CALMA-TEC PIN Lärmspoiler®
Existing noise protection systems can be retrofitted effectively and cost-effectively with the CALMA-TEC PIN Lärmspoiler®. This has a height of 50 cm and corresponds in effect to a conventional increase of a noise barrier of 1.5m. The high degree of efficiency eanables lower construction heights of the noise barriers.
The CALMA-TEC PIN-Lärmspoiler® provides up to 18 dB reduction in sound pressure. The increased effect is achieved by the patented upper edge of the wall and the specially foamed polyethylene whisper foam. Mounted on a two-meter-high wall, the PIN Lärmspioler® ensures a 30% reduction in percieved noise; this corresponds to halving the volume of traffic.
