Delivering binaural stimuli with loudspeakers through crosstalk filters avoids the intrinsic artifacts of using headphones in localization experiments. However, one must first demonstrate that such a system is equivalent to that of a real soundfield. This study demonstrates that listeners did not perceive any meaningful difference between a real sound source at 0 degrees and a virtual rendering using crosstalk cancellation from a pair of loudspeakers at ±90 degrees. Three different stimuli were used: single bursts of wideband noise, click trains, and repeated harmonic pulses. Listeners could not discriminate between the two cases using a forced-choice paradigm.
