ITU-R Working Party 11A predetermined experimental conditions, such as test material, camera type and viewing distance. The results show that the detectable thresholds are 45 ms for sound advance and 125 ms for sound delay relative to the vision signal ; and the acceptable threshold are 90 ms for sound advance and 185 ms for sound delay.
