Plan de acción contra el ruido de actividades de ocio al aire libre

In certain environments it is not possible to achieve compliance with the external noise levels. In such cases, however, normative stresses the compliance levels in the interior of the housing. The communication presents a study of the possible actions in a recreation area consisting of a set of open doors music bars which gives as a result loud street levels. The first step is creating a detailed sound map of the environment through simulation, in which the sources of noise are the openings in the facades of these bars. The second step is to determine the acoustic sound insulation of the receivers’ facades. Known the relationship between interior level of each activity, the level on the facade of the receptors and considering the acoustic insulation, the solution consists of reducing the level of noise emission of the activities and/or increase the isolation of the affected homes. Through the use of GIS, the level inside of the receivers and the affected population is also calculated. These variables along with the cost associated with the necessary increase insulation in facade, defines a mathematical model that allows to optimize the combination of acoustic insulation and reducing the noise emission of the activities.
