There are a few formulas for the cavity-type mufflers aimed to reduce the noise radiating form an open end to free space. In this paper, the authors have attempted to establish more precise formulas for the attenuation of such mufflers. The attampt has been completed with success and it is now shown that those formulas given in the articles on mufflers can all be derived from the general equations given in this paper.
