Building acoustics

Building acoustics issues

Controlled acoustics help to limit noise pollution, improve the quality of use of spaces and ensure the peace and quiet of neighbors. The problems encountered range from sound transmission between premises to noise generated by technical equipment, from the propagation of noise to the exterior to the internal acoustic behavior of volumes.
Building acoustics engineering aims to integrate these issues right from the design phase, in order to avoid non-conformities, costly rework and situations of discomfort for users.

A powerful diagnostic tool for industrial sites

SIM Engineering uses acoustic imaging to analyze industrial sites, technical installations and noisy equipment. Measurements can be carried out remotely, up to 300 meters away, without requiring direct access to the sources.
This capability makes it possible to intervene in areas that are difficult to access during normal operation, while guaranteeing the safety of those involved and continuity of operation. Acoustic imaging is thus an effective solution for rapid diagnosis and targeted expertise.

Eco-design and certification

In addition to indoor comfort, SIM Engineering also assesses the environmental impact of noise pollution generated by buildings, particularly that associated with technical equipment or the broadcasting of amplified music. The studies include :

• l’identification of the applicable regulatory framework
  
• visit regulatory acoustic measurement campaigns
  
• visit characterization of ambient and residual noise
  
• l’comparative analysis of regulatory thresholds
  
• the regulatory return and associated recommendations
  

These initiatives are in line with the objectives of sustainable development and the preservation of neighborhood tranquility.

Acoustic studies

SIM Engineering is involved in all aspects of building acoustics, including :

• visit façade insulation against external noise
  
• visit airborne sound insulation and impact sound insulation between rooms
  
• visit noise levels of technical equipment (HVAC, pumps, chillers)
  
• visit internal acoustic studies reverberation time, clarity, intelligibility, musicality, echo treatment
  
• the sound diffusion systems
  
• visit acoustic impact studies in the vicinity
  
• visit vibration impact studies
  
• visit ventilation and smoke extraction systems
  

These studies enable us to guarantee acoustic performance consistent with actual building use.

Building acoustics – Project management assistance (AMO)

SIM Engineering supports local authorities and project owners from the earliest stages of a project, to ensure that technical and regulatory choices are secure. Services include :

• the initial acoustic diagnosis of the project
  
• visit definition of acoustic objectives and expected performance levels
  
• drawing up technical recommendations,
  
• visit drafting acoustic specifications
  
• l’assistance with consultation and selection of service providers
  
• visit site supervision and final performance control
  

This mission enables us to integrate acoustics as a genuine design tool.

Building acoustics – Acoustic engineering studies

As part of its project management services, SIM Engineering carries out comprehensive acoustic studies to translate project objectives into concrete technical solutions. Actions include :

• the acoustic diagnosis and feasibility studies
  
• the acoustic design and modelling of buildings
  
• visit definition of compliant technical solutions
  
• visit drawing up technical documents and specifications
  
• visit site supervision and performance validation
  

This approach ensures consistency between architectural design, technical constraints and acoustic requirements.

Corrective studies and compliance

SIM Engineering also works on existing buildings facing acoustic problems: insulation defects, equipment nuisance, interior discomfort or regulatory non-compliance.

Corrective studies enable us to identify the precise causes of disorders and propose targeted solutions, whether they involve internal acoustic treatments, insulation improvements or modifications to technical installations.
