The effectiveness of a windscreen depends heavily on the materials used and its construction.

  • Material Choice: High-quality materials like porous foam and synthetic fur minimize the impact on the microphone’s frequency response, while low-quality ones might not offer adequate protection and affect sound negatively.
  • Porosity: More porous materials allow more sound through, preserving high frequencies but providing less wind protection; less porous materials offer more protection but may muffle sound, particularly at higher frequencies.
  • Layering: Combining different materials, such as foam and fur, maximizes wind reduction.
  • Shape and Size: The windscreen must fit snugly to prevent air from reaching the diaphragm, and larger “dead air” spaces offer better protection in extreme conditions. The correct windscreen is one that balances noise reduction and acoustic transparency.
