1. Small Air-moving device, such as bowlers and axial fans.
2. IT relative products, such as notebook, which have fans or coolers inside.
3. Audio system, such as loud speaker, which can generate strong vibration to affect their sound quality.
1. Cross check with SPL, SWL, or SQ, to detect structure-borne noise
2. Displayed in FFT, time-history graph
3. Tri-axial measurement
