Abstract

In one embodiment of the invention a method includes (a) operating a combustion engine at a first activity level corresponding to a first noise level; (b) charging an accumulator with a first pressure input; (c) lowering engine activity level of the engine to a second activity level corresponding to a second noise level that is lower than the first noise level; and (d) seismic sweeping with the vibrator based on the first pressure input and lowering engine noise from the first noise level to the second noise level.
