Sound insulation around air duct to plate fan

[Appendix]

As I wrote, the noise is fixed. The pipe is enclosed today and makes almost no sound.

Ahh ok. Just saw now it was a half-year-old thread

Then it's good that everything worked out, and I hope you didn't have to do anything and that the contractor solved it
