Six decades of innovative solutions for Noise & Vibration testing

Brüel & Kjær has the world’s most comprehensive range of noise and vibration test and measurement solutions.

We provide complete measurement and analysis systems, ranging from specialist transducers, through multichannel data acquisition, to workflow- and task-oriented application software and final documentation and reporting. Together with LDS’ comprehensive range of shakers & controllers we can furthermore offer complete shock and vibration test systems for durability and reliability testing.

Our extensive range of solutions are segmented into 4 Test Suites – the Acoustic, Rotating, Structural & Environmental Test Suites.

Acoustic Test Suite

Comprehensive range of data acquisition and analysis solutions for combating exterior or interior noise problems - optimising noise performance, improving noise quality and ensuring compliance with environmental legislation.

• Noise source mapping and location
• Wind-tunnel and flight testing
• Engine and aircraft noise certification
• Acoustic material testing
• Cabin comfort and occupational health
• Ramp noise and sonic boom testing
• Underwater acoustics
• Surface/underwater acoustic ranging and self-noise monitoring

Rotating Test Suite

Vibration analysis of rotating machinery provides valuable information on engine health, reliability and performance. Ranging from test-cell applications to on-ground maintenance systems, our vibration measurement and analysis solutions can provide you with powerful machine analysis tools.

• Vibration analysis, monitoring and diagnostics
• Vibration data acquisition and analysis in engine test cells
• On-ground vibration check of aircraft engines
• Order analysis and autotracking
• Balancing and trim balancing
• HUMS transducers

Structural Test Suite

Structural dynamics testing is essential to understand and optimise the inherent dynamic properties of structures to ensure reliable and safe operation. Our structural test suite offers complete solutions for controlled excitation test, real-life operational test and test-FEA integration - from the smallest components to the largest assembled structures.

• Operating deflection shapes analysis
• Operational modal analysis
• Classical modal analysis
• Normal mode testing
• Structural dynamics modifications
• Model correlation and updating

Environmental Test Suite

Reproducing realistic operational conditions in the laboratory is a must for qualifying the real-life integrity of structures to ensure durability. Whether it be billion dollar satellites, launchers, aircraft, instruments or structures our comprehensive test suite can provide you with a wealth of environmental test solutions.

• Sine, random, sine on random, random on random testing
• Classical shock
• Shock response spectrum
• Kurtosis
• Acoustic fatigue
• Field data replication
• Wave recording
