THE update of the map of noises from the city of Cordobawhich was examined yesterday by the Local Government Council, highlights that some 46,000 neighbors of capital they have a issue at night at an acoustic level with the traffic. Of course, the work, dated September, shows a significant progress compared to the previous map of the issue, the development of which began in 2016.
The document states that “the main source of noise observed in the city is the road traffic» Industrial and railway activities are also analyzed. As for road traffic, the results during the day and in the afternoon are positive. In daybelieves that the 95.1% of the population -303,858 inhabitants of the capital out of a total of 319,627- is below 65 decibels (dB) and for the evening period, 98% of residents (313,368) do not exceed the aforementioned noise level.
This means that a a large part of the population This fulfilling THE goals acoustic quality for residential areas.
These levels are not reached when we observe what is happening at night. There, the number of Cordobans affected by noise is increasing. 85.6% of the population is below 55 decibels – logically, the bar at this time of day is lowered. This last indicator implies that the 14.4% remaining exceeds this threshold. That’s to say, 45,982 Cordovan suffer from a problem noise by road traffic.
95% of the capital’s residents during the day do not suffer from noise pollution from traffic.
And within the latter, we distinguish two large groups. On the one hand, 40,141 live together with an acoustic level of traffic noise between 55 and 60 decibels. 5,814 others suffer from it in a range from 60 to 65. Finally, 27 residents of the city suffer from a noise level of 65 to 70.
The document, prepared by the company Acusttel (Acoustics and Telecommunications), recalls that after the detailed analysis of the sources of noise pollution, it is “the urban traffic the one who generates largest population affected“. In road traffic, this document continues, “the most significant conflicts in terms of noise levels are generated by the main arteries”. In the current situation, “traffic management is the most effective tool for setting improvement goals”.
Updated capital’s noise map indicates ‘main source’ of noise pollution is road traffic
Of course, the map itself shows progress. In the previous edition -began to to be developed in 2016-, the card detected that there was a 46.8% of the population -153,863 citizens- who were affected by the noise of the traffic at nightby exceeding the aforementioned 55 decibels. In other words, the group that suffers from noise pollution at dusk due to this problem has decreased by more than 32 points.
Inside previous studyFurthermore, in the period dayA 77.7% was on the threshold Acoustic quality objectives have been achieved. NOWthis group goes to the one mentioned 95.1% -they are 17.4 points more-. In the afternoon section, on the still valid map, 79.40% did not have noise problems with traffic. This group now progresses by 18.6 points.
Rail traffic
When the document passed yesterday by the Local Government Council analyzes the noise pollution which generates the rail traffic warns that there is “a very low percentage of affected population» for her.
Train stop in Villarrubia
The noise due to this type of transport impacts “a very localized area from the capital, precisely near the medium and long distance railways, in the areas of Villarrubia, El Higuerón, Las Quemadas and in part of the urban area of Córdoba. The work reminds us that “part of the rail traffic is underground when it crosses the urban area” of our city.
Noise problems from trains are residual and no noise pollution linked to industrial activity has been detected.
The map indicates that currently, in the daytime, 99.8% of the population -319,023 Cordobans out of the 319,627 already mentioned- are below 65 decibels, which means meet acoustic quality objectives for residential area. In the evening, the indicator is practically identical: 99.9% of residents have no problem with railway noise. And during the night period, this percentage rises to 99.5%, the threshold then being 55 decibels. The indicators are very similar to those in the previous map.
Industrial activity
The last noise pollution factor analyzed in this study is that of industrial activity. The book states that the data indicates that the manufacturing sector “not a main source of noise» in Cordoba. And the results indicate that one hundred percent of the population is, in all three time zones, within sound levels meeting acoustic quality objectives. In the previous edition of this work, the number of people involved was really minimal.
However, the Acusttel document makes a punctuation: “It may happen that, in certain particular cases, in certain residential areas adjacent to industrial zones, disturbances are caused by the operation and activity of production facilities, which can only be quantified by measurement campaigns of the noise on site’.
total noise
After having separately addressed the sources of noise pollution, Acusttel analyzes the result of all of these sources in what is called “total noise“. These are indicators very marked by the impact of traffic.
Among the quality objectives in this area are: 94.8% of Cordobans during the day and 97.8% in the evening.
Inside at nightthis percentage falls to 85%. In other words, 15% of registered people (47,873) suffer from 55 decibels or more.
Again, if you look back, the the improvement is more than noticeable. On the previous map, 48% of the population (157,679) suffered from noise problems at sunset.
The text brings together measures it came take possession of the town hall in this area. It should be taken into account that the first sound map of the capital was approved in 2009.
They are indicated as actions “already applied” to combat it. regulation of nightlife; paving on urban roads; the reorganization of traffic and mobility, including pedestrianization – we remember the intervention on Cruz Conde -; the actions of the Local Police, control; or the public transport model, which affects the use of private vehicles.
