When trains reach 300 km/h, the noise barrier becomes part of the aerodynamic equation.
Conventional solutions often fail under the extreme forces of high-speed rail. At CALMA-TEC, we addressed this challenge many years ago — and developed a certified system that still performs today. This article explores what makes noise protection on high-speed tracks a discipline of its own.
Many existing noise barriers are too low by today’s standards. But rebuilding isn’t always the smartest option. With PIN, performance can be upgraded quickly and efficiently — without replacing the wall.
This post explores how and why it works.
In many infrastructure projects, noise protection is treated as an afterthought — with costly consequences. From vague tenders to real-life failures, this article explores why many noise barriers don't deliver what communities need — and what planners, clients, and local authorities can do differently.

Is your home louder than it should be?
Traffic, construction, city hum — noise creeps in and wears us down. But how loud is too loud? And what does that mean for your health?
Discover what decibels really mean, how constant noise affects your well-being, and how you can measure — and improve — the soundscape around you. Spoiler: it’s easier than you think, and the difference of just 3 dB might change your life.
👉 Read the full post and check out our decibel scale to see where you stand.
Noise pollution from roads and railways is a growing concern for urban areas, infrastructure planners, and communities worldwide. But what is the most effective way to reduce noise? The answer is simple: start where the noise is generated. Emission reduction — tackling noise at its source — provides the strongest and most lasting results.
Noise pollution is a growing concern in urban environments, highways, and railways. While traditional noise barriers have been used for decades, open absorber technology has long been overlooked despite its superior acoustic performance. The reason? Until recently, significant technical and material challenges prevented its widespread adoption.
In modern life, noise has become an unavoidable part of our daily environment. Whether it’s traffic on busy roads, passing trains, or industrial activity — noise pollution surrounds us. But it’s not just an inconvenience. Scientific research has shown that prolonged exposure to excessive noise poses a serious threat to human health and well-being.
