The polar patterns illustrated above represent the locus of points in polar coordinates that produce the same signal level output in the microphone if a given sound pressure level (SPL) is generated from that point. How the physical body of the microphone is oriented relative to the diagrams depends on the microphone design.
Because of a strong correspondence between the spherical harmonics and microphone polar patterns, and the fact that those polar patterns have clearly defined directions, it seemed natural to order and name the components in the same way as the axes of a right-hand coordinate system.
A common polar pattern for microphones is the cardioid. This has a single direction in which the microphone does not respond to impinging sound waves. Highly directional (shotgun) microphones have more complex polar patterns. These microphones have a large, narrow lobe in the main direction of sound reception but also a smaller lobe in the ...

Neumann U 87 with shock mount. Introduced in 1967 as the solid-state successor to the U 67, [4] [5] [1] Neumann introduced the U 87 alongside the KM 86, KM 84, and KM 83 as part of the company's first 'FET 80' series of microphones that utilized use solid-state FET electronics that didn't require separate power supplies or multi-pin power cables and allowed the mics to be made smaller.

Microphones have a polar pattern describing their sensitivity as a function of the direction of the incident sound. Many microphones have an omnidirectional polar pattern which means their sensitivity is independent of the direction of the incident sound. Microphones with other polar patterns exist that are more sensitive in a certain direction.
Lip-ribbon microphones use baffles to create an acoustic labyrinth within the body of the microphone. [1] The microphone's bi-directional polar pattern controls interference; sound from the commentator reaches one side of the ribbon more than the other, whereas sounds from other sources contact both sides of the ribbon (at a difference in phase of 180°) and cancel out.
