FOR GOOD MEASURE

SAVE TIME AT EVERY STAGE FROM MEASUREMENTTHROUGH TO REPORT

Taking accurate acoustic measurements is critical – but not everything. You also need to efficiently document and report on what you’re doing to finish a project.

Introducing the new Measurement Partner, a suite of innovative solutions that supports customers through every step of the measurement process. Take remote measurements with its Wi-Fi-enabled sound level meters so sound fields aren’t disturbed. Efficiently make integrated annotations with its smartphone field app. And automatically upload data to the cloud to immediately begin using its post-processing software. Completing the solution are a resource-rich learning centre and an online community with blog posts and discussion forums.

For sound control,

it’s best to do things by the book.

Until now, it hasn’t been easy to make sure your building complies with all the Australian and New Zealand standards for acoustic control.

That is why Rondo commissioned acoustic experts, Norman Disney & Young Acoustic Services to advise, monitor and analyse an extensive programme of airborne sound and impact insulation tests.

Testing was carried out at the laboratories of the University of Auckland, New Zealand, and CSIRO at Highett, Victoria.

The result is our Acoustic Wall & Ceiling Systems Manual that shows, for the first time, how our systems comply with all relevant codes and will help acoustic consultants and engineers to design

their next project with confidence.

To find out more, and to see the results of those tests, visit www.rondo.com.au/acoustic and download the book now.
