Sound Insulation of Multi-Storey Houses — A Summary of Finnish Impact Sound Insulation Results
Building Acoustics, 2000Evidently a wooden house can be built so that modern requirements for both airborne and impact sound insulation are met with sufficient margins. However, low-frequency impact sounds produced by walking may be either audible to the building occupants or felt by them as non-audible vibrations.

The report offers a survey on the sound insulation indices that are most widely used in building acoustics. Analyzed are also the procedures of obtaining the indices, especially the ISO 717 reference curve system in comparison with the direct calculation of the sound reduction by the dB(A)-method. On the basis of references, the two methods are seen to

Bench Studies of Sound Insulation Materials and Vacuum Sound Insulation Panel
Material and Mechanical Engineering TechnologyThere is a problem of protection from high-level sound of city residents, employees of enterprises; to a greater extent, in the workshops of machine-building factories, for example, during stamping, forging and other metalworking processes. Specialists and maintenance personnel are exposed to high-intensity noise near powerful agitators, pumps, engines
