AbstractA study carried out by the Building Performance Center (BPC) to examine sudden, high-level noise events in different types of new build dwellings is presented. The objective of the investigation was to record, quantify and if possible identify the source location of the noise events within the dwelling building fabric. The results of the measurements conducted indicate that the source of the 'noise events' is located in the gypsum board ceilings of each property. It appears there is a relationship between the stiffness of the plasterboards and a tension or compression action imposed on them by rapid changes in temperature, sudden pressure change or very slight dynamic movement, causing a noise event to occur. The noise event was reported as being associated with being sourced somewhere in the ceiling zone areas across a variety of room types.
