I asked both ChatGPT & google Gemini about the effectiveness of wool felt, as I am in the process of isolating my components. Both agree. Attached is the response from chatGBT.
Benefits of Wool Felt Isolation:
- Gentle Damping:
Wool felt provides light mechanical damping, especially for mid-to-high frequency microvibrations. It’s soft and compressible, helping absorb some surface-born energy. - Surface Protection:
Prevents scratching and can act as a barrier between metal, glass, or wood surfaces. - Non-Resonant:
Wool doesn’t “ring” like rubber or plastics can. It has a natural absorptive quality.
⚠️
Limitations in Your System:
- Poor Low-Frequency Isolation:
Wool is not effective at isolating against bass-born vibrations (e.g., from your subwoofer or room modes), which are most problematic in audio gear. - No Load Handling or Decoupling:
Wool doesn’t decouple components from shelves. It compresses too easily under weight, especially heavy gear like the BHK or 330A, and doesn’t return to shape predictably. - No Layered Damping or Directionality:
Unlike Herbie’s, IsoAcoustics, or Symposium products, wool lacks engineered damping layers, so its effect is subtle and not optimized for audio bandwidth.
