With the rapid development of automotive industry, the demands for in-car vibro-acoustic com-fort are continually increasing.There are two main directions for quantitative evaluation of in-car noise:subjective e-valuation and objective quantized model based on psychological acoustic indexes. The former is not objective, with its outcomes usually not universally relevant,while the latter is still hard to meet the requirements of sound evalua-tion for different individuals,since people are the ultimate evaluator after all. A large number of studies show that e-lectroencephalogram (EEG) technique can objectively reflect human subjective feelings, such as emotions and fa-tigue etc. In this paper,EEG technique is introduced into the evaluation of in-car noise. EEG characteristic parame-ters are used to reflect the occupant annoyance caused by in-car noise,with the relationship between EEG character-istic parameters and the degree of annoyance established.%随着汽车产业的飞速发展,对车内声振舒适度要求不断提高.车内噪声的量化评价主要沿着主观评价和基于心理声学评价指标的声品质客观量化模型两大方向.前者不够客观,评价结果不具有普适性;但人是最终评价者,后者仍难以满足声音评价因人而异的要求.大量研究表明,脑电方法能客观反映人的主观感受,如情绪和疲劳等.本文中将脑电方法引入车内噪声评价,利用脑电特征参数客观反映车内噪声造成的乘员烦恼度,构建脑电特征参数与烦恼度的关系.
