Abstract
This COST Action has been focused on the acoustics and low frequency vibration of timber based lightweight buildings, for which methods for predicting and measuring performances, as well as methods for assessing comfort and acoustically designing buildings are not as well developed as for heavy building. Airborne and impact sound performances, and sound from service equipment have been considered over a frequency range including the low frequencies (50 to 100 Hz) where lightweight buildings are likely to have performances lower than in heavy buildings. Low frequency vibration (below 25 Hz) such as walking induced vibration of floors has also been considered, and particularly its subjective aspect.
