The dependence of absorption area of chairs on parameters of their arrangement in a hall is made clear theoretically by making use of a mathematical model of partial spaces between rows of chairs acoustically coupled with the main space of the hall: parameters of their arrangement are the distance between adjacent rows, the number of rows, the number of chairs in a row and the slope of the floor on which chairs are arranged. Comparison between the calculated and the observed absorption areas of chairs both in a reverberation room and two existing halls shows good agreement.
