In what year did James West and Gerhard Sessler create the electret condenser microphone?
Answer
1962
James West and Gerhard Sessler successfully developed the electret condenser microphone in 1962 while working at Bell Labs. This invention represented a major technological shift, as it utilized a permanently charged dielectric material, which successfully eliminated the need for the bulky external polarizing voltage required by previous condenser microphone designs.
