Immission, not emission. Generally the regulations deal with noise made by humans and especially their appliances. Also, of course there are exceptions, e.g. for children.
And yes, 35 dB(A) is achieveable. A hospital at night is no place to have a party around. Also nobody will wait for you to run around in high heels to give you a fine. But if you regularly do that in your flat and your neighbor below is sick of it, that might get you in trouble.
Edit: does anyone think downvoting will change those facts? 🤡
