Explanation A cardioid microphone, commonly used for vocals or speech, is designed to pick up sound in front of the microphone but reject sound coming from behind the microphone. It gets its name from the fact that its polar sensitivity pattern is heart-shaped as shown in the given figure. The polar graph shows how sensitive the microphone is in picking up sound coming from different angles. The maximum sensitivity is at 0°, which is directly in front of the microphone. At other angles, the microphone is less sensitive, and therefore, there is a decrease in decibels (dB). For example, at 30° to either side, there is about a 1-dB drop, and at 90°, the decrease is about 7 db. And at 120°, the decrease is about 13 db...
