Frequency response

Angle
Distance

Frequency response: from the spec sheet, p. 3. As printed: "(dB)" from -10 to -60; the on-axis level at 1 kHz (about -26.5 dB) is near the stated sensitivity of -28 dB re 1 V/Pa. Distance, field and smoothing not stated.

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, p. 2. Rings every 2 dB, labelled 0 to -30 dB; 0° at the top. Drawn as two half-circles: 1, 10 and 20 kHz on the left, 50 and 100 kHz on the right; the pattern is taken as symmetric. Measuring conditions not stated. Approximate reading error up to about 1 dB.
