By combining this data with the mobility of receiver structures it is theoretically possible to predict the sound pressure level in a building. In a case study of a washing machine on a wooden joist floor this prediction process was investigated. The prediction was based on the normal force component only. The contact area at the feet of the washing machine was made as small as possible to avoid the influence of moments while the in-plane components were assumed negligible. These conditions proved to allow for accurate predictions in the coupled state in a previous publication [1]. The results show that the prediction from independently measured normal source and receiver quantities yields large errors below 125 Hz as a consequence of the above assumption. Between 125 and 900 Hz the error of the prediction is within ± 5 dB. The case study further investigated two assumptions frequently encountered in practice: low and high-mobility sources and no cross-coupling between the feet}, language = {en} }
