In 1973, Kohler Co. completed the construction of a semi-anechoic chamber, to be used for the acoustical analyses of its small-engine (4-24 HP) line. This paper discusses the acoustical response characteristics of Kohler Co.'s semi-anechoic chamber. The chamber is first evaluated as a system. Then, an analysis of the room's sound absorptive wedges is discussed.
