Resumen de Evaluation of acoustic properties of floating floors and materials used under floating floors for approval and certification aims: classification of stiffness and impact sound reduction applied in Poland
Marianna Mirowska, Pawel Tomczyk
In the paper, problems of evaluation of acoustic properties of floating floor products for purpose of approval and certification are discussed. The principles of determining the declared (required) values of dynamic stiffness s' of building materials and impact sound reduction level ?Lw of floor coverings are presented. Stiffness and impact sound reduction classes used in Poland for assessment of floating floor products are given.
