NOISE

Eerlier design

In my Master 1 Urbanism trajectory I have made a plan for Almere-Hout. For this project I took noise into consideration. Especially the noise cause by traffic from the highway was very important in this design project. The location of Almere-Hout is situated between two Highways the A6 from Lelystad to Amsterdam and the A27 from Almere to Utrecht. These two highways are two main noise source for this location. When planning suburbs we need to take into consideration that the suburbs cannot be too close to the highways. In this case it is not only a noise problem but also an air pollution problem. Below some picture of the Almere-Hout project. In fig.1 you can see that the suburbs are situated like at least a 350 meters away from the highways. In the north part of the master plan I introduced a small forest to keep the noise away.
fig.1 Masterplan for Almere-Hout for Master1 Urbanism, to the North we see the A6 and to the East we see the A27


fig.2 on this perspective we can see the A27 above, the first row of building are industry and offices that will function as an sound barrier, the building area after the industry is down town and the building area infront of the picture is an suburb area that will not have problem with the noise and air pollution cause by the highway.
 

Future Design

Beside traffic, we know other types of noise. For example noise cause by aviation activities or noise provided by a city center or public facilities. Also industry has a great part in creating noise in the city. For the future design we as architects and urban planners need to keep consider noise as a very important element in the design process. To go back at some other subjects, winds can carry noise very far. It is not always guarantee that we would not suffer from noise in a city or town. People who are living some 10 to 20 kilometers from an open air festival center or sport stadium can have problems with noise when a event is taking place. Of course this is depend of the wind that will carry the sounds for kilometers away. Another element we can combine with noise is plantation. In the future we can consider plantation as natural noise or sound barrier in the cities.

In order for us to have some idea what type of noise a highway is creating and what is acceptable or not the Territory course provide the excel program to calculate the type of noise traffic and other sources are producing.
