Cinema playback levels are calibrated with pink noise and C-weighting.

Evidence

In movies standardized playback sound levels apply to the dubbing stages in which soundtracks are mixed and cinemas in which they are reproduced (SMPTE RP200-2012). The measurements are made using a broadband pink noise test signal and a C-weighted sound pressure level measurement, with the meter set to slow response. — Toole, Floyd E, Sound reproduction- the acoustics and…, 851
