Validation of an Acoustic Model for Four Prototypes Sectors in Guayaquil City

Abstract:

The acoustic models and indicators of acceptability estimated and validated extended territorially the application of those determined in a first stage, which, evidenced that, the analysis of geo-territorial prototypes with appropriate methodologies, are pertinent to calculate the noise due to high traffic in Guayaquil. Currently, the slant to develop and applicate an acoustic ordering is based on analysis carried out for territories of small surface. A geoterritorial analysis expanded by more than 100% and the results validated the methodology and management of the variables investigated. With the analysis of more than 5000 new records, the modeling related the sound intensity, vehicular traffic, surveys and citizen perception for critical socioeconomic sectors. Statistical and probabilistic methods generated indicators with reliability between 78% to 98%, which validated the estimates in the two stages. The second stage allowed the models to be calibrated and validated and showed that the indicators can be extended to similar populations and territories with acoustic conflict.
