They’re inherently louder. But they’re not always inherently loud. There’s a lot of different switch types, and some are loud on purpose. So if you get a keyboard with blue switches they’re going to be loud because they’re specifically intended to be both tactile(you feel a ‘bump’ when the key activates) and loud (you hear a click when the key activates). I had an internet buddy with blue switches, and the whole fucking chat knew when he was typing because his mic picked it up.

Personally I like tactile keys, but I absolutely hate loud keyboards. So I have brown switches- they have the tactile ‘bump’ that I like the feel of, but they’re not obnoxiously loud.

You can also go with red switches, and those are just straight up-down switches. No bump, no click. They’re generally the quietest common switch, especially if you’re not whaling on them. There’s roughly a billion other types of switch, as well. It’s not just blues, browns, and reds. There’s even “silent” switches. I have zero experience with those, though, so no idea how silent they actually get.

Note: I’m not crazy into mechanical keyboards. I just did a bit of research before I bought one awhile back. So… grain of salt and all.
