抄録

The sound arresting effect against high sound of a muffler having sound absorbing walls was examined theoretically and experimentally. The experiments were also made to find sound arresting effects when the muffler has a mass of sound absorbing materials inwardly. As a result, it was found that the use of sound absorbing materials was very effective for the practical purpose, too. In that case the muffler was to be so constructed that the sound absorbing materials could be easily removable.
