The invention provides a method for dynamic determination of time constants to be used in a detection of the signal level of an input signal of unknown level in an electric circuit, comprising the following steps:-feed the input signal through an auxiliary level detection means that is reacting faster to changes in the input sound signal level than the detection of the signal level as a whole,-feed either the input signal or the output of the auxiliary level detection means through a guided level detection means, which is arranged with a guided time constant, and where the guided level detection means outputs an estimate of the level of the input signal,-analyze the outputs of the auxiliary and the guided level detector means, determine the time constant of the guided level detection means based on this analysis.
