Customer driven

Our most important skill is listening – listening to the challenges customers meet in their work processes where increasing functional demands, time pressure, regulatory requirements and budget constraints mean that getting it right the first time is becoming ever more critical. Listening hard is our way of understanding customer needs and is the start of the road to finding long-term solutions to customer's sound and vibration challenges. The only way we can put our highly skilled force of engineers and our time-tested, market-leading product portfolio to work is by listening.

The sound and vibration challenges facing our customers are diverse - from traffic or airport noise, vibration in a car engine, evaluation of building acoustics, cabin comfort in a passenger airplane to production quality control or wind turbine noise. Over the years, we have developed creative and technically advanced solutions to innumerable customer problems. Some of the work we have done with customers is published as case studies.

Brüel & Kjær is founded on good ideas, hard work and entrepreneurship, and it is the passion for innovation and high quality that drives the company forward. 

Over 100 creative and dedicated development engineers at Brüel and Kjær are involved in research and development. New products and solutions are often conceived in cooperation with customers. We even have a team solely dedicated to creating new, groundbreaking technologies and products while actively collaborating with customers and academic partners.

For us innovation means:

  • Scientific and technological development - for example the groundbreaking surface microphone, the unique REq-X and Dyn-X technologies for PULSE, the world's first multi-field microphone, and LAN-XI - the market's only completely modular data acquisition system.
  • Creative employees - constantly involved in expanding our patent portfolio
  • Customer cooperation - to develop customised systems and solutions to specific challenges. Many of our standard products started with a customer challenge. We often involve customers in the R&D process to ensure that the features and priorities in  development projects meet customer needs. For example, this has been the case for the Sound Level Meter Type 2250, PULSE Reflex software and the LAN-XI data acquisition front-end system. 

By investing in a Brüel & Kjær solution, our customers invest in original research, real invention, a global network of expertise, and local support.


For nearly 70 years, Brüel & Kjær has been playing a leading role in the world of sound and vibration, by producing precision instrumentation for acoustic and vibration measurement, and by contributing heavily to the development of acoustic and vibration sciences themselves. Many of our employees are world-renowned experts in their respective fields and are often asked to speak at seminars and conferences, and advise on new standards. But our expertise doesn't only come from within our organisation; it also comes from working closely together with customers and partners to help solve problems.

Pioneers and innovators
Innovation has always been the core of our business. We’re proud of this tradition and continue to develop and face the challenges posed by our customers.

From the world's first charge accelerometer to innovative solutions and advanced analyzer systems - Brüel & Kjær has been a part of the development from the very beginning.

Environmental Noise and Vibration
Environmental noise is unwanted sound and vibration from a plethora of sources, among them industrial plants, road and rail traffic, construction work, and aircraft.

Add to these sports events, shooting ranges, leisure parks, etc, and you have noise from many different sources, each with different characteristics and posing specific problems for the professionals who have to assess them. The way the problems are dealt with differs immensely from country to country and is very much dependent on culture, economy and politics. We offer solutions to cover all demands from level checks to in-depth analysis, from measurement or prediction, to post-processing and reporting.

Occupational Health
Occupational Safety and Health is a major concern throughout the world. Problems such as a broken limb, the loss of an eye or persistent backache have to be dealt with and measures taken to minimise the risk of these things happening at the workplace.

However, it comes as a surprise to many that loss of hearing caused by noise at the workplace is second only to the broad category 'disorders of the locomotor system' on the list of occupational diseases. Millions of people suffer from noise induced hearing loss (NIHL), resulting in a reduced quality of life.

Hearing conservation programs are implemented in most countries and governed by international and national standards and legislation. Any such program involves an assessment of the noise problem, noise control and noise reduction measures. Important aspects of hearing conservation programs are the management of data, reporting of progress and the retrieval of data, for example, when claims are made.
