Areas of intervention

The purpose of environmental acoustics is to guarantee sound protection for residents or residential areas located near business areas or technical equipment.

Acoustica intervenes in the management of noise linked to any activity and to the operation of technical equipment, and takes into account all the elements that structure our environment:

We intervene whatever your problem:

Installations classified for the protection of the environment.
Any equipment likely to generate noise pollution
Land, rail or air transport infrastructure.
Wind turbines.
Noise coming from spaces receiving public and broadcasting amplified music (gym, ballroom)

Our main fields of intervention in environmental acoustics:

<u>Areas conditions:</u>

  • Environmental measurements of the areas conditions: technical equipment, noisy activity, transport infrastructure.
  • Acoustic diagnosis and characterization of sources.
  • Expert reports with analysis of the situation in relation to the regulations in force.

<u>Forecast impact:</u>

  • Acoustic modeling.
  • Sizing of acoustic solutions.
  • Evaluation of the effectiveness of the proposed solutions.

Activities sectors

<u>Establishments receiving public and broadcasting amplified music</u>

  • Verification of the compliance of establishments receiving public and broadcasting amplified music according to the decrees in force.
  • Measurement of the residual noise level in the environment.
  • Measurement of the specific noise level, subject of the neighborhood complaint.
  • Assessment of the value of global and spectral emergence.
  • Numerical modeling of the propagation of acoustic waves.
  • Proposal of solutions to reduce the sound impact of noisy sources.
  • Evaluation of the effectiveness of the proposed solutions.

<u>Installations classified for the protection of the environment(cogeneration and trigeneration premises)</u>

  • Measurement of the residual noise level in the environment (before installation of the study premises).
  • 3D digital modeling of the site in its environment and the propagation of acoustic waves.
  • PProposal of solutions to reduce the noise impact of the classified installation.
  • Evaluation of the effectiveness of the proposed solutions and the compliance of the noise level after solution with respect to regulatory values.
  • Assistance with project management, work monitoring, reception.

<u>Equipment likely to generate noise pollution</u>

  • Measurement of the residual noise level in the environment.
  • Measurement of the specific noise level, subject of complaint from neighbors.
