Before he work as a Technical Consultant in Stp, he is a experts in Car Audio System, he won alot of champions in EMMA, ISACA international competition.




Mr.Dmitry said : If you wan to get maximum effect use complex of suitable materials for each surface and follow " Applications instructions. Acoustic Materials" . Different materials are different effective.

3 catagories of soundproof :

a) Vibrations Damping Materials
