The Detection of Reflections in Typical Rooms

In this study, the effects of reflected sounds were examined as they would occur in stereophonic reproduction in rooms of domestic or control-room size. Thresholds were determined as a function of level relative to the direct sound, the angle of incidence, spectrum, the temporal form of the signal, and reverberation. The relationships between audible effects and measurements, such as energy-time curves and frequency response, are discussed
