Acoustics_UrbanPlanning

__** Big Cities **__ have an acoustic problem. The buzz of urban life is often perceived as deafening noise which makes people ill.

__** these are some of these problems: **__

__Road traffic__ is the main noise in the big city. The sound of the engines, the roar of the exhausts, braking and the horns are a rumbling background in which we are accustomed to live.

The __roar of the planes__, __the railway__, surface and subway, and the __industry__.

__Public works__. The excavators, trucks, compressors and welding equipment.

__Recreation, the disco and bar__. Not only because of local noise, but by the movement of people, the noise of vehicles and motorcycles. Young people drinking in the street and put their music. Football stadiums, playgrounds, celebrations of festivals and fairs, musical performances on the streets, fireworks.

__Public services__, police sirens, ambulances and firefighter’s vehicle cleaning, trash removal.

After all this connection, it should not surprise us that our life has elapsed wrapped in noise, especially if you live or work in a big city.

**__The urban planner solutions__** to address the problem of noise are as speed restrictions for noise abatement measures. Even in the rare cases where the urban planners have coordinated their efforts, the focus is still on quantitative aspects, such as reducing noise levels, rather than on qualitative criteria.
