Is there a workaround against a noisy soundtrack of a .mp4 video loaded on youtube?

I made an experimental video in “Filmora” and then converted it to .MP4 format (conversion done by Filmora).

This is the video:

The .MP4 file plays well directly from my laptop. The sound has no distortion. Unfortunately, after downloading the video on Youtube the sound becomes bad, there is a lot of noise, parasites, also I play the video with the same computer and the internet speed is good.

Do you know what can be done to get rid of this noise?
