How to block out sound while sleeping when silence actually makes it worse

Here’s the weird thing I don’t see talked about.

When my room is completely quiet, every tiny sound wakes me up more.

AC clicking,Floor popping, Distant siren.

So How to block out sound while sleeping isn’t about total silence for me — it’s about predictability.

Some setups calm my brain. Others make it scan the room all night.

If you’ve figured out what actually helps vs what backfires, I’d love to hear it.
