Low Frequency Volume Velocity Source
LVVS | DIRECT VOLUME VELOCITY MEASUREMENT, 30HZ – 500HZ
The low frequency volume velocity source is an omni-directional sound source which behaves like a acoustic monopole with controlled source strength. The sound source has a particle velocity sensor mounted at the end of the duct to accurately measure its broadbanded acoustic output. The frequency range covered by this source goes from 30 Hz up to 500 Hz. A power amplifier is supplied with this volume velocity source.
FEATURES
- Frequency range 30 Hz – 500 Hz
- High power output: max. Sound Power of 122 dB
- Direct volume velocity measurement
- Integrated particle velocity sensor
- Fast reciprocal transfer function acquisition
APPLICATIONS
- Acoustic Transfer Functions
- Panel Noise Contribution Analysis
- Transfer path analysis
- Airborne source quantification
- Component vibroacoustic behavior characterization
This omni-directional noise source is equipped with a Microflown particle velocity sensor on the tip of its nozzle, being the only source capable of directly measuring the radiated volume velocity for a broad frequency range with unparalleled accuracy. The source is capable of generating high excitation levels in order to properly excite the sound field under study. This Low Frequency Volume Velocity Source can be used for a wide range of applications like transfer path analysis, component vibroacoustic behavior characterization, airborne source quantification and pass by noise simulations
