Frequency response

Angle
Distance

Frequency response: 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

Polar pattern: from the spec sheet d, p. 4. 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.
