Claim 9:
10. A method for enforcing noise level limits at a worksite comprising:
accessing, in electronic memory, time-specific maximum noise limit data specific to the worksite, the time-specific maximum noise limit data including maximum noise limit levels for different periods of time for the worksite;
providing, using one or more electronic processors, control signaling to control a plurality of autonomous working machines at the worksite during a continuous work period; and
in response to said providing the control signaling, and depending upon whether in a first period of time or a second period of said different periods of time, either
controlling each of the autonomous working machines in a first noise-optimized mode according to first defined machine operation parameters previously identified to yield different sound characteristics no louder than a first maximum noise limit level of said maximum noise limit levels, or
controlling each of the autonomous working machines in a second noise-optimized mode according to second defined machine operation parameters previously identified to yield different sound characteristics no louder than a second maximum noise limit level of said maximum noise limit levels,
wherein, for each said autonomous working machine, maximum productivity and sound output levels in the first noise-optimized mode are greater than maximum productivity and sound output levels in the second noise-optimized mode.
