Soundblox acoustic concrete blocks

We have come to appreciate "quiet" moments more and more in our hectic modern society, which is often too noisy and busy. The ASONA company has designed the Soundblox, with a view to creating more peace and quiet in many of these noisy, busy places.

his concrete block for facing brickwork is produced by Gubbels under licence from the ASONA company. The concrete block has two vertical slots opening out into a hollow space. This space and the slots together form what is called a ‘Helmholz resonator’, which absorbs a substantial amount of the sound energy hitting the block. Soundblox walls have been used throughout Europe and in a variety of applications for many years now, and have proven themselves as the reference system in the field of sound absorption.
