The procedure uses the blocked force of the source as input data. This quantity can be determined using the reception plate method according to EN 15657:2017. The methods have been developed and validated for stationary excitation signals (Leq). Real structure-borne sound sources often have time-varying excitation signals. In addition, the requirements for sound insulation against noise from building service equipment in Germany (DIN 4109) are given in terms of the maximum, time-weighted sound pressure level (LFmax). This contribution investigates the suitability of the methods described in EN 12354-5 and EN 15657 for structure-borne sound sources with transient excitation signals. A measurement series with time signals ranging from stationary to highly transient was conducted in a building-like laboratory. The reverberation time of the receiving room was adjusted to three different values. The calculations were processed using Leq values, LFmax values and short-time Leq values. The results show the uncertainties that can arise in the prediction of signals with varying transient characteristics compared to stationary excitation signals.}, language = {en} } @inproceedings{HoellerZeitlerReinholdetal., author = {H{\"o}ller, Christoph and Zeitler, Berndt and Reinhold, Steffi and Jakob, A. and Hopkins, C.}, title = {Charakterisierung von K{\"o}rperschallquellen auf der Empfangsplatte mit Hilfe von orthogonalen Funktionen}, series = {Tagungsband - DAGA 2019 : 45.
