The existing Howling cancel technology is almost using notch filter effect to normalize frequency response. This method is not possible to gain up over 0 dB. Akihiro Yamaguchi made presentation and demonstration for his new method 'Adaptive Howling canceller' which is possible to cancel howling in case of over 0 dB gain. His speech was public addressed by this Adaptive howling canceller system. All Q & A conversation with 20 attendees and Akihiko Yamaguchi (no headset microphone) was easy to communicate very clearly on each other without any howling problem with one omni microphone and speaker in a meeting room.
