A method enables the time required to complete a seismic survey and the noises recorded in the seismic data to be reduced. One aspect of the method includes actuating a first vibrator group to start a first sweep at time T0; and a second vibrator group to start a second sweep at time T1, wherein T0<T1<T0+S1+L, where S1 is a sweep time of the first vibrator group and L is a listening time; wherein the time between the first sweep and the second sweep is T1-T0>=((n-1)*f1*S1)/(n*(f1-f0)) where n is a natural number, f0 is the lower frequency limit of the vibrator sweep and f1 is the upper frequency limit of the vibrator sweep.
