Subtle fastening sounds quantify soft-connection defect standards for EV transmission connectors

- Target sound: Connector Clicks
- Key metric: 97.73% (Cycle judgment accuracy)

## Project overview

A case that identifies loose connector fastening through subtle sounds that are hard to hear manually

## Field challenge

- Missed fastening was a high-risk quality issue tied directly to driving stability
- The fastening signal was too small to distinguish reliably by ear
- Work methods and recording conditions kept changing in the field

## Outcome summary

- 97.73%: Cycle judgment accuracy
- 97%+: Fastening sound classification accuracy
- SNR 1.77dB: Subtle signal detection
