Barrier performance
Investigate the reduction achieved by the barrier arrangement, with source conditions, receiver positions and site limitations documented.
Noise control / field verification
Noise barrier testing in Malaysia.
Assess the acoustic performance of road, rail and temporary noise barriers. S&V Teknik brings field measurement and noise-control engineering together to help project teams evaluate the installed system.
Discuss barrier testing
The question behind the test
What do you need to verify?
Sound transmission
Discuss in-situ airborne sound insulation testing where the specified method and site access permit an appropriate assessment.
Before and after
Compare baseline and post-installation noise measurements, accounting for changes in activity, traffic and measurement conditions.
A complete installation
Panel ratings are only part of the picture.
A barrier’s performance at a receiver depends on its height, length, position and continuity. Ground gaps, open joints, gates and sound travelling around the ends can influence the measured result.
Our assessment starts with the engineering question: are you evaluating the barrier itself, investigating a weak point, or checking noise at a nearby property? These require different measurement arrangements.
From site brief to findings
A clear testing scope.
Plan the assessment
Review drawings, source activity, receiver locations, access arrangements and the project’s test requirements.
Measure on site
Record the agreed acoustic measurements together with instrumentation checks, site observations and operating conditions.
Report and interpret
Present the agreed results, test arrangement and limitations, with practical recommendations where investigation identifies concerns.
Engineering experience
Road and rail noise-control projects.
S&V’s company profile documents acoustic testing at SUKE and LRT3, alongside its noise barrier and enclosure work on major Malaysian infrastructure projects.
Explore the project portfolio for the scope and quantities recorded for MRT SBK, MRT SSP, DASH, SUKE and LRT3, delivered in collaboration with Muhibbah Engineering Bhd.

Questions before testing
Noise barrier testing FAQ.
Is insertion loss the same as sound insulation?
No. Insertion loss describes a change in sound level associated with introducing a barrier under a defined comparison. Sound insulation concerns sound transmitted through the barrier. They answer different questions and should not be used interchangeably.
Can temporary barriers be assessed?
Yes. We can discuss baseline and post-installation measurements or monitoring for a temporary arrangement. The assessment scope depends on the source, operating schedule, receiver positions and access.
Does a test automatically establish compliance?
The result must be assessed against the agreed project criterion and a suitable test method. A panel rating or a simple before-and-after level difference does not establish site compliance on its own.
What should we send for a testing quotation?
Include the site location, barrier drawings or photographs, dimensions, source type, operating hours, proposed test requirement and available access windows.
