<p>Speech signal-produced peak-values of speech levels and speech signal-produced minimum-values of speech levels are recorded in such a way that, after recording of a peak value or minimum value, this value is gradually reduced or increased until a new peak value exceeds the instantaneous recording threshold or a new minimum value falls below the instantaneous recording threshold. From the relevant current peak-value recording threshold values or minimum-value recording threshold values, a level regulation value is obtained by an adjustable reduction or increase, whereby the two level regulating values are combined together to form a level threshold value.</p> |
