Looking into the plasma/laser paper and it mentions 77.2 dB at an insanely close 22mm distance. Background was 55.7. http://arxiv.org/pdf/1506.06668v1 Page 9. It sounds (hah) like it wouldn't be pleasant if you have your head near a full display in operation, especially since the noise scales with the resolution/brightness. It would be interesting to see how quickly the noise drops off over distance. You are looking at something between a home sound system, vacuum cleaner, or highway traffic at that volume level. Tolerable but not pleasant.

The abstract of the paper being discussed, "Fairy Lights in Femtoseconds: Aerial and Volumetric Graphics Rendered by Focused Femtosecond Laser Combined with Computational Holographic Fields": "We present a method of rendering aerial and volumetric graphics using femtosecond lasers. A high-intensity laser excites a physical matter to emit light at an arbitrary 3D position. Popular applications can then be explored especially since plasma induced by a femtosecond laser is safer than that generated by a nanosecond laser. There are two methods of rendering graphics with a femtosecond laser in…
