For anyone who is suffering from this, or on some days finds it hard to sleep I recommend Science and Futurism With Isaac Arthur podcast.

It has "Narration Only" versions of all episodes and it is very interesting, so if you can't sleep you can listen to it but it will not have harsh noises.

Also Philosophize This has the same properties (very old episodes have some loud music).

Let me know if you know similar podcasts.
