    STC performance fails most often at the assembly not the door slab.

    1. Inadequate Seals

    Issue: Incomplete perimeter seals or incorrect seal type (fire vs. acoustic)
    Impact: Sound bypasses the door leaf; STC reduction of 5–15 points

    2. Gaps & Clearances

    Issue: Excessive undercuts, uneven jamb gaps, misaligned frames
    Impact: Minor gaps (1–2 mm) allow sound flanking and acoustic leakage

    3. Hardware Vibration

    Issue: Loose closers, rattling latches, improper closer settings
    Impact: Structure-borne noise and reduced speech privacy

    4. Installation Accuracy

    Issue: Frame not plumb/square; inconsistent seal compression
    Impact: Uneven seal engagement and unpredictable STC performance
