James Edward Maceo West Invented the Foil Electret Microphone in 1962 while developing instruments for human hearing research


  

 

James Edward Maceo West 

 (born February 10, 1931 in

 Farmville, Prince Edward County, Virginia)

 

 

Along with Gerhard Sessler, West invented the foil electret microphone in 1962 while developing instruments for human hearing research.[3]

 

  Compared to the previous condenser microphones, the electret microphone has higher capacitance and does not require a DC bias. 

 

[4] West and Sessler optimized the mechanical and surface parameters of the system.[5]
