Temporary noise barriers
For construction phases, roadworks, demolition, industrial shutdowns and changing source locations.
- Modular and reusable
- Rapidly reconfigured
- Rigid panels or acoustic curtains
The engineering principle
A barrier works by changing how sound reaches the receiver.
A noise barrier interrupts direct line of sight and forces sound to travel over or around an obstacle. The resulting path difference, frequency content and source-to-barrier-to-receiver geometry influence the insertion loss that can be achieved.
Panel surface density matters, but continuity is equally important. Gaps at the ground, open gates, short returns and barrier ends can create flanking paths that reduce overall performance. S&V Teknik considers the whole installation rather than treating the panel rating as a site result.
Choose by application
Temporary or permanent?
The correct system depends on programme, exposure, available footprint, structural design and the required service life.
Permanent noise barriers
For roads, rail, fixed plant, industrial boundaries and developments needing durable long-term mitigation.
- Site-specific structural design
- Durability and maintenance planning
- Acoustic and visual integration
Design variables
Six details that change the result.
Height
Controls the path over the barrier crest.
Length & returns
Limit sound travelling around barrier ends.
Continuity
Ground seals and closed joints reduce leakage.
Proximity
Placement close to the source can improve screening.
Absorption
Useful where reflections between surfaces matter.
Structure
Wind, foundations, access and safety remain essential.
Noise barrier FAQ
What project teams usually ask.
How much noise reduction will a barrier provide?
There is no responsible single figure without geometry and source data. Performance depends on height, length, gaps, frequency, ground profile and source-receiver positions. Measurement and modelling can establish a project-specific expectation.
Should the barrier be absorptive or reflective?
Reflective systems can be suitable in open layouts. Absorptive faces may be preferable where reflected sound could affect the opposite side, parallel façades or nearby equipment. The site arrangement should guide the choice.
Can a noise barrier solve low-frequency noise?
Low-frequency sound diffracts more readily and can be harder to control with a barrier alone. Source enclosure, silencers, isolation or operational controls may need to be combined with screening.
