초록

In order to make a quiet zone, one can consider various methods. Of the methods, this paper deals with the method using control materials such as absorption materials. This method controls sound fields by changing boundary conditions. First, this paper shows that the control material is essentially on the same road as active noise control (ANC) That is, we can consider the control material as the control source of ANC. However we cannot control the source strength. Second, this paper shows that the position of the control material is an important variable by a numerical simulation. And the strategy to optimize the position is addressed.
