cab by Sound Absorption

      摘要
    • 摘要: 试验表明,简易式驾驶室内噪声较高的主要原因之一是内部混响比较严重。该文在对国产某50型轮式拖拉机驾驶室内的混响特性及其内部噪声进行试验分析的基础上,对驾驶室内吸声材料的选择、使用及吸声性能进行了分析,对吸声降噪进行了设计计算和试验研究

       

      Abstract: Reverberation is one of the main causes of heavy noise in simplified tractor cab. Based on the acoustical measurement in a tractor cab, a suitable sound absorbing material was applied to internal surface of the cab after the full consideration of acoustical characteristics inside the cab. The predicted noise reduction was in good agreement with the measured results.
