Clean air supply mechanical sound and vibration comparator
Separate acoustic diaphragm/lever/stylus and contact vibration pickup with manually read trace, isolated reference excitation mount, physical time/displacement comparison and protected test support. Candidate earlier architecture only; acoustic calibration, response bandwidth, low amplitude sensitivity, loading and repeatability unresolved. Cannot presently claim to accept whole clean-air supply noise duty.

Capability requirements and tolerances
Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.
Parts and Tools needed
No researched inventory yet. This is an unexpanded frontier; an empty list does not mean the item can be obtained directly from nature.
What remains unresolved
- Manufacture, quantities, suitability and complete inventory remain unreviewed.
