What is automated abnormal-noise testing, and which products suit it?
Automated abnormal-noise testing replaces the human ear at end of line with a quiet acoustic environment, microphone capture, algorithmic judgement, and automatic sorting. The unit runs inside an acoustic enclosure, its sound is captured, software decides whether an anomaly is present, and the result drives OK/NG sorting. It suits any product with moving parts where noise maps directly to user experience: window regulators, wiper motors, compressors, washing-machine motors, vacuum motors, vibration motors, cooling fans, smart speakers, robot vacuums, servo motors, and precision gearboxes.
Key points
- Four elements: low-noise enclosure, microphone capture, algorithmic judgement, automatic sorting
- Best fit is products with moving parts whose noise reaches the user directly
- Background noise stability matters more than peak attenuation figures
- Automated judgement removes the operator-to-operator variation of listening tests
- Enclosure plus excitation plus decision logic is one integrated process, not three purchases
