This is just my personal experience. My first son was able to read when he was 2.5 yo. I read Dr. Suess to him every night since he was 1 yo. At first I would read and let him finish the last word in the sentence, the rhyming part. One day I asked him to try reading the whole sentence and he did. I thought maybe I read to him so much that he memorized it, as I was starting to memorized some of the books. I switch to different book and he was able to read a few sentences. I tried a book we haven't read yet (higher level Dr. Suess's book) and he was able to read 20%. Taking turn on the pages made it fun and I tried to exaggerate some of the words to make it more dramatic, like CRASH!!!.
Another thing I think help was that we put him to sleep with a radio station playing classical music since he was born, maybe even before that. Being a public support station, they tend to have sponsor promotions quite a bit, so my son was listing to classical music and people talking. I believe the music and the talking sound got him to be familiar with English phonic early, so when it comes to reading, the rhythm is not so strange.
Sadly, with the second son, we had to split time with two kids and more work, we didn't do the same routine. He was barely reading when he got into kindergarden. But thank God he had a great teacher in 1st grade, over zoom she taught most of the class to read. My kids actually excelled during pandemic teaching over zoom. Of course we were there to help them along.
I think reading is priority one for any kid. Once they learn to read, they are more independent, read menu and decide for themselves, read instructions to build LEGOs, read street names, really open the world to them.
So I started learning. I learned in different ways, you know - to watch German movies, play German speeches on my iPod when I sleep. Your brain remembers things you don't even know. It's beautiful.
Learning by listening to something during your sleep doesn't work. Brains go into a sort of maintenance mode during sleep, and it's not possible for your brain to sleep and interpret & comprehend sensory input at the same time.
Most likely the noise will have a negative effect on the length and quality of your sleep, which does have a proven negative effect on memory.
So it's probably better for you to learn while your awake and just sleep at night.
