A seat moving machine comprises a passenger seat assembly disposed in between opposing seat supports which raise and lower the passenger seat assembly. One or more passenger seat beam rotators are operative to rotate the passenger seat assembly to change the pitch independently of the raising and lowering. In embodiments, rather that the seat rows being pivoted up with a rotating floor, a rotate function alters their mutual positions to one another while the lift function is taking place which brings the back seat rows up and over the front seat rows, allowing control over mutual row position during lift and in the show. Though no cables are involved, by combining the motions of lift and rotate and without any further equipment, an immersive theater system comprising the seat moving machine still employs seating that is suspended.

Disclosed is a control system for controlling a plurality of user terminals. The control system includes at least: a control device including a processor, and configured to determine a command to be executed by the plurality of user terminals located in a concert hall or stadium; a transmitter configured to transmit a wireless signal corresponding to the determined command; a plurality of receivers, each of which is connected to a respective user terminal of the plurality of user terminals, receives the wireless signal, and transmits the received wireless signal to the respective user terminal; and the plurality of user terminals, each of which is configured to perform a command corresponding to the wireless signal transmitted from a respective receiver of the plurality of receivers.

Methods and systems for arranging audience members and musicians are described herein. An assembly of seats for an event location includes a plurality of musician seats and a plurality of audience seats. Each audience seat of the plurality of audience seats can be disposed in a particularly designated location on an event location surface relative to the plurality of musician seats such that each audience seat of the plurality of audience seats has an audience immersion score that is above a threshold minimal acceptable audience immersion score (MAAIS). The audience immersion score includes a musician adjacency component, a conductor position depth offset component, and a conductor position lateral offset component.

Exemplary air amplifiers described herein can utilize a high-pressure stream of gas to accelerate a low-velocity stream of gas to provide a high-velocity, high-volume stream of gas. This high-velocity, high-volume stream of gas can generate unwanted noise as the high-velocity, high-volume stream of gas propagates through the air amplifier. The exemplary air amplifiers described herein can include can passively and/or actively suppress, for example, diminish, re-tune, or even completely cancel, the unwanted noise as the high-velocity, high-volume stream of gas propagates through these exemplary air amplifiers. The exemplary air amplifiers described herein can include one or more absorption materials to passively suppress the unwanted noise generated by the high-velocity, high-volume stream of gas. The exemplary air amplifiers described herein can generate multiple noise suppression waves to actively suppress the unwanted noise generated by the high-velocity, high-volume stream of gas. The multiple noise suppression waves can destructively combine with the unwanted noise generated by the high-velocity, high-volume stream of gas to suppress the unwanted noise.
