Acoustic correction of classrooms, meeting rooms and reception rooms. Following an experimental evaluation of the acoustic comfort, SONORHC can propose specific corrections to be carried out to make the room adapted to the use, a follow-up of work is also possible.
Design of music schools. The simultaneous practice of different music courses requires the creation of rooms with optimal conditions. The problem is twofold: on the one hand, the rooms must be isolated from each other to ensure sufficient discretion, and on the other hand, each room must be treated to obtain reverberation conditions adapted to the musical practice considered (singing, percussion, piano, etc.).
Acoustic insulation between rooms. The treatment of the separating partitions makes it possible to limit the transmission of the sound between two rooms, either by improving the existing one (doubling) or by creating a new phonically insulated room in a noisy place (command post in a workshop for example).
Machine noise measurement, intensimetry and noise emission reduction. It is a question of measuring the noise emitted by a machine in order to detect the zones of sound emission in order to implement solutions of reduction of the noise nuisance. In addition to a classical pressure measurement, SONORHC has developed a know-how based on the measurement and analysis of the acoustic intensity, giving precise information on the areas to be treated.
Virtual reality for audio. Classical sound reinforcement is often based on old stereophonic concepts. The 3D Audio, called ambisonics, uses spatialization tools developed for a totally immersive acoustic experience.
SONORHC now has its own ambisonic recording and replay system, which can be used to create "soundscapes", acoustic sculptures, augmented reality, or spatialized concert broadcasts.
Measurement of noise in the environment, reduction of acoustic impact. Each industrial, commercial or residential installation is subject to regulations concerning its acoustic emergence. SONORHC can establish measurements in order to verify the conformity of the installations, and propose solutions for improvement in case of exceeding the threshold.
Acoustic impact study by Code Tympan. This code from computation, produced by EDF and made available to users as an open source, allows the prediction of noise resulting from the construction of an installation at the preliminary design stage, but also the simulation of the effect of different noise reduction techniques such as acoustic screens. It is possible to work on the optimal implementation of the installation, the installation of protections or the reduction of noise at the source.
Reception of wind farms. These installations are subject to acceptance and are the subject of a complex acoustic study depending on the wind conditions. SONORHC has the technical and material means to estimate the acoustic impact of such installations.
