Despite thee macabre nickname, a quent quite; dead cat quenquentes; is a dense synthetic fur cover that snaps or slides over thee primary windshield.

Analizy porównawcze: Dead Cat vs. Foam Control

Choosing between foam and fur is nott binary - mott field contributions carry both. The decision depends on wind conditions, mobility requirements, and thee e acceptable trade-off in sound quality. The table below superizes thee key distinctions:

  • Reduction wiatru: Fur covers reduce wind noise by 20- 35 dB at 20 km / h (12 mph) wind speed. Foam reduces by 10- 15 dB under the same conditions.
  • Bardzo częsta konserwacja: Wysoka jakość fur covers produce under 2 dB of high- frequency roll- off. Foam can introdule 3- 5 dB of loss above 5 kHz, especially if te foam im thick or soiled.
  • Handling noise: Fur covers are bulkier and can brush against cables or boom operators contact noise; clothing, generating noise. Foam im s compact and less prone to contact noise.
  • Portability: Foam is lightweight andd fits a pocket. Fur blimps overy a dedicated slot in thee kit bag and may require a hard case.
  • Cost: A foam windshield typically kosztują US $15- $50. A blimp plus fur muff ranges from $200 to $1,200 for profesjonals.
