vs 75 end-address condensers
More output than 20% of 75 end-address condensers.
Each stripe is one end-address condenser with a published sensitivity, and each bar counts them; further right means more output. This mic is in blue.
vs 104 end-address condensers
Quieter than 19% of 104 end-address condensers.
Each stripe is one end-address condenser with a published self-noise, and each bar counts them; further right means quieter. This mic is in blue.
vs 110 end-address condensers
Takes louder sound than 27% of 110 end-address condensers.
Each stripe is one end-address condenser with a published max SPL, and each bar counts them; further right means it takes louder sound. This mic is in blue.

Proximity effect: the bass it gains up close
From the response image.
Captioned (on the product page) "Typical on and off-axis response of a 2011A microphone. On-axis (0°) measured at 30 cm (11.8 in), other directions measured in the far field." Drawn solid from 50 Hz to about 17 kHz, dotted outside.
Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.
Polar pattern
From the polar image. Approximate
Captioned (on the product page) "Typical directional characteristics of a DPA 2011A Cardioid Microphone"; 5 dB per ring, centre -25 dB. Measuring conditions not stated.
Approximate: reading error up to about 1 dB.
