The system includes software that controls a set of eight (currently) speakers that are positioned in space. We have two hardware setups for our project: the first is an umbrella that the speakers are mounted on, in which the listener sits beneath. The second is a wooden disk that is suspended from the ceiling. This setup allows the user to spin freely between the speakers.<\/div>\n<div><\/div>\n<p>&nbsp;<\/p>\n<div>Our three experiences are listed below:<\/div>\n<p>&nbsp;<\/p>\n<div><\/div>\n<div><strong>Suspended Motion II<\/strong><\/div>\n<p>&nbsp;<br \/>\n<!-- AB Video: Invalid clip_id --><\/p>\n<p>&nbsp;<\/p>\n<blockquote>\n<div>We have improved on the existing <i>Suspended Motion<\/i> project by incorporating our eight channel setup. Images from this new setup can be seen below. We are also still in the process of finding a chair that optimizes the experience. Many of the chairs we have tried are noisy or do not spin as freely as we would like.

We&#8217;ve\u00a0made acrylic enclosures for all the speakers, as well as designed an acrylic amplifier box which houses an amplifier array along with a charging circuit and a Li-ion battery. The battery powered amp-box gives us the mobility we&#8217;d like to make use of later. All wiring and circuits have been shifted from the breadboard to stripboard\/veroboard and everything has been kept modular to allow quick assemble\/dis-assembly. For the disk setup, all hardware is mounted onto a flat wooden surface as shown in the pictures above. Finally, shielded speaker wires were used to avoid any cross-talk.<\/p>\n<p>&nbsp;<\/p>\n<\/div>\n<div><\/div>\n<div>\n<div><strong>Group Members:<\/strong><\/div>\n<div>M Haris Usmani (Persistent Member)<\/div>\n<div>Robert Kotcher<\/div>\n<div>Haochuan Liu<\/div>\n<div>Liang He<\/div>\n<div>Meng Shi<\/div>\n<div>Wanfang Diao<\/div>\n<div>Jake Berntsen<\/div>\n<\/div>\n<div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Introduction: The multi-channel sound system group is implementing a spatial instrument that allows us to interactively experience sound in space.
