GRAS AM0052 Complete Windscreen for 41AM/CN

Material: Foam and stainless steel

Technology

Introduction

The windscreen is mounted over the microphone and preamplifier.

Design

The AM0052 is a complete windscreen with stainless steel birdspikes which prevents birds from landing on the windscreen.

When a microphone is placed in a laminar flow, turbulence is created which in turn results in unwanted pressure variations on the diaphragm. By using a windscreen the pressure variations are moved as far away from the diaphragm as possible.

Theoretically this supports a “the-bigger-the-better design”, but in practice it is a compromise between air speed reduction, practical size and self-induced noise. Self-induced noise is wobble-noise which is generated, when the windscreen starts moving around the microphone.

The GRAS windscreens are all size optimized and their special, open-cell foam structure and number of pores per inch2 (ppi), are designed to resist a humid environment and at the same time not influence the sound pressure measurement result significantly.

Note: The foam part can be purchased separatelly. See GRAS AM0009 (set of 5 pcs).
