Description
CAPABILITIES
- Wideband omnidirectional acoustic radiation for assessment of both airborne and structure-borne generated phenomena
- Accurate in situ measurement of output volume velocity using a pair of low-noise, ¼-inch microphones
- Dual-microphone design minimizes near-field effects of the test object for optimum measurement accuracy
- High-power output for measurement on vehicles with high transmission loss or when background noise conditions are sub-optimal
- Measurement of frequency response functions at vehicle source systems (engine bay, tyres etc.) with the use of a low-emission, 3-metre hose
- Quick-release coupling system for switching probes or hose-probe assemblies on the driver
- Microphones with CCLD and TEDS for quick setup
- Built-in overload protection circuit
- Can be used with BK Connect software for real-time volume velocity measurements:
- Use VVS Measurements Type 8442 for frequency response measurements related to a pass-by source path contribution model
- Use Data Processing Type 8403 for general NVH measurements
