Headphone Response: Target Equalization Trade-offs and Limitations

耳机响应:目标均衡的取舍和局限

 

The effects of headphone response and equalization are examined with respect to the influence on perceived sound quality. Free field, diffuse field, and hybrid real sound field targets are shown and objective response data for a number of commercially available headphones are studied and compared. Irregular responses are examined to determine the source of response anomalies, whether these can successfully be equalized and what the limitations are. The goal is to develop a robust process for evaluating and appropriately equalizing headphone responses to a psychoacoustically valid target and to understand the constraints.

耳机的响应及均衡效果,可以通过聆听音质结果去检测。本文展示了自由场,扩散场,以及介于二者之间的混合型实际声场的目标响应,并研究和对比了一批商业耳机的客观响应数据。同时,对不正常响应结果进行分析以确定这些异常响应的来源,并且判断是否可以通过调整均衡设置来改善异常响应现象,如果不能调整,那么要确认调整过程中的局限。这些测试的目标是为了开发一套有效的程序,从心理声学的角度评估耳机响应并做适当的均衡,同时明确约束条件。
