The paper summarizes a method for determining reflection locations from the room impulse response by using an ellipse to represent an equal delay contour. Applications of the equal delay contour are extended to represent an electronic artificial reflection surface designed for the Anderson Chamber Hall, Binghamton University. The results obtained from reflection measurements are compared to theoretical calculations and differences are accounted for by application of elliptical contours.
