Core idea: Inspect seals, doors, hardware and resilient details over time.
Door seals
Compression and alignment change with use.
Cracks
Movement and new cables can create leakage paths.
Mounts
Vibration isolators can settle or become bridged.
Records
Keep drawings, photographs and product data.
A practical planning sequence
- Describe the source, timing and frequency character.
- Trace direct and flanking paths.
- Set a realistic improvement goal.
- Compare complete systems and local requirements.
- Document the baseline and inspect details during work.
- Repeat the same test afterward.
