Port Noise Barriers: Quay, Yard and Gate Control
Ports are usually treated as an industrial cousin of the highway noise problem, and that assumption produces barriers which meet a specification and then fail on site. A port does not generate one moving line source travelling at speed. It generates a dozen unrelated sources, most of them statio...Read more -
Metal vs Transparent Noise Barriers: Which to Specify for Highway & Rail Projects?
On most projects the question arrives late. The alignment is fixed, the receivers have been counted, and someone asks which panel to write into the specification. The answer is rarely “metal” or “transparent” in the abstract. It is the noise barrier that satisfies the con...Read more -
7 Reasons a Sound Barrier May Not Cut Traffic Noise
A sound barrier is one of the few measures that reduces road traffic noise at the receiver without changing the vehicles or the road surface, and where it is sized and sited well it does the job. When it does not, the cause is usually one of a small number of predictable mistakes, most of them m...Read more -
Indonesia Highway Development: Noise Control Guide
Indonesia Highway Development: A Noise Control Guide Indonesia highway construction has become one of the largest infrastructure programmes in Southeast Asia, and it is now entering the phase where building the road is only half the job. Once a toll road opens, the sections that pass close to hou...Read more -
What Material Is Best for a Highway Noise Barrier?
It is the question every project engineer asks first: what material is best for a highway noise barrier? The honest answer is that no single material is best for every site. The right highway noise barrier material follows from the acoustic target, the structure that has to carry it, the environ...Read more -
Noise Barrier Foundation: Design, Types & Installation
Noise Barrier Foundation: Design, Types and Installation A noise barrier foundation is the least visible part of any acoustic barrier, and the part most likely to decide whether the wall still stands straight after fifteen years of wind, frost and traffic vibration. Panels and posts are what the ...Read more -
Transparent Noise Barrier: Acrylic vs PC vs Glass
When a highway, viaduct or rail project has to reduce noise without walling off the view, a transparent noise barrier is usually what the community and the authority ask for. The harder question comes next: which transparent material should be specified? Acrylic, polycarbonate and glass all deliv...Read more -
Metal vs Concrete Noise Barrier: Which to Choose?
When a highway authority or contractor evaluates roadside noise control, the metal vs concrete noise barrier decision is often the initial fork in the road. Both systems have decades of service history, and both can meet insertion-loss targets when correctly specified. But they behave very diffe...Read more -
Noise Barrier Sound Absorption: Testing, Ratings, and On-Site Verification for Highway Applications
Noise barrier sound absorption is the property that determines whether a highway sound barrier simply blocks noise or actually manages it. A non-absorptive barrier reflects sound energy back across the roadway, where it bounces between opposing walls or escapes to sensitive receptors on the oppo...Read more -
Noise Barrier Posts: Hot-Dip Galvanized Steel Structural Guide
Among all materials used for highway noise barrier posts, hot-dip galvanized steel is the clear industry standard — and for good reason. Galvanized steel noise barrier posts deliver the structural strength, corrosion resistance, and service life that highway projects demand, at a cost that no al...Read more -
Noise Barrier Sound Absorption: A Highway Guide to Absorptive Panel Systems
On modern highways, noise barrier sound absorption is no longer optional — it is an acoustic necessity. When sound barriers line both sides of a carriageway, reflected noise can bounce repeatedly between parallel walls, creating a “sound canyon” that erodes the noise reduction each ...Read more -
