Generalized transaural stereo and applications. The fact that similar results were observed in each of three listening environments supports the conclusion that the observed results are not idiosyncratic to any particular environment, such as the anechoic chamber, but results will likely generalize across many environments. Besides the extremely dry listening conditions of the anechoic chamber, tests were completed in a reverberation chamber, and in a moderately dry audio surround production studio, typical of the controlled acoustics featured in many critical listening spaces. It was found that the creation of elevated virtual sources was possible using the two surround-channel speakers or using all five ear-level speakers, and the resulting elevated virtual source imagery was compared with the source imagery associated with sound reproduced via speakers that were actually well elevated above the listener's ear level.

The primary question of interest was that regarding whether the elevation of virtual sound sources could be modulated in a simple fashion using only the five ear-level speakers that form a conventional 5.1 channel surround-sound speaker layout. Employing an array of nine speakers, five of which were at the listener's ear level, and four of which were elevated well above the listener's ear level, an experimental investigation of virtual sound source elevation was completed in each of three reproduction environments.
