A1/3 - SOUNDEX® Pyla-Tech® Attenuator

A patented product that was designed specifically for piling within the rail industry and its unique design helps to reduce the noise that emanates out of the steel cylindrical piles during impact.

The design incorporates extra strong magnets which hold the attenuator to the pile during each impact. In addition to the magnets each individual attenuator is secured together with a Velcro connection removing the requirement of extra straps or buckles. With each unit only being 500mm long it is possible to remove them in sections as the pile is driven into the ground enabling maximum attenuation throughout the piling process. The remarkably simple system contributes significantly in reducing the noise pollution whilst remaining practical, functional and retaining the visibility required during the piling process.
