Über die Wahrnehmbarkeit mehrerer Rückwürfe von Sprachschall

Utilizing speech sound, investigations were made on the perceptibility of a synthetic acoustical reflection in the presence of one or more additional reflections coming from various directions. The results lead to an answer to the question, which reflections in a room will not be perceptible at all. The possibility of a synthetic electroacoustical representation of the complete series of perceptible reflections in a room is discussed.
