Measurements were undertaken in a variety of control rooms with a system utilizing a compact microphone array and sound intensity technique to estimate the direction of early reflections. This paper presents the results of these measurements including 3D intensity plots that provide a visual representation of sound arrivals at the listener position. The effectiveness of this type of system for the detection of problematic reflections and the evaluation of the listening environment is discussed.
