    <title language="eng">Experimental study on using transient excitation signals in the prediction of sound pressure levels from building services according to EN 12354-5 and EN 15657</title>
    <abstract language="eng">EN 12354-5:2023 describes a calculation procedure to predict the sound pressure levels from building service equipment. 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.</abstract>
