ImmersAV Technology stages hearing experience
- Details
In keeping with the theme of technology to preserve hearing, Bob Schulein, conference co-chair, engineering producer and ImmersAV Technology’s founding partner, organised a demonstration of a new entertainment experience as a part of the conference banquet on Thursday evening. He arranged for Glass Mountain, a Chicago American folk trio, to perform for the guests and to assist in the demonstration of “a unique, binaural audio ‘you-are-there’ experience”.
The band gladly accepted the opportunity and participated in creating and rehearsing for the musical production. For the performance, each attendee was provided with a set of Sennheiser supra-aural wireless headphones and remained in their seat from dinner for the performance. The group performed in front of a single large diaphragm condenser microphone as well as ImmersAV’s binaural mannequin, named Dexter.
As the performance progressed guests were able to compare the headphone reproduction versus that from a two-speaker loudspeaker sound system feeding the output of the single microphone over Dexter’s head. As the trio played a number of folk classics and originals, each attendee heard the audio with natural binaural spatial rendering no matter where they were seated.
The listening experience mimicked being magically transformed directly in front of the band, hearing exactly what Dexter is hearing, with the added benefit of being able to control their own listening volume level. “What a potential boon for night clubs, dinner clubs, theatres, churches and auditoriums, to enhance the listening experience for every person coming through their doors, while listening at one’s own desired level,” says Schulein.
