Claim 0:
1. A system for controlling a plurality of mobile autonomous machines at a worksite comprising:
non-transitory computer-readable memory to store 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; and
control circuitry operatively coupled to the non-transitory computer-readable memory, the control circuitry being configured to
set a continuous work period for the mobile autonomous machines at the worksite,
when the continuous work period is in a first period of time of said different periods of time, control each of the mobile autonomous machines at all times in a first noise-optimized mode according to a first plurality of different sets of defined machine operation parameters each previously identified to yield different sound characteristics no louder than a first maximum noise limit level of said maximum noise limit levels stored in the non-transitory computer-readable memory, each of the different sets of defined machine operation parameters of the first plurality corresponding to respective first operational tasks performed by the mobile autonomous machine, and
when the continuous work period is in a second period of time that is non-overlapping with the first time period of said different periods of time, control each of the mobile autonomous machines at all times in a second noise-optimized mode according to a second plurality of different sets of defined machine operation parameters each previously identified to yield different sound characteristics no louder than a second maximum noise limit level of said maximum noise limit levels stored in the non-transitory computer-readable memory, each of the different sets of defined machine operation parameters of the second plurality corresponding to respective second operational tasks performed by the mobile autonomous machine,
wherein, for each said mobile autonomous 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.
