NEW ENVIRONMENTAL NOISE MANAGEMENT CONCEPT
SOLVES INTEGRATION AND INTERACTION HEADACHES.
A modular environmental noise management solution has been
developed by Bruel & Kjaer to address current as well as future
noise mapping needs and action plans.
The new Bruel & Kjaer Noise Management Concept simplifies the
management of environmental noise by efficient handling of the interaction
between measured and calculated environmental noise results.
The new Noise Management Concept system is suitable for handling
multiple clients and areas as well as dealing with smaller semi-permanent
tasks. The new product has been developed to optimise the data
exchange between different users, consultants and clients. The systems
new environmental noise calculation software, monitoring and measuring
equipment combine to implement 1st maps, develop action plans and
provide data to the public as well as regulatory organisations such as
the European Environment Agency.
The new systems development is the result of a major customer research
project aimed at providing solutions to address the requirements of the
EU Environmental Noise Directive 2002/49/EC. The Bruel & Kjaer Noise
Management Concept offers an integrated approach to environmental
noise management that make all tasks and activities more effective.
Environmental noise calculation and mapping software is combined with
monitoring and measurement equipment in a single, cost effective,
integrated noise management system. A key element is Bruel & Kjaers
Noise Management Software Type 7843A installed on a Noise
Management Server Type 3642. The softwares modern architecture
provides a versatile platform to handle proposed future noise management
The systems hardware also features a Bruel & Kjaer Noise Monitoring
Terminal Plus Type 3639-E, which is a powerful, modular noise monitoring
terminal that can be used in all environments and conditions. Featuring
a specially designed enclosure the terminal can be left unattended as
part of an environmental noise monitoring system for permanent, mobile
or semi-permanent monitoring.
Alternatively the terminal can also be controlled by a remote PC using a
The Type 3639-E has a dynamic range of 110dB and provides the ability
to log several parameters down to 0.5s periods. Remote verification of
the entire measurement chain is achievable using the patented Charge
Injection Calibration check (CIC). The terminal comes with a selection
of options such as sound recording, weather-data monitoring and
1/3-octave real time analyses.
The Noise Management Concept system comes equipped with a Bruel
& Kjaer Type 4952 Outdoor Microphone that is guaranteed for unattended
outdoor use with no significant change in sensitivity for a year. The
microphone functions correctly under conditions of up to 96 percent
relative humidity and in ambient temperatures ranging from -30 to 55ºC.
Construction is simple and features a protective anti-bird spike.
The experience gained from four decades of continuous research and
development has been used to develop the Bruel & Kjaer Noise
Management Concept, explained Jong-Bo Kim, Bruel & Kjaer UKs
internal sales manager. Now we can give you all the data you need
and only the data you need to control the environmental noise.
The integrated environmental noise management system can cover
complaints, mapping, monitoring, calculations and abatement. The
system will also provide reports, public information and safe, intuitive
archival of data, results, reports and analyses.
