  • AM0009 Windscreen for 41AM/CN/AL/AO

Introduction

The G.R.A.S. AM0009 is a set of 5 windscreens.  The windscreen is included with the complete windscreens with birdspikes i.e. AM0145, AM0370, and AM0052 but can be replaced separatelly when worn out.

Design

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 G.R.A.S. 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.

Quality & Warranty

G.R.A.S. accessories are made of stainless steel, alloys and high-quality composites. These items are covered by a 2 year warranty respecting their intended use.
