Kurze Antwort
According to game.guide's survival guide, every action has a noise number: crouching 6, walking 14, low radio 22, sprinting 32, melee hit 35, hammering 55, breaking glass 70, shouting 70, loud radio 90 and the generator 110. Noise draws the infected, so crouch near doors and keep the radio low. The guide doesn't say what the numbers measure, so read them as a ranking, not metres.

What the numbers tell you
The list runs from 6 to 110, and the big jumps are the ones you control. A loud radio (90) is far above a low one (22), and the generator (110) is the loudest thing on the list. game.guide's page on the basement says the generator charges batteries but "calls them".
Two things you do every day sit in the middle: dragging furniture (38) and hammering (55). That matters on Day 3, when you drag the couch to brace the door, and when you build the rooftop shelter.
What the game itself says
The game's own text agrees on the direction, even without numbers. The Custom Music Radio game pass description says the infected hear any battery radio, and the in-game rule book says to listen before opening a door and that noise travels. Our radio page covers the controls.
We haven't measured the numbers in play, and we don't know the distance at which each one is heard. Treat the table as a ranking of how risky each action is.
Tips
- Crouch (6) when you pass doors you don't want to wake; walking is 14, sprinting 32.
- Keep the radio low (22), not loud (90).
- Do the hammering jobs (55) while the hallway is quiet, not when something is at the door.
- Don't shout (70) or break glass (70) unless you mean to.
- Leave the generator (110) for when you can afford the attention.
