To reduce the exhaust noise of internal combustion engines, exhaust silencer containing chamber cells are widely used. Cell design largely determines its acoustic efficiency as a function of frequency. Therefore, in this work, a theoretical study of the most frequently used chamber noise-suppressing cells of various designs is carried out. Designs with high acoustic efficiency in a wide frequency range have been determined. The results of the study will allow the designer, using these structures, to synthesize highly efficient ICE exhaust silencers.
