Summary:The principle of the noise control device was described in the 1st report and the fundamental design method of the device was explained in the 2nd and 3rd reports. It is known from these studies that the acoustic design of the pipes composing the device is very important for studying the noise reduction region produced by the device ; and each pipe of the device has frequency selectivity. Therefore, it is necessary to study how the noise reduction region depends on a frequency, and how each pipe of the device contributes to the noise reduction region. These results are described in this paper.
