Noise monitoring software

New Enhanced Logging software for the long term monitoring of broadband and spectrum data is now available to support

Type 2250 fourth generation hand-held analyser.

The new BZ7225 software is reportedly 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 software also allows operators to easily browse between markers (like sound recordings).
