Abstract

The method involves measuring noise levels during a pause in the warning signals and storing this as a reference noise value. The level of the warning signals (25,55) are then measured during the period when the warning apparatus is active. During this period, the warning signals are adjusted until their measured level exceeds the previously stored noise value by a preset amount. There is also an Independent claim to an apparatus for carrying out the method.
