    "limitations": [
      "15 dB below the finer WM-HG03 at the same frequency: the larger aperture is the cost of the 70% open area",
      "Two-layer figures require both layers bonded and offset; simply laying a second layer loosely does not reproduce the declared 55 dB",
      "Requires grounding for low-frequency electric fields and correct bonding because the material is highly conductive",
      "The number is a flat-sample laboratory value, not a prediction of what a meter will read in a finished room"
