Abstract
Concentration of sources of noise and vibration into densely populated regions and into buildings of slender construction according to modern practice has shown the need for the introduction into civil engineering of definite methods of vibration damping. This is necessary in particular with prestressed concrete construction in which there is normally hardly any internal damping and the stronger the concrete the less the damping will be. The slender forms of construction and greater speed ranges of many machines leads to more chances of striking a condition of resonance in a vibrating structure, wherein the exciting forces will be opposed only by the damping forces. Too little damping will mean large amplitudes and much noise.Keywords
