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

ENVIRONMENTAL NOISE MANAGEMENT SOLUTIONS NOISE SENTINEL

Permanent noise monitoring

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

Type 7871, the Permanent Noise Monitor Terminals Type 3639 or the

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.
