Field measurements of the Mobility and Vibrations induced by human walking on a wooden floor

• Lightweight constructions of timber material are cost effective and demands relatively short production duration. One of the main drawbacks of lightweight structures, however, is related to the sound transmission. More and more complains arise against this type of structures, related to the propagation of low frequency vibrations induced by human activities. Most problems are caused by human walking, more exactly foot impacts, which generate a harmonic force whose frequency is close to the natural frequency of the floor. This investigation is focused on measurements of induced walking vibrations with real human walking and the mobility; those were performed on an in-situ wooden floor. The measurements of accelerations induced by a walking person were used to evaluate existing vibration criteria.
