At the bicycle exist the bell is the loudest


Cities are loud. Every five years, a city has to record and publish the noise pollution. This is what Stuttgart has done for 2017.


Incidentally, noise costs money, all of us and the city. The bike is undeniably the quietest means of transport. It faces this tremendous noise level as a silent alternative. It is cheap to buy, fun and makes the city society healthier.



Electric cars are not always the solution. They may be quiet in the city, but on highways they are not. Because the main highway noise is the tire noise, which also makes an electric car. For residents near the highway so would change by an electric car traffic nothing.

There are always suggestions to move the traffic in tunnels (the photo shows the Heslacher tunnel). This means a little relief for the district, but generates more traffic elsewhere and a new noise pollution. Even in Heslach, which should be relieved by this tunnel, still revolves a lot of traffic. In addition, tunneling is extremely expensive. It would be cheaper to reduce the traffic in the inner cities as a whole and to put more emphasis on the extremely quiet cycling. That means making it so comfortable and safe that the sixty percent who do not dare so far, but are interested in getting on a bike, feel like doing so.

(According to the Institute for Innovative Cities, the Target Group for Cycling Promotion consists of 2 percent Fearless, 5 percent habit-driving, 60 percent interested and 33 percent non-cyclists.)



The noise pollution is not measured by the way, but calculated according to EU specifications with a key. And indeed from the average traffic during the day and at night. The noise level is calculated for the height of the first floor (4 meters above ground level). On the first floor it can be even louder. And always it means, peak noise levels are not recorded. (Graphics: see below.) The individual Poser / Raser, whistling up the Stuttgart slopes between midnight and half past one and trying to create a sonic boom with the help of the engine, is not recorded there either. Harmful are noise levels above 65 decibels. A normal residential area has levels between 35 and 45 dB. *

All motorized transport make noise, the car most, but the trains, S-Bahn and light rail are just not quiet.

Of a continuous noise level of more than 55 decibels per day and over 50 dB at night, about 180,000 people are affected in Stuttgart. In a level range between 65 and 80 dB, there are still about 30,000 people living, mainly on Cannstatter Strasse, on Hauptstätterstraße, close to the motorway and the Autobahn. By night, only about 2,300 people are still affected by a Lämrpegel about 70 dB. This means high levels of stress for the body and a significantly higher risk of heart attacks *. In the east of Stuttgart live the most affected by noise, followed west and south. These are densely populated neighborhoods.



Noise is also an economic factor: sustained noise levels of more than 60 dB, which are common on major roads, lead in the long run to high blood pressure and more heart infections, but also to sleep disorders. This results in medical expenses (paid by the community of health insured persons) as well as accidents resulting from bad sleep and loss of production because those affected are sick. But even the city itself loses money, namely income from rental income, land transfer tax, property tax. And these costs are not borne by the noise source, so not by the car drivers, not even on the very small vehicle tax).


Noise costs us all that we live in Stuttgart right money.
According to the noise mapping report, the noise-related health costs in Stuttgart amount to around 17 million per year, of which 13.5 million are car traffic, just over 2 million rail traffic and 1.4 million light rail.

This does not include the costs of reduced productivity, death or the intangible value of loss of well-being.

In addition there are the costs for real estate value losses. According to studies, a landlord loses just under one percent of the rent per dB as soon as the continuous noise level exceeds 50 dB.



Addendum: With Tempo 30 at night you could help many people. The local council has requested a report on which roads could lead to a reassurance. CDU in the local council, parts of the FDP, free voters, the ultra right and the cityist, Schertlen, reject the report. Because this is so, the report could not be decided in the responsible committee UTA and had to be voted in plenary session of the municipal council.



* Federal Environmental Agency: "Health consequences of increased noise Noise triggers different reactions depending on the time of day (day / night) Generally speaking, at averaging levels within dwellings below 25 dB (A) at night and below 35 dB (A) during the day, These conditions are still met with tilted windows when the outdoor noise levels are below 40 dB (A) at night and below 50 dB (A) during the daytime, while at daytime average levels above 55 dB (A) are increasingly present outside the home In order to protect health, an averaging level of 65 dB (A) during the day and 55 dB (A) during the night should not be exceeded.
