Please gently slide/mount on your microphone 'foam' windscreen. Microphone is not included. Deadcat Windscreens (aka windshields) provide a method of reducing the effect of wind on microphones. While pop-screens give protection from unidirectional blasts, furry shield wind into the grille from all directions, and entirely enclose the microphone and protect its body as well. The latter is important because, given the extreme low frequency content of wind noise, vibration induced in the housing of the microphone can contribute substantially to the noise output. The shielding material used, furry fabric, is designed to have a significant acoustic impedance. The relatively low particle-velocity air pressure changes that constitute sound waves can pass through with minimal attenuation, but higher particle-velocity wind is impeded to a far greater extent. Since all wind noise is generated at the first surface the air hits, the greater the spacing between shield periphery and microphone capsule, the greater the noise attenuation. For an approximately spherical shield, attenuation increases by (approximately) the cube of that distance. Historically, artificial fur has proved very useful for this purpose since the fibers produce micro-turbulence and absorb energy silently. If not matted by wind and rain, the fur fibers are very transparent acoustically. In the studio and on stage, fur filters can be useful for reasons of hygiene, and protecting microphones from spittle and sweat. Stating the efficiency of wind noise reduction is an inexact science, since the effect varies enormously with frequency, and hence with the bandwidth of the microphone and audio channel. At very low frequencies (10-100Hz)where massive wind energy exists, reductions are important to avoid overloading of the audio chain, particularly the early stages.
