Are you able to make changes to the flat ?

One very good way reduce noise from the street is to replace the windows with new windows with 2 or 3 layers of glass in well sealed new window frames.

Another way is to add a layer of drywall to the front wall with an airspace between the original wall and the new drywall panels using a metal channel.

If it is a rental and you can't make changes, keeping the windows closed is the best thing that you can do.

Thanks a lot for these inputs! It is a new flat which we have recently bought therefore we can make the required changes.

The wooden windows with 1 layer of glass are mounted on a wooden frame. We can add another glass layer but how to seal the side gaps between the wooden frames is not clear to us. We seek your advise...

Closing the windows blocks the air!! So?
