Discussion on ¿High-quality microphones¿ before the Electronics and Communication Section, 23rd March, 1959
Diagrams other than the cosine diagram are sometimes required for stereophonic purposes, and this has caused the electrostatic microphone , which can have a polar diagram of either the cardioid or cosine type, to return to commercial use.
