Commissioning verdicts guide
Loopworks™ is a ground-breaking hearing loop test and
measurement system
Loopworks Measure app takes you
through the steps required to perform
a commissioning test. All of your test
results for each section are recorded at
multiple positions across the room.
Each test clearly shows a pass, qualied
pass or fail verdict live on screen.
Results are collated within the app to
give a simple overall verdict against
relevant performance standards.
Knowing how verdicts are measured will
give you the best chance of achieving
a pass when commissioning your next
hearing loop system.
Overleaf is a handy guide to
commissioning test verdicts from our
Loopworks measure app.

Overall verdicts:
Pass = all sections are passes, will still pass if overspill and venue accessibility have no verdict.
Qualied pass = one or two sections are qualied passes, can still qualied pass if live listening, overspill and venue accessibility have no verdict.
Fail = any section is failed or three or more sections are qualied passes.
*
Selecting Australian standards, with metal present for the commissioning session, will increase eld strength qualied pass window for area coverage
systems to -9dB to +6dB.
