发明名称 Method for measuring sound absorption power of a theater chair with a human being seated thereon and a dummy sound absorber
摘要 There is provided a method for measuring a sound absorption power of a theater chair with a human being seated thereon. The method includes steps of disposing a theater chair which is an object of measurement in a measuring environment; disposing a dummy sound absorber in the theater chair, the dummy sound absorber having a shape in which it is in contact with the theater chair, a sound absorption power and a chair pressing force in such a manner that the dummy sound absorber simulates a human being seated on the theater chair; causing changes in the theater chair which changes are substantially equivalent to a change in the state of the theater chair caused when a human being gets seated on the chair and a change in the sound absorption power of the theater chair caused by seating of the human being thereon; and measuring the sound absorption power of the theater chair. There is also provided a dummy sound absorber used for carrying out this method.
