1. An aerosol-generating device, comprising:
a cavity configured to receive an aerosol-generating article comprising aerosol-forming substrate;
a first air inlet fluidly connected with the cavity and configured to enable ambient air to be drawn into the cavity;
a second air inlet fluidly connected with the cavity and configured to enable ambient air to be drawn into the cavity; and
airflow controlling means for controlling one or both of airflow through the first air inlet and the second air inlet,
wherein the airflow controlling means is configured to control a cross-sectional area of one or both of the first air inlet and the second air inlet,
wherein the airflow controlling means is further configured as a perforated element,
wherein each perforation of the perforated element corresponds to a different cross-sectional area,
wherein the perforated element comprises a first set of perforations and a second set of perforations, and
wherein the first set of perforations corresponds to the first air inlet and the second set of perforations corresponds to the second air inlet.
