PreNoise® allows users to predict noise levels of service equipment in buildings, based on the standards of EN 12354-5. It provides an early-stage approximation of the planned object and allows users to quickly select suitable systems with the required noise protection level in the planning phase and helps to assess the impact of changes to the building's structure. PreNoise® is developed by...

The calculation method to predict noise from building service equipment according to EN 12354-5 has seen significant improvements and gained acceptance in recent years. In some countries (e.g. Germany), it is also finding its way into national building regulations as a means to show compliance with requirements. Still, there is more research needed for the prediction of noise from building...

EN 12354-5 describes methods for predicting noise from technical equipment based on both airborne and structure-borne sound emissions. With respect to structure-borne sound, laboratory methods for source characterisation are specified in EN 15657, providing the necessary input data for prediction models.In particular, for timber constructions, a complete characterisation of the source,...

Prediction of structure-borne sound from building service equipment (BSE) in heavyweight buildings, as outlined in EN 12354-5, requires knowledge of the normalized impact sound pressure level of floors or walls that the BSE is connected to. Standard tapping machine measurements provide a straightforward method of obtaining this quantity for floors, but are not applicable to walls. For such...

Structure-borne transfer functions enable the analysis of the frequency-dependent transfer behaviour of linear, time-invariant structures. While complex narrowband transfer functions are typically evaluated to assess specific system properties, building acoustics classically describes the behaviour of components using spectra in one-third-octave bands and spatial averaging. For structure-borne...

Noise from building service equipment is often neither ideally stationary nor ideally impulsive, but exhibits a complex temporal structure. Requirements for sound insulation against noise from building service equipment in Germany are given in terms of LAF,max,n. This raises the question of how such noise should be treated in the prediction method according to EN 12354-5 and EN 15657, which is...

Compromises among cost efficiency, sustainability, and occupant comfort require efficient prediction concepts in building acoustics. For structure-borne sound problems, the driving-point mobility at the excitation position is a key quantity for estimating the power introduced into the structure by the excitation source.Previous studies have shown that approximating the driving-point mobility...

Sanitary installations are among the most disruptive sources of noise in buildings. At the same time, they are some of the most complex examples of building service equipment since they usually consist of several active and passive components such as toilets, washbasins, taps, valves, pipes and pipe clamps etc. and complex interactions. To design systems that meet target values given as...

As high-density residential living becomes a global trend, managing bathroom drainage noise from prevalent under-slab piping is vital for indoor acoustic comfort. This study investigates the noise reduction effects of various drainage pipe materials and structural acoustic claddings to mitigate noise at the source. To evaluate performance efficiently during development, a simplified laboratory...

Drainpipe noise can be a prominent annoyance and privacy problem in modern housing. Heavy pipe systems with low vibration mobility are standard practice for achieving acoustic comfort in solid construction buildings. However, it is not clear whether the vibro‑acoustic performance of the pipe systems in massive constructions can be transferred to lightweight construction. This study examines...

Structure‑borne sound generated by wastewater pipesystems often dominates noise emissions from sanitaryinstallations in buildings. This noise is mainly caused byturbulent annular flow and by water impacts on inlets, tees,and bends. The water excitation, and thus the resultingstructural response, is treated as a stochastic process anddescribed by its power spectral density (PSD). A...
