 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.
