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…
Use of the speech transmission Index for the assessment of sound annoyance in open-plan offices C.1/1.063/P2014-071 | 2014

In open-plan offices, employees often have to work despite being distracted by multiple sources of speech close to them. This disturbance is even more severe when the surrounding conversations are intelligible. For this reason the disruptive…
Reflected acoustic field above an aperiodic wall facing containing non-parallel cavities. ET2013-001/P2014-090 | 2014

The purpose of this study was to determine the acoustic pressure field above a grating of non-parallel rectangular cavities. The Kobayashi Potential (KP) method has been used. This method was originally developed to study the diffraction of electromagnetic…
Acoustic characterization of facings with periodic profiles used in industrial rooms C.1/1.046/4676/NS268 | 2007

Facings in industrial rooms can have periodic profiles. Various methods for the acoustic characterization of those kind of facings are presented in this work. The waveguides method, is well adapted to the geometries usually met in industrial…
Study of the acoustical diffusion above a cavity and a network of cavities. C.1/1.060/P2012-190/NS297 | 2012

The purpose of this research project was to develop a theoretical model dealing with reflection of acoustic waves over a grating of N rectangular cavities. Thus, the diffracted acoustic fields were determined by adapting the Kobayashi Potential…
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…
Acoustics of open-plan offices : a new french standard. NOETUDE/P2013-123 | 2014

Taking in to account noise disturbance within office space construction and planning is now a major objective for the experts who participate to international standardization groups. In 2012, the international standard ISO 3382-3, specifying…
Study of the influence of the type of sound sources on the annoyance and performance at work in open-plan offices. C.1/1.063/P2014-095 | 2014

More and more frequently used by the companies of the tertiary sector, the open-plan office is a type of work organization which both enables to increase the occupation density and facilitates the oral communication between colleagues. Nevertheless…
