Aerosol control: This is a multiplier calculated as mediantest setup /medianbaseline and is used to characterise the efficiency of aerosol control in the given setup. The lower the value, the lower the elevation compared to baseline and the more efficient the control.
EOS, extraoral scavenger device; TNC, total number concentration.
