Abstract (in Japanese) (See Japanese page) 
(in English) This paper will deal with the subjective effects of active noise control(ANC) system. To design a highly effective ANC system, and to improve its performance to create a "better sound environment", it would be essential to observe a reaction and a response of the human to the system, and we have been working on this area with various approach mainly based on the psychological acoustic. However, we have recently started applying different parameters for the subjective evaluation, and at last InterNoise, we have reported that physiological signals from human's body, such as a reaction time to the short-term memory task, and the saliva cortisol, would have a chance to show us subjective response to the low-frequency noise reduction. So we have continued these discussions, and also tried to obtain the relationship between those physical parameters and the subjective response, especially subjective sound impression to the ANC environment.
