Noise from 60 km/h – what was not there before

Hello, after about 26,000 km and almost 3 years it suddenly rushes in our Ibiza from 60 km/h. Since the sound comes from the direction of the windscreen wiper, which I changed 3 weeks ago, I removed this one today, but it did not bring any improvement. On both sides of the windscreen are loosely acting plastic covers, but it looks like it should be. My wife and I both think that the noise occurs only recently. a similar problem for you, an idea of what this could be and how to fix it.
