Just a quick one: It seems to me that a dome could be interesting used as a kind of wavefield synthesis device.
Domes have the interesting property of focussing sound at a point that is opposite the source, as it were. So you can create a 'holosonic' point source right next to someone's ear Dr. Peter Lennox School of Technology, Faculty of Arts, Design and Technology University of Derby, UK e: p.len...@derby.ac.uk t: 01332 593155 -----Original Message----- From: sursound-boun...@music.vt.edu [mailto:sursound-boun...@music.vt.edu] On Behalf Of Neil Waterman Sent: 18 February 2013 16:47 To: Surround Sound discussion group Subject: [Sursound] Any experience with dome acoustics? Greetings, Does anyone on the list have prior experience installing ambi-based 3D sound into 'dome' shaped replay environments? Any tips, specifically on speaker placement, approaches, etc. The problems I am facing include a 12 foot 240 degree partial dome made of fabric, an 18 foot 240 degree partial dome using fiberglass and a much bigger 40 foot 360 degree full dome in fiberglass. All of the above will actually be 1/2 domes in the sense they are not full spheres, but 1/2 a sphere resting on the ground. My only prior experience was with a full sphere, fibre dome that was a nightmare to put sound into... One option for the 40 foot dome is to use a central cluster of directional speakers, hung in a "chandelier" that would use the dome surface as a virtual speaker through reflection, but I have never tried this. My concern with this is that the listeners (who will be roughly central in all these dome areas) will hear both the direct sound and reflected sound and end-up with a confused mess. For all of these domes there will be an 18" skirt area below the dome that could be used for loudspeakers around the periphery - is it better to try to beam the sound directly at the listeners position, or perhaps use a more diffuse speaker, facing up into the dome face? There will be space to get at least one speaker overhead for all configurations.
