MORALES PEREZ, Javier  and  FERNANDEZ GOMEZ, Jaime. DISCRIMINANT ANALYSIS OF SOME VARIABLES THAT IMPACT ACOUSTIC CONTAMINATION CAUSED BY URBAN TRAFFIC IN A BIG CITY. Rev. ing. univ. Medellín [online]. 2012, vol.11, n.21, pp.13-22. ISSN 1692-3324.

Noise caused by traffic is the result of several variables; ones inherent to features of roads and the environment it crosses, and some others inherent to vehicles. From all variables which could cause this kind of noise, only few of them have been studied in depth intended to understand its real relationship to acoustic contamination. The level of sound pressure (Leq.) is the index used for evaluating acoustic contamination and the unit of measure is the decibel. This research involves measurement of all variables present in a big city which could have an impact on acoustic contamination, as well as the level of noise in Madrid City. All this conducted through a field work where 519 places were randomly measured and all this data were recorded

Keywords : Leq; noise; vehicles; variables; model.
