No. The whole specification was developed in order to be consistent with subjective estimates of the disturbing effect of noise signals on programme signals. Both the attack and decay time-constants are necessary in order to evaluate impulsive signals correctly. -- Regards, John Woodgate, OOO - Own Opinions Only.
