摘　　要： 提出了多点激励测量汽车车内噪声声响感度的方法。通过理论及实验分析，指出了传统方法所存在的试验结果受激励力影响的问题。实际应用表明：该方法能够有效地降低汽车结构非线性等因素造成的误差，提高测量分析的精度及效率。 There were some drawbacks in the measurement of acoustic sensitivity by vector synthesis method for vehicle's interior noise; that is, the results of measurement are influenced easily by excitation forces,the method is carried out using the multi-point excitation. It is verified that this method, which can reduce the errors caused by nonlinearities and data processing, is better than old one to measure the acoustic sensitivity accurately in practice.
