Our History

The Product Physics Experts

For many decades, HBM and Brüel & Kjær have been trusted by multiple industries to deliver highly accurate technologies and expertise in test and measurement.

Synonymous with innovation and quality, these two renowned and pioneering brands joined forces to become Hottinger Brüel & Kjær (HBK), forming the world’s foremost provider of integrated test, measurement, control, and simulation solutions for product performance evaluation.

HBK continues to build on the two legacies, untapping the potential of combined knowledge and insight within three physical domains – mechanical, sound and vibration and electrical – and allowing us to pursue solutions for the unmet needs of our customers.
