Form follows function — and in this case, performance
Noise doesn’t travel in straight lines — it expands, reflects, bends, and diffracts. That’s why geometry matters in noise abatement.
At CALMA-TEC, we realized this early. Our first barrier design bent outward — away from the source — to reduce the angle of noise diffraction and deepen the “shadow zone” behind the wall. The result? A significantly higher shielding effect than traditional straight barriers of the same height.
This idea became a signature — and ultimately, the foundation for PIN.
What does PIN’s shape actually do?
PIN is not just a block of absorbing material. It’s an aerodynamically optimized element with a curved profile that strategically alters how sound travels over the barrier. Here’s how:
- 📐 It changes the angle of diffraction, reducing how far sound travels beyond the wall
- 🧊 It breaks up wave energy, acting like a turbulence fin
- 🔇 It pushes the noise shadow deeper, meaning better protection just behind the wall
- 🌀 It combines geometry + absorption, which leads to exponential effectiveness
In other words: it’s not just the material — it’s the shape that multiplies the effect.
Small element. Big impact.
Thanks to its unique geometry, a 50 cm PIN element can match or exceed the shielding performance of a 1.5 meter conventional wall extension — all without additional construction height, foundations, or engineering work.
That means: more performance with less material, lower visual impact, and smarter use of space.
Good design is invisible — but measurable
Every curve in PIN was engineered with purpose. And the results are not just theoretical:
- 📊 Up to 6 dB improvement in shielding
- 📏 Equivalent to +1 meter wall height with just 0.5 m PIN
- 🔧 Seamlessly integrates with existing wall types
