Trittschall — Entstehung und Dämmung

Methods for the characterisation of impact sound. Behaviour of different types of ceilings (homogeneous massive ceilings, hollow ceilings, double-layer ceilings) with reference to the underlying physical principles.

Isolation by floating floors, discussing the different possibilities of transmission and the significant parameters (stiffness of the isolating layer and of the enclosed air, flow resistance of the layer).

Reduction of impact sound by elastic floor coverings and discussion of the corresponding measuring parameters (mass of the hammer and shape of the striking surface).
