The modelling of desk screens by a combined BEM – Source image approach. C.1/1.063/P2015-102 | 2015

An original BEM approach is proposed to study the efficiency of desk screens in open plan offices. For large offices the volume geometry can be approximated by two horizontal planes – for floor and ceiling – and the source image approach is used to…
Report on the "NOMAD" project. A survey of instructions supplied with machinery with respect to noise and the requirements of the Machinery Directive. NOETUDE/P2012-159/NS296 | 2012

The NOMAD project was a survey to examine the noise-related content of instructions supplied with machinery offered for purchase in the European Economic Area (EEA). The project collected more than 1,500 sets of instructions from machines covering…
Methods for the evaluation of warning sounds perception: the influence of hearing impairment and hearing protector EL2012-014/P2014-086 | 2014

In noisy industrial workplaces, the perception of warning sounds is crucial to ensure the safety of the workers. On the ground, the perception of warning sounds not only depends on the levels and spectra of the warning signal and of the ambient noise…
A survey of instructions supplied with machinery with respect to noise and the requirements of the Machinery Directive. NOETUDE/P2013-042/ND 2371 | 2013

A survey gathered the contributions of 14 European countries and was initiated by the “ADCO Machinery” group through the NOMAD project (Noise Machine Directive). The survey aimed to analyze the noise content information (emission level, risk management…
Validation and limitations of a device for measuring the sound scattering coefficient of walls facings present in workshop. ET2013-001/P2016-048 | 2016

The relief of wall facings present in workshops induces the scattered propagating waves. Predictive acoustic software for mapping the acoustic pressure field at workplace uses the acoustic characteristics such as absorption or diffusion…
Effect of noise on comfort in open-plan offices: application of an assessment questionnaire. C.1/1.063/P2015-106 | 2016

Open-plan offices account for 60% of French office workspaces. The noise levels recorded in this type of environment are much lower than those encountered in industrial workplaces. Nevertheless, surveys show that noise is considered by employees…
Numerical simulation method of sound propagation in enclosed spaces with non-flat walls. ET2013-001/P2016-045 | 2016

Accurate calculation of acoustic pressure field in enclosed spaces by room acoustic software is one of the main research concerns in room acoustics. Therefore, many numerical simulation methods have been developed, but even the most recent…
Physically-based numerical sound propagation modeling in rooms with non-flat walls. ET2013-001/P2016-115 | 2016

Nowadays, accurate sound propagation modeling is one of the main research axes in room acoustics. Many numerical methods exist, each with their own benefits. Nevertheless, compromises in terms of accuracy, size of the studied domain or frequency…
Sub-critical vibrating structures: on algorithm to speed up calculation of the acoustic radiated field NOETUDE/4630/NS264 | 2007

The Boundary Element Method (BEM) allows the calculation of the acoustic field emitted by a structure from its wall / panel surface velocity. This method requires a surface mesh whose number of nodes N increases with the maximum analytical frequency…
Prediction of open plan office acoustics. C.1/1.063/P2014-156 | 2014

Open plan office users complain of two annoyances due to noise. The first annoyance is lack of concentration and the second annoyance is the reduction of the confidentiality of conversations. The rapid prediction of the acoustic work environment…
