KN95 mask attenuation of white noise—1/3 octave band analysis. Note: Intensity attenuation of KN95 mask on white noise, presented by 1/3 octave bands. Negative values indicate lower intensity when played through the mask compared to noise not played through the mask. Red dashed line = low/high-frequency cutoff A; Green dashed line = low/high-frequency cutoff B
