The legal regulator framework for industrial activities requires a suitable evaluation and a noise levels decrease in the working plants, outside as wel as inside (protection of workers against noise).
PREDICTIVE ENVIRONMENTAL IMPACT. ACOUSTICAL STUDY.
From the predictive analyse of the acoustical impact estimated in the current state of exploitation of the industrial activity, the future fulfillment of the legal limits established regarding to exterior acoustical pollution as well as, in case of no fulfillment, the possible corrective measures on the concrete noise sources, can be determined.
Through an analyse based on a acoustic prediction software, each noise source can be modelised and can be classified depending on its individual pollutant effect on a affected zone. This allows to calculate the resultant level with corrective treatment of one or various sources.

FIELD ENVIRONMENTAL IMPACT. ACOUSTICAL AUDIT.
In the currente state of exploitation of an industrial activity, a control of the acoustical pollution is necessary, in order to analyse the fulfillment of the legal limits. |
PERMANENT MONITORING
Permanent system of environmental noise measurement outside through an environmental station situed near form the industrial plant.
Through this system, the noise levels can be continuously monitorised during more than 24 h. Consequently, the noise evolution can be analysed in a determined area during a several days. |

RANDOM SAMPLING
This consists of a noise map around the industrial site, based on temporal measurements at different times, that allow to evaluate the noise produced by the operating activity and the background noise with the industry stopped. |
 |
CONTROL PROGRAMS INSIDE AND OUTSIDE THE INDUSTRY
Noise evaluations inside and outside the industries can conclude on the necessity of corrective measures in order to adapt the noise levels to reduce the explosure on workers and outside.
Through a noise control program, the acoustical problem can be globally analysed and sistematical and adequate solutions can be implanted with concrete noise reduction objectives for each action. This way the incertainties in the inversion can be eliminated and the solution implantation can be and coherently realised. |
