Environmental Acoustics

TRANSPORT

  • Acoustic environmental assessment of ports, airports. highways and rail lines (high speed, goods, tramcar, metro lines), on local, regional, national and international regulations.
  • Detailed measurements, analysis and identification of noise sources related to transportation.
  • Prediction of vibrations in structures, buildings and users.
  • Acoustic simulations to represent, in the form of noise maps, the noise generated by the infrastructures of transport.
  • Engineering design and technical specifications for noise and vibration control.

 

BACKGROUND NOISE

One critical aspect in any industrial project is to properly define the ambient noise level. It is required to define the baseline or the so-called "background noise" or "residual noise". In most of the cases, this factor will set the noise limits in a project. INERCO can provide guidance about interpretation of this phase of the project.

  • Measurements and analysis of background noise, baseline and residual noise in any kind of areas prior to the implementation of new activities.
  • Identification of noise sources and their contribution to the environmental noise level.
  • Noise maps representation using specialized software to perform acoustic simulations.

 

INDUSTRIAL AND COMMERCIAL

  • Measurements, analysis and detailed identification of noise and vibrations sources: machinery, factories, processes, building facilities (including HVAC)
  • Evaluation of compliance with environmental sound limits in local, regional and national regulations.
  • Advanced acoustic modeling of sound prediction and vibration models: insulation, absorption, emission and vibrations.
  • Design and preparation of technical specifications for noise and vibration control systems.
  • Turnkey project scope available for noise control systems.

 

BUILDING

  • On-site measurements and remote monitoring to verify compliance with regulatory sound limits in the construction phases of buildings and industrial plants.
  • Design and development of engineering technical specifications with temporary measures of noise and vibration control.

 

WIND FARMS

We are specialized in noise prediction at large wind and compliance assessment according to international systems and regulations:

  • Assessments of background noise and baseline prior to the implementation of wind turbines. Evaluation of the environmental acoustic impact of wind farms.
  • Acoustic modeling of the operation of wind turbines through advanced simulation techniques: prediction of noise levels according to the direction, speed and operating regime of the wind farm.
  • Continuous monitoring of wind farms: alarm systems in case of noise limits exceedance.
  • Minimization of disturbances of wind farms through wind turbine monitoring and modeling techniques.
  • Evaluation of facades and roofs insulation for buildings.

 

MINING

  • Assessments of background noise and baseline prior to the implementation of new mining operations. Evaluation of environmental acoustic impacts of mining facilities.

  • Characterization of Zone Acoustic Saturated (ZAS).
  • Execution of insulations and acoustic coatings as solutions to noise problems.

 

VIBRATIONS
