The Effect of Low Frequency Reflections on Stereo Images
This paper looks at the amount of absorption required to adequately control early reflections in reflection-controlled environments at low frequencies (< 700 Hz). This is where the Inter-aural Time Delay Cue (ITD) is important. Most work has focused on wideband energy time performance. In particular, it will derive the effect a given angle and strength of reflection has on the phantom image location using the Blumlein equations. These allow the effect of reflections as a function of frequency to be quantified. It will show that the effect of reflections are comparatively small for floor and ceiling reflections, but that lateral reflections depend on the phantom image location and get worse the more off-center the phantom image becomes.
