Noise is a kind of environmental pollution, that, like any pollutant agent, have harmful effects on health and causes, among other phenomena, auditive and psychological alterations.

Noise is one of the worst pollutant agent in our cities, the acoustical energy that affecs to the most developed countries has doubled in these last years and thus, a legislative framework has appeared at local as well as national and European level.

For example, the importance of environmental pollution by noise and vibrations is captured by the European Comission Green Book, in which the obligation to realise studies of environmental impact of public and private project is established in its annexe.

As a response to the legislative national or European framework, Acusttel offers solutions to public institutions, environmental auditors or private promotors needs in the field of pollution by noise and vibrations.

Acusttel, thanks to its technical and human capacity, realises:

PREDICTIVE ACOUSTICAL IMPACTS

It deals with the evaluation of the pre-operating acoustical outlook in a determined zone, due to the future influence of a noisy activity, a communication way, the modification or execution of an urbanistical plan, as well as the analyse of the compatibilities between urban zones and other kinds of area, or the problems due to changes in soil classification.

The environmental acoustical evaluation will be useful to realise a rational territory planification.

ACOUSTICAL IMPACT EVALUATIONS

In operating situations, it is necessary to evaluate the acoustical pollutant levels, in order to planify preventive measures or to solve a current noise problem.

The acoustical evaluation of an environmental noise problem requires an acoustical study, in which random estadistical measures and a permanent noise monitoring have to be performed, in order to analyse the time evolution of the noise levels.

The field evaluation of a noise pollutant problem will be useful, in the case of having to implant corrective measures, to modelise the acoustical features of each noise source, in order to, through predictive methods, propose the most adapted corrective measures for each concrete case.

CARTES DE BRUIT

Les cartes de bruit ont pour but d'analyser les niveaux de bruit existents sur un territoire communal et informer sur les sources sonores causes de la contamination acoustique, dans la mesure où différentes études sont réalisées le long des principales voies de communication, zones industrielles et de loisir, zones résidentielles et commerciales, zones spécialement protégées et centres historiques.

PLANS ACOUSTIQUES MUNICIPAUX

Les cartes de bruit constituent la première étape nécessaire vers la réalisation d'un plan acoustique municipal, avec l'identification des zones acoustiques existentes, pour de cette manière adopter les mesures préventives et de régulation qui permettront la réduction progressive des nivaux sonores.
