Industrial Acoustic


Underground Ventilation, Industrial Plants, Building and Residential, Public Use Endowments and passenger transport.

From the past to the present, it has meant progress in the industrial process to create a large number of «machines». The process of design and implementation of these machines, in most cases, excludes an acoustic point of view (studied by the Industrial Acoustics) which involves creating noisy and vibrating machines. The Acoustics Industrial is the discipline that tries to mitigate the effects of noise in the development of industrial activity.

An example of industrial progress is the development of transport (metro and railway lines mainly) that now constitute the main exponent of the noise and vibration that occur daily .

cabins or acoustic enclosures for generators, machine shields on deck, acoustic doors, circular and rectangular silencers for ventilation or extraction, visors, benches for engine rooms, etc … all these elements are used by the resources Industrial acoustic to reduce the harmful effects of noise and vibration.



This sector within the Acoustics Industrial application encompasses innumerable designs for infrastructure projects of public works, among others. The tunnels and galleries are focused today to save problems such as landforms, traffic areas collapsed, future pedestrian areas … and much solution and for which we must not forget the acoustic point of view . Therefore, they are elements that appear in projects:

  • Extension /Renewal of Metro lines
  • Extension /Renewal of railway lines (Cercanías, High Speed ​​…)
  • Extension /Renewal road (suburban tunnels, highways …)
  • Extension /Renewal of mining galleries



In the case of industrial plants, they usually consist of large complex divided into several buildings ordered by utilities. All these complexes are usually away from urban centers; however, there are usually both residential areas near industrial plants as environmental regulations that may limit the emission levels of noise allowed the complex. This is where the Acoustics Industrial should focus its efforts to resolve the noise problems resulting from industrial activity . Examples of some of these facilities are:

  • Electrical Substations
  • Plants Combined Cycle
  • treatment plants, desalination plants and sewage treatment plants
  • Steelworks
  • Paper industry
  • Making online



This sector includes the realization of projects for:

  • Hotels and Paradores
  • Residences, Hospitals and Health Centers
  • Schools
  • Official and Administration
  • Buildings

  • Offices and Homes



This sector includes the realization of projects for:

  • Supermarkets
  • Parkings
  • Transport exchangers
  • Shopping Centers



This sector includes the realization of projects for:

  • Cars /Tractor Metropolitan
  • Cars /Tractor train (high speed, commuter, InterCity …)


The facilities related to the various sectors of the Acoustics Industrial must consider a game of acoustics, coupled with ventilation systems. Thus, they contemplated solutions such as:

  • Silencers Acoustic circular for longitudinal fans
  • Mufflers rectangular Acoustic extraction /transverse air immission
  • absorbent Acoustical Treatments for intermediate ventilation rooms
  • Acoustic Doors Room for ventilation division
  • Treatments Acoustic absorbents for reducing levels of indoor reverberation.
  • Enclosures (fixed or self-supporting) and acoustic screens for deck machinery.
  • Benches of inertia for soportación machinery.
  • Acoustic treatment production lines.
  • Definition of acoustic exposure areas for operators.
  • Acoustic viewers to control dashboards.
  • Silencers Acoustical Duct for drives in rooms.
  • Vibration Systems to soportación machinery.
  • Acoustic doors of access to high-emission zones.
  • Acoustic absorbent treatments for engine rooms.
  • Paramentos (walls, floors, ceilings) floating for airborne sound insulation and impact.
  • antivibration systems for floors, trunks or ducts.
  • Design absorbent systems in pressure conduits.
  • Systems airborne sound insulation in cabin walls for centralized traction.
  • Systems airborne noise insulation in floors for distributed power.
  • Components silencers for HVAC system .
  • Acoustic measurements and noise footprints in the cabin and wagons.
