Figure 1

Boxplots of aerosol number emission rates (0.25–35.15 μm size range) by instrument class and type, including vocalists. Instruments are ordered by median emission rate with participant data as open circles; boxes delineate the inter-quartile range (IQR) and whiskers extend to 1.5⋅IQR or the data minimum. The dashed horizontal line represents a method quantification limit (8.3 particles s−1). Data are background corrected.
