Abstract
A teleconferencing bridge simulates the auditory spatial ambience of a face-to-face conference. This bridge uses a novel binaural approach to simulate spatial ambience.

9. A method of teleconferencing with binaural discrimination for each of n conferees, where n is an integer greater than two, comprising the steps of
amplifying speech from a first of said conferees, amplifying speech from a second of said conferees, amplifying speech from a third of said conferees, providing the amplified speech of said first conferee along a first path, providing the amplified speech of said first conferee, delayed a time duration t1, along a second path, providing the amplified speech of said second conferee along a third path, providing the amplified speech of said second conferee, delayed a time duration t2, along a fourth path, providing the amplified speech of said third conferee along a fifth path, providing the amplified speech of said third conferee, delayed a time duration t3, along a sixth path, combining the provided amplified speech from one of said first and said second paths, from one of said third and said fourth paths, and from one of said fifth and said sixth paths, into a first combination, combining the provided amplified speech from the other of said first and said second paths, from the other of said third and said fourth paths, and from the other of said fifth and said sixth paths, into second combination, suppressing the amplified speech of said one of said first and said second paths from said first combination, and directing the resulting suppressed combination along a first line to said first conferee, suppressing the amplified speech of said other of said first and said second paths from said second combination, and directing the resulting suppressed combination along a second line to said first conferee, suppressing the amplified speech of said one of said third and said fourth paths from said first combination, and directing the resulting suppressed combination along a third line to said second conferee, suppressing the amplified speech of said other of said third and said fourth paths from said second combination, and directing the resulting suppressed combination along a fourth line to said second conferee, suppressing the amplified speech of said one of said fifth and said sixth paths from said first combination, and directing the resulting suppressed combination along a fifth line to said third conferee, and suppressing the amplified speech of said other of said fifth and said sixth paths from said second combination, and directing the resulting suppressed combination along a sixth line to said third conferee.
