vs 75 end-address condensers
More output than 41% 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 48% 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 spec sheet d, p. 3.
Captioned "Typical on and off-axis response of DPA 4018". DPA's product page says on axis was measured at 30 cm and the other directions in the far field; the sheet does not say. Drawn solid from 40 Hz to 18 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 spec sheet d, p. 4. Approximate
Captioned "Typical directional characteristics of DPA 4018"; 5 dB per ring, centre -25 dB. Measuring conditions not stated.
Approximate: reading error up to about 1 dB; some frequencies are identified by reasoning, not by the legend: 250 Hz, 1k Hz, 2k Hz.
