@adrianwong2468 I think I see what's going on.

The building is modular: the ground floor is commercial, the rest is residential. All commercial buildings generate noise, according to game mechanics. To be honest, I forgot about that, and it hasn't occurred to me earlier, because I have installed Pollution Solution mod long time ago.

I'd suggest two possible solutions:

1. Add local RICO settings for sub-buildings (HK Mark 1 block shops and HK Mark 1 block milk bar), so that they are offices or any other noiseless service, or disable RICO for these sub-buildings.
2. Or simply install and enable Pollution Solution mod.

That's really unexpected, as these buildings have zero noise values on them. I've checked them once more in the editor right now, and all of them have zero noise radius and noise accumulation, where these parameters are applicable. Also, placed them in the game, waited till they get populated, and still there's no noise around them. Here's a screenshot, only a road is noisy: https://prnt.sc/10apavi
Could it be that a nearby road generates extra noise in your game?

aparently the sounds are too loud again so that the citizens instantly move out
