CONTENTS INTRODUCTION
INTRODUCTION
Innovative Solutions
At Brüel & Kjær we have always set standards – from the first range of
measurement microphones to the first multi-analyzer, the first real-time
acoustic holography system and the first battery-powered sound intensity
analyzer. The technical developments have been driven by close collabo-
ration with our customers. We focus on our customers’ needs to supply
the whole measurement chain – from a single transducer to complete
turnkey systems. We maintain alliances with suppliers that enable us
to deliver newer and more efficient ways for our customers to improve
their products’ quality and stay competitive. Technology has no limits –
if our customers can imagine it, we will strive to develop it.
Top Quality
In all aspects of sound and vibration there are challenges to be met.
For example, ensuring that the car, bus or train for your daily commute
can withstand the mechanical shocks it will experience demands meas-
urements of great accuracy and precision. This requires instruments with
the performance and quality to match. All our products are thoroughly
tested, often in the harshest environmental conditions. Extremely high
standards are met in all aspects of product and service provision, as
reflected in our status as an ISO 9001 certified company.
Thanks to their reliability, quality and robustness, our products usually
come with a service period of at least 5 years after the end of production.
This ensures that customer needs continue to be met. The same concept
applies to legislation. This often means documented results that are
traceable to established references, such as a national calibration labo-
ratory. Brüel & Kjær service centres offer all the support required.
Training Courses
Educating and training customers is part of the Brüel & Kjær tradition.
We focus on educating and equipping the course participants with
the necessary sound and vibration knowledge and skills. Our global
educational programme offers modular courses and training that cover
theory, applications and instrumentation.
WE OFFER:– Training courses at locations near the customer – Experienced instructors from our company – Latest high-quality training materials – In-house courses for larger numbers of participants

A modern, cost-effective noise monitoring and management solution
for a wide range of applications, technologies and budgets. Noise
Sentinel is a subscription-based service that takes care of noise, vibra-
tion, dust and air quality monitoring in real-time. Brüel & Kjær handles
installation, calibration and maintenance, and you receive daily reports
via email or alerts on your mobile or other specified destinations. With
Noise Sentinel, we take care of monitoring and managing your environ-
mental levels so you can be sure you are in compliance with regula-
tions, leaving your to focus on other tasks. You can manage real-time
noise issues and share noise compliance information on the Web.
The environmental noise management service Noise Sentinel

Portable Noise Monitor Terminals Type 3655 showcase our wide range
of innovative instrumentation for environmental noise monitoring and
management.
Short-term noise monitoring
Noise Sentinel – On Demand is short-term, unattended noise monitor-
ing that fits the needs of noise consultants and public authorities
During monitoring, you can view noise data in real time wherever you
are, and receive immediate SMS alerts if noise levels approach compli-
ance limits. You can regularly review the high-resolution data online,
to investigate the noise picture and maintain an overview. It helps you
warn clients of danger levels, review data with them, or send them
regular reports that are automatically produced.
After monitoring is complete, you simply return the equipment and we
securely host your data for as long as you need, making it easy to find,
easy to share and accessible anywhere.
Your data remain available for review, download and further analysis.
There is a small subscription fee based on the amount of data stored.
