Vibration Analysis Equipment: Human Vibration & Structural Monitoring
Norsonic vibration analysis instruments measure human exposure to whole-body and hand-arm vibration per ISO 8041, and structural vibration for construction impact surveys, building monitoring, and machinery diagnostics. Available from Norsonic Asia for projects across ASEAN, South Asia, and the GCC.
Human Vibration Measurement — ISO 8041
- Whole-body vibration (WBV) — measures daily vibration exposure A(8) m/s² against EU Directive 2002/44/EC EAV (0.5 m/s²) and ELV (1.15 m/s²)
- Hand-arm vibration (HAV) — 8-hour equivalent acceleration A(8) for occupational health and safety compliance
- Frequency weightings: Wk (vertical seat WBV), Wd (horizontal WBV), Wh (hand-arm), Wm (motion sickness)
- Vibration dose value (VDV) — for intermittent, impulsive, and shock vibration environments
- MTVV (maximum transient vibration value) — captures peak vibration for shock-exposed workers
Building Vibration Surveys — ISO 4866
- Construction vibration impact assessment — piling, sheet piling, blasting, demolition near sensitive structures
- Peak particle velocity (PPV) measurement and comparison with DIN 4150-3 and BS 7385 damage limits
- Traffic-induced building vibration compliance — road and rail sources
- Machinery vibration transmission through structures — pump, HVAC, and production equipment
- Heritage structure monitoring — vibration limits for protected buildings and archaeological sites
