Abstract: An example may include detecting, via a controller, one or more microphones and one or more speakers in an area, measuring, via the one or more microphones, an initial frequency response of an audio signal generated by the one or more speakers inside the area and generating an initial room performance rating, comparing the initial frequency response to a target frequency response, creating audio compensation values to apply to the one or more speakers based on the comparison, and applying the audio compensation values to the one or more speakers.

Abstract: A process may include detecting, via a controller, one or more microphones and one or more speakers in an area, measuring audio performance levels of the one or more microphones and the one or more speakers to identify one or more of a noise floor and a reverberation level, identifying an initial room performance rating based on the audio performance levels, applying optimized speaker tuning levels to the one or more speakers and the one or more microphones, measuring, via the one or more microphones, optimized audio performance levels of the one or more speakers based on the applied optimized speaker tuning levels, and generating a report to identify an optimized room performance rating based on the applied optimized speaker tuning.

Abstract: A pneumatic servo comprises a motor having a shaft for rotation in response to an electrical signal. A cam is connected to the shaft for rotation therewith. The cam has an outer profiled periphery and opposite sides. A pneumatic nozzle having an opening for directing a flow of gas toward one side of the cam near the periphery, obscures the flow by different amounts as the cam rotates to create a back pressure in the nozzle comprising a pneumatic signal. A curved projection engages an opposite side of the cam, the projection being aligned with the nozzle opening and reducing oscillation excursions of the servo at gas pressures in the nozzle of above 12 psi.
