Building acoustics in Aix-en-Provence - ARKEMEP
Acoustic engineering guarantees the quality of use, regulatory compliance and acoustic comfort of buildings.
ARKEMEP is involved in acoustic design, modeling, simulation and optimization for all types of projects.
The regulatory acoustic measurements are carried out by ARKENOR, a specialized entity of the ARKORIS group.

Why is specific acoustic engineering necessary in Provence?
The Mediterranean climate and urban density significantly alter acoustic requirements:
- increased use of heat pumps and outdoor equipment,
- noisy urban or road environments,
- high standards of intelligibility in ERP systems,
- the need to limit reverberations in often open spaces.
Acoustic studies of the building (NFS 31-080)
We carry out complete acoustic engineering for commercial buildings, public access buildings and residential buildings:
- facade insulation,
- treatment of airborne and interior noise,
- equipment noises,
- shock level forecasts (target 55/58 dB),
- 3D modeling and reverberation calculations on empty shells.
Acoustic study of outdoor heat pump units and technical equipment
- sound propagation study
- AcousPropa simulation (GAMBA),
- 3D modeling of the project (worst-case scenario),
- definition of assumptions (walls, acoustic power),
- technical variants,
- indoor and outdoor noise maps.
➡️ Objective : to secure the installation of heat pumps and limit their noise impact.
Acoustic diagnostics and improvements to existing buildings
ARKEMEP carries out acoustic diagnostics on existing buildings, as part of renovations, compliance work or nuisance treatment.
These assessments help identify sources of non-compliance, define corrective solutions tailored to the constraints of the existing building, and verify acoustic performance after the work is completed. (Acoustic measurements in partnership with ARKENOR )
Acoustic engineering for rooms (lecture halls, meeting rooms, teaching spaces)
For each location, ARKEMEP models, simulates and optimizes:
- speech intelligibility (STI),
- the reverberation time Tr,
- spatial decay DL2,
- the target acoustic objectives.
- V0: initial state according to planned geometry and materials.
- V1 : proposal of absorbent treatments (wall panels, suspended ceiling…).
➡️ Deliverable: study report with comparison of scenarios.
Sound diffusion and sound system studies
We design sound diffusion engineering to guarantee consistent intelligibility:
- position and quantity of speakers,
- directivity and sound power,
- 3D acoustic modeling of the room,
- sound pressure level (Lp) maps,
- STI calculation with systems in operation.

Standard process of an acoustic study
ARKEMEP structures acoustic engineering in 6 steps:
- Defining objectives and collecting data,
- 3D acoustic modeling,
- simulations (levels, Tr, isolations),
- area-by-area analysis
- identification of discrepancies,
- suggestions for improvement & verification by simulation.
BIM & 3D acoustic modeling
Digital modeling facilitates acoustic coordination from the earliest stages:
- precise geometry
- realistic materials & features,
- reliable simulations,
- anticipation of non-conformities.
Mission phases and deliverables
ARKEMEP is involved from the preliminary design phase to the procurement phase:
- preliminary analyses,
- 3D modeling,
- variants & arbitrations,
- PC reports, DCE, Markets.
Acoustic characteristics in Provence
Projects subject to a Mediterranean climate include:
- intensive use of outdoor heat pumps,
- exposure to road or urban noise
- open buildings requiring Tr control,
- stringent requirements for ERPs.
➡️ Local engineering is essential to ensure lasting acoustic performance.
