KK133 capsule head - omnidirectional diffuse field
with height increase in the free sound field (4-5 dB at 12 kHz). The attached sound diffraction ball causes a very uniform increase in height, combined with increasing directivity. The frequency response in the diffuse sound field is flat up to 12 kH
lateral indentation, which is realized with only one membrane. The membrane diameter is only 16 mm. All sound components act directly on this membrane. This results in identical frequency responses and transfer mass at 0°. and180°

Free-field equalized pressure receiver: The transfer rate is flat in the free sound field up to 20 kHz, but drops above 5 kHz in the diffuse sound field.

Pressure gradient receiver with wide cardioid polar pattern. The attenuation is 4 dB at 90°, 8 dB at 135°; and 11 dB at 180°. The frequency response curves for sound incident from the front (±90°) are parallel up to 12 kHz.

An acoustic depth reduction in the open field serves to suppress low-frequency interference. The close-up effect, which is physically caused by pressure gradient microphones, results in a flat frequency response when talking at close range from a dis
