The BZ 7224 Logging Software is included and enables logging of broadband parameters and statistics for different periods. The optional BZ 7225 Enhanced Logging Software also logs spectra at these intervals using the included BZ 7223 Frequency Analysis Software.
In addition to Logging at 1 second to 24 hours and 100 ms periods, data can be logged at report intervals e.g. every hour, and for a full day. During measurements, markers and annotations can be added to the profile. With the Sound Recording enabled, WAV-recordings may also be used to capture events.Uses
Environmental noise monitoring
Occupational health assessment
Time history of events
Time history profiles for what-if scenario modelling
Logging of Broadband parameters, Statistics and spectra
Four different logging periods in parallel
All or selected parameters for full day, report and 1s - 24h period
Two profile displays: total measurement and zoomed time window
Spectrum and broadband real-time views
Markers and annotations on profile display
Attachment of Wav-recordings to profile
Create hour reports straight from the measured data.
Comprehensive data collection
Collect a wealth of broadband, statistic and spectral data, giving you the details behind the numbers and allowing for very flexible post-processing.
Grasp the essence quickly
Supporting up to five user-defined markers that can be set automatically (using trigger conditions) or manually (on the touch screen or using push buttons), it is easy during post-processing to locate noisy parts and unusual profile sections, and evaluate their significance.
Record sound events
With Signal Recording Option BZ-7226 enabled, wave-recordings of the measured noise can be added to the profile for documentation purposes, as well as subsequent event and source identification.
Freeze the display
At any time during the measurement you can 'freeze' the profile display, or move to an earlier section, allowing you to look at data in detail and add annotations while the measurement is still continuing.
