Problem
A lavalier capsule rubs against a shirt collar during head turns, creating intermittent clothing rustle that cannot be removed without damaging speech.
Solution
Root Cause / Diagnostic:
Physical friction occurs when a lavalier capsule or its upper boot touches stiff collar fabric or button seams during cervical rotation. The high-frequency scratch travels acoustically into the omnidirectional diaphragm and mechanically down the capsule housing.
Actionable Fix:
1. Sandwich the capsule inside moleskin, a vampire clip, or an Rycote Overcover between the inner fabric layers away from rubbing seams.
2. Create a strain-relief broadcast loop in the mic cable taped securely with transpore tape to decouple mechanical vibrations.
3. Have talent turn their head 90 degrees left and right at full vocal volume while listening on closed-back headphones to verify silence.
Pro Tip:
Mounting the lavalier inverted (pointing downward) drastically reduces clothing scrape and plosive breath pops while retaining identical frequency response.
