NEW LONG-TERM ENVIRONMENTAL NOISE MONITORING
SOFTWARE IS IDEAL FOR WORKPLACE NOISE ASSESSMENTS.
New Enhanced Logging software for the long term monitoring
of broadband and spectrum data is now available to support
Bruel & Kjaer s innovative Type 2250 fourth generation hand-held
The new BZ7225 software is ideal for implementing noise profiling
investigations as well as providing continuous monitoring and logging
of Periodic Reports for the development of time histories used in
environmental noise and workplace noise assessment studies.
The software allows free selection of parameters to log at periods
from 1 second to 24 hours. All broadband parameters can be logged
by running the Enhanced Logging software in conjunction with Bruel
& Kjaer s Sound Level Meter software (BZ7222). The spectra can
also be logged at the same rates by enabling Bruel & Kjaer's
Frequency Analysis software. To address the requirements of US
and EU regulations the new Enhanced Logging software module
calculates the Ldn, Lden, Lday, Levening and Lnight parameters.
In the event of a power failure during the continuous monitoring
process the Enhanced Logging software automatically reboots
and resumes operation. Data is saved in manageable portions
(every 24 hours) selectable for download. The user-friendly
software also allows operators to easily browse between markers
(like sound recordings).
As a noise monitoring platform, the Type 2250 instrument allows
different combinations of application software modules to be
selected. Additional applications such as Frequency Analysis
(BZ7223), Sound Recording (BZ7226) and Logging software
(BZ7224) can be purchased when needed and are delivered
as easily installed licences, explains JongBo Kim, Bruel & Kjaer's
internal sales manager. In this way a customer s investment in
the Type 2250 platform is securely protected and when their
measurement and analysis requirements grow then the Type
2250 can readily accommodate them. Bruel & Kjaer is committed
to maintaining an ever-growing range of applications on this
