Home / Neumann 007268 Windscreen WS 81 Windscreen made out of open-cell polyurethane foam
Product Overview
The WS 81 (007268) is designed to match the specific acoustic requirements of interference tube microphones. Its elongated cylindrical shape is optimized to cover the side-entry ports of the shotgun mic, which are highly sensitive to wind. By using a specialized porous structure, the WS 81 breaks up turbulent air streams before they reach the capsule. Despite its high efficiency, it is acoustically transparent, maintaining the microphone’s sharp directivity and natural frequency response with a negligible impact on the high-end "shimmer."
Product Description
The Standard for Location Dialogue:
In film and electronic news gathering (ENG), the microphone is often in constant motion on a boom pole. This movement creates a "self-wind" that can ruin a recording with low-frequency thumps. The WS 81 is tested in turbulent air streams of 20 km/h to ensure it can handle these rapid pans and tilts. By providing 25 dB of attenuation, it allows boom operators to follow the action without fear of subsonic interference.
Acoustic Transparency for Shotgun Precision:
Shotgun microphones rely on precise phase cancellation to achieve their directional pickup. The WS 81 uses a premium open-cell foam that does not interfere with this process. It introduces only a subtle 3 dB attenuation at 15 kHz, ensuring that dialogue remains crisp and articulate. Unlike generic foam covers, the WS 81 does not cause muffling or "boxiness," preserving the off-axis rejection that makes the KMR 81 i so effective.
Physical Protection in the Field:
Beyond its acoustic properties, the WS 81 acts as a physical barrier. Field recording often exposes microphones to dust, light rain, and humidity. The WS 81 helps shield the delicate internal electronics and the interference tube from these elements, extending the lifespan of your professional gear. Its snug, secure fit ensures it won't slide off during active use in the field.
Tailored Fit for the KMR Series:
The WS 81 is specifically designed for microphones with a 21 mm diameter and an elongated body. It is the factory-recommended accessory for:
Neumann KMR 81 i (Short Shotgun Microphone)
Neumann KMR 81 D (Digital Shotgun Microphone)
