We fight the "reverberation noise" in order to make people in public buildings feel comfortable, allow a clear receipt of audition and messages transmitted through speakers at the same time protecting from noise.

Reverberation noise, an element which deteriorates acoustic conditions, is mentioned in the Interpretation Document to Directive 89/106 EEC concerning building products.

In this section we will present norms, directives and regulations for designers and architects, which concern protecting from noise - people, hotel guests, participants of sport matches and concert.

We will show the accurate sound techniques and industrial technologies, which decrease noise and the damage that it causes to human organism.

In Technology section we present innovations concerning the above techniques. Please place information about innovations, problems that occur in this field and solutions in our CHAT section.
