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.

Noise source identification

Noise Source Identification (NSI) is an essential tool to reduce noise, and to understand and optimize noise that cannot be eliminated. With Brüel & Kjær noise source identification equipment, acousticians can diagnose, visualize, understand and solve noise issues. By tracing noise back to very specific components, engineers can target their mitigation efforts more accurately.

Noise Source Identification (NSI)

After locating noise sources, acoustical hotspots and leaks using a variety of tools ranging from hydrophones to outdoor arrays of up to 144 channels, it is possible to identify and characterize the most important sub-sources.

Ranking these helps decide where mitigation strategies can most effectively reduce overall sound power radiation, or reduce certain noise components such as specific frequency content. Mitigating noise can be accomplished by reducing, damping, or decoupling noise sources from the overall structure.

Through the iterative use of NSI tools in the design and prototype phases of product development, the overall noise profile of the product can be optimized, thus ensuring proper compliance with given noise limits and regulations.
