Cinema playback level disputes have prompted talk of legal limits
Evidence
Even with a seat count that ranges through 6, 24, 60, 114, 161, 211 and 516, there is no obvious pattern of change in steady-state room curves beyond the small difference in air attenuation in the direct sound. The scaling corrections based on audience size advised in SMPTE ST 202 and ISO 2969 recommendations are incorrect. If the intent was to acknowledge air attenuation as a function of propagation distance, the loss can be easily calculated for any seat in any venue, and it will be different from the straight-line variations suggested in the recommendations (see Figure 10.12). — , Toole, Floyd E - Sound reproduction-…, 1353 (
