Mobility Testing

In mobility testing, accelerance, mobility and compliance functions are calculated. For structures with well-separated modes, estimation of natural frequencies and damping ratios is possible. Often done during troubleshooting using hammer testing.

FOR ACOUSTIC HOLOGRAPHY

The capabilities of our noise source location software, Acoustic Holography Type 8607, can be extended with these optional additions. They all use a hand-held probe with two layers of microphones in conjunction with a positioning system that locates the probe in relation to the object under test.

Wideband Holography BZ-5644 is our patented calculation method that allows a single measurement at an intermediate distance to cover the combined frequency ranges of statistically optimized nearfield acoustic holography (SONAH) and beamforming – extending the higher frequency limit of holography
Proximal Holography BZ-5963 enables conformal noise‐mapping of transient events to create animated, 3D noise maps on a 3D model of the test object, using Brüel & Kjær’s equivalent source method (ESM) algorithm
Panel Contribution BZ-5640 quantifies the contributions to the total sound pressure level at the driver's ear from the various surfaces inside a vehicle, using a volume velocity source to establish the frequency response functions
Intensity Component Analysis BZ-5641 gives better understanding of the sound field inside cabins and other enclosed spaces, using a volume velocity source and operational measurements to map front source intensity, rear source intensity, scattered intensity, radiated intensity
In Situ Absorption BZ-5642 helps to map acoustical absorption of various panels to optimize interior trim and detect acoustic leaks
