Abstract:
A dummy sound absorber representing a human being used for measuring a sound absorption power of a chair to simulate what the sound absorption power of the chair would be with a human being seated thereon in a predetermined position and having a predetermined weight, the dummy sound absorber comprising:a chair contacting portion having a shape which is substantially equivalent to a shape of portions of a human being which would be in contact with a seat and a back portion of the chair if the human being is seated on the chair in the predetermined position; sound absorption power generation means for generating a sound absorption power which is substantially equivalent to a sound absorption power generated by a human body wearing a predetermined type and amount of clothing and when seated on the chair in the predetermined position; and pressing force generation means for generating a pressure exerted by the dummy against the back and the seat of the chair that is substantially equivalent to the weight that would be exerted against the back and the seat of the chair by the human being if the human being of the predetermined weight is seated on the chair in the predetermined position.
