| Descripción: |
With the aim of reproducing in laboratory conditions the transmission process and the annoyance of a traffic noise through a regular housing facade sample with a window frame, the authors have used traffic noise records with different statistical distributions and electronic devices as compressor, dynamic range processor and spectrum shaper. These experiments, conducted with a constant equivalent level on frontage, have permitted to obtain the reactions of groups subjects with different noise level dynamic ranges and different opening conditions of the window. The effects of the slope of the transmission loss of the facade sample have also been studied with a constant internal equivalent level. The coherent results obtained on the scale of annoyance clearly indicate the weakness of the generalized use of Leq level for only one descriptor of the environment Le choix d'enregistrements de bruit routier de distributions statistiques différentes et l'utilisation d'un compresseur ou d'un expanseur, ont permis de recréer en Laboratoire diverses situations environnementales derrière un échantillon de façade. Lors de ces expériences, menées à niveau équivalent constant, ont été étudiées l'influence de la dynamique résultante dans un logement, suivant différentes conditions d'ouverture de la fenêtre, ainsi que celle de la pente de l'isolation procurée par l'échantillon de façade. Les résultats très cohérents obtenus pour les gênes exprimées par les participants montrent bien les faiblesses de l'emploi systématique du seul niveau Leq comme descripteur de l'environnement. |
