Abstract: This paper discusses the use of the computational fluid dynamics (CFD) for computational analysis of microphone wind noise. The first part of the work, presented in this paper, discusses the behavior of the flow around the microphone. One of the practical questions answered in this work is the well-known difference between “pop noise,” i.e., noise caused by transient flows, and wind noise generated by more stationary flows. It appears that boundary layer separation and related modification of flow field near the boundary is a significant factor in transient flow noise, while vortex shedding, emerging at higher flow velocities, is significant for steady state flow. The paper also discusses the effects of the geometrical shape and surface details on the wind noise.
