April 27th is World Noise Reduction Day. One area in which noise plays a measurable role is urban planning. So urban architecture is designed for this purpose in times of increasingly densely populated cities.

It’s a fillet piece: with a view of the Kiel Fjord in its soft mirror and central location. If only the property and the amazing new building weren’t confined to the streets small and big! “The so-called KoolKiel Building is a mixed hotel and residential building. We have a high level of traffic noise and commercial exposure here. Here is a KVG warehouse, where buses run in the morning and evening and where you have a high level of noise or emissions,” says Klaus-Peter Jol. He talks about a demonstration urban development project in Kiel. A man from the Environmental Protection Agency accompanies her for a long time. It is slated to be an 18-storey building with a heavily vaulted glass facade and Rubik’s Cube aesthetics. The design comes from the office of a famous architect in Rotterdam – it would be really stylish if it weren’t for the constant noise from nearby city dwellers, bus depot and pool with nearby parking spaces.

“If you look at the overall noise, we know from the study that we can easily get into the area that poses a health risk – at least in terms of healthcare. That’s why we have to respond. We give the planners or investors something that helps them make sure that you can survive In your living room or bedroom even with the window open,” Jules says.

Soundproof glass facade against city noise

We are in the Klaus-Peter Juhl office in the city center. There are maps with glowing red traffic noise in Kiel. Two screens show the KoolKiel Tower in all its color and conspicuous beauty: the broken facade allows for balconies and terraces. It is difficult to distinguish between the inside and the outside. Remarkable is the glazed loggias. ‘The glass can be pushed to the side so that you can use the outside area as you like – for sunbathing or similar things. Otherwise sunbathing is not possible like that. Then you have traffic or other noise directly in the bedroom or in the living room. There is an option to protect the spaces With blinds-type glazing, which means you have a glass facade about 50 cm in front of the window that acts as sound insulation.This dramatically improves noise protection, says Henning Busch of the acoustics office of the same name in Casual.

The “Urban District”: Enabling Living and Working Together

Busch is currently planning to use these impact discs in the Mühlen district of Bad Kleinen: “It’s further away and not as urban as the project in Kiel,” he says. “It’s a former mill complex that was used to deliver and process grain. I think the grain came by train. There is now a former granary that is not presentable.” Gray is like the German Democratic Republic, but soon became the nucleus of a new vibrant region on Lake Schwerin. The thing is next to the wide train tracks, which seems like a lot of noise. Back in the day, an old mill lurks and open greenery can be seen. “You can probably imagine that if you’re upstairs, you have a nice view of the lake on one side. But on the other side there’s a lot of noise. It might not be that great of the view either. Now that has to be revived, and there’s an idea if the possibilities are The metropolitan area “can help here,” says Henning Busch.

Here, too, homes should be baffled. Henning Busch also shows porous stone – a soundproofing material for the facade, which does well with glass in front of it and air in between. He says the term “urban area” is important. It is fairly new and makes it possible to live in a noisy setting. The people there are protected in such a way that they can live and work side by side.

Compromises and Mutual Considerations

The acoustics engineer puts plans for another quarter on the table. In the urban area of ​​Elmshorn, there is a redevelopment area where the old facilities of the Kibek Carpet Factory used to be. “This is a huge expanse, a big skyscraper,” says Henning Busch. “It has been repurposed as a public housing area and there are areas adjacent to other industrial facilities. Housing is definitely under pressure. An industrial facility that makes something that doesn’t stop day and night makes noise, but you can sort that out in a certain way that lowers the level. The ‘urban area’ creates opportunities there.”

All these processes gained real momentum only as a result of the long-standing desire to live in the city and its condensation. And even if many people think in the opposite direction because of Corona: without compromise, it is no longer possible in cities. “It is always a duty to show mutual interest,” says Henning Bosch. “It’s like living in an apartment building. I can’t expect to hear nothing from my neighbours. If a neighbor is partying, sometimes it’s loud at night. You can reduce that through structural measures that don’t run away.”

In the German Maritime Museum and in the Ozeaneum in Stralsund there is an “acoustic chair” that makes the sounds of the sea audible. more
