The present invention relates to generating aerosols. In order to provide an improved aerosol generation with enhanced user friendliness an aerosol generator (10) is provided that comprises an aperture structure (12) comprising a plurality of apertures a transducer (14) a reservoir space (16) for receiving a liquid from which liquid droplets are to be generated in order to produce an aerosol and a control unit (18). The reservoir space is arranged adjacent to the aperture structure. The transducer is configured to generate a vibrational movement to be transferred as a relative movement between the liquid and the aperture structure. The control unit is configured to activate the transducer to vibrate for a first period having a first time to generate a relative movement between a liquid and the aperture structure the movement being in a transverse direction to the aperture structure to urge liquid through the plurality of apertures to produce a plurality of droplets and to pause the transducer for a second period having a second time and to continuously repeat the activation and pause in an alternating manner. The control unit is further configured to randomly vary at least the second time for a following repeat loop at least after a determined maximum number of repetitions.
