Problem
The microphone capsule is positioned under a thick jacket layer, making consonants noticeably less intelligible than the same mic outside the garment.
Solution
Root Cause / Diagnostic:
Thick wool, leather, or synthetic jacket fabric creates acoustic damping that severely attenuates high frequencies above 3 kHz. Concealing the mic beneath dense cloth muffles speech sibilance, reducing dialogue clarity and vocal presence.
Actionable Fix:
1. Reposition the capsule to the outer lapel edge, tie knot, or shirt collar exposed to open air.
2. If wardrobe requires full concealment, apply a high-shelf boost (+3 to +5 dB at 6 kHz) on the preamp or DSP channel strip.
3. Compare the concealed audio against an external boom reference; verify consonant intelligibility scores on test phrases.
Pro Tip:
Use acoustic mesh mounts (Bubblebee Piece-A-Fur) that hold fabric off the capsule while allowing high frequencies to pass unimpeded.
