The objective of this paper is to do a comparative
analysis of three of the present "State of the Art" high
noise level microphones. They are the M-87/AIC and
M-87/AIC+ (EV 693) both made by Electro-Voice and the HNL
bone conduction microphone made by SETCOM Corporation.
The advantages and disadvantages of using a bone
conduction microphone over a boom mounted microphone are
also investigated.
