On this page we describe the main features of the optional BZ 7228 Sound Insulation Software. This is just one of the noise insulation systems we stock, see the complete Sound Insulation Equipment Range.
A single-channel building acoustics application module for Sound Level Meters Types 2250 that enables assessment of airborne, facade and impact sound insulation in buildings, according to a wide range of national and international standards.
The application module can be set up to guide the user through all necessary measurements (levels and reverberation time) at various points in source and receiver rooms. Measurements are controlled manually, and the built-in noise generator is automatically controlled. Sound insulation is calculated in situ and results are then displayed on the instrument.Uses
Facade Sound insulation
Complete hand-held building acoustics analyser
Measures source and receiving room level spectra, L1 and L2 (equalised)
Measures reverberation time spectra, T2 Impulse and Interrupted noise method
Calculates final results on the spot ISO plus 12 national standards
Measurement quality indicators
Colour touch screen user interface
Sound recording, voice commentary to document test environment
Analysis and report generation using the 7830 Qualifier, PC software
Complete systems available including airborne and impact sound sources
Measurement position guidance
Measurement position guidance is invaluable during the measurement process, particularly where more than one sound source position is used. Using the large touch-sensitive display, it is easy to prepare the sequence and monitor the progress of the measurement.
Trust your measurements
A 'smiley face' quality indicator shows the integrity of the measurements at a glance, and suggests how best to improve them – both overall and in detail.
Reuse your data and save time
Copy measurement data between projects and tasks, saving considerable on-site time whenever measurement data is common to different tasks. For example, you can reuse receiver room reverberation time for an airborne and an impact test on the same floor section.
Results in situ
BZ-7228 calculates building acoustics results in situ and presents interactive graphical and numerical data, meaning you can check your results make sense before you pack your equipment and return to the office.
