Research on a Noise Control Device : 3rd Report, The Fundamental Design of the Device (2)

Abstract

The structural design method of the noise control device was described in the 2nd report and it is possible to design the structure of the device by this method. But it is necessary to decide how to place the device for a noise source when it is applied. That is, an appropriate position for the noise source is required in order to obtain better noise reduction effect. Therefore, the design method for placing the device was considered through some model experiments in an anechoic room and the field, and the prediction method of the sound pressure level in the case of using the device with a barrier was investigated. The results are described in this paper.
