Numerical Simulation of Microphone Wind Noise, Part 3: Wind Screens and Shields

Authors: Backman, Juha

AES Convention 136 · Paper 9062 · April 2014

Abstract

This paper discusses the use of the computational fluid dynamics (CFD) for computational analysis of microphone wind noise. This final part of the study discusses the effect of typical wind shields and pop screens on the flow around the microphone body. The simulations show that although all types of screens share common action mechanisms, moving the vortices generated by the flow further away from the microphone diaphragm and absorbing the vortex energy, the importance of these mechanisms varies with the type and size of the shield. In addition to the flow properties also the effect of different wind shields on the acoustical response of the microphone is discussed.
