High Noise Level Microphones Used in Aircraft

Abstract

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.
