Hello everyone

I'd like some advice on using a mechanical keyboard with family members around, I'll post a short and a long version, choose which you like depending on your mood to read
Short version: Do Brown Switches make so much noise during nighttime, that other family members may wake from typing? Do they make that much noise that it might irritate others to a point I can't use the keyboard anymore?
Long version: I've wanted a mechanical keyboard for the last couple of years, I love the sound of them, the robust built of them and I basically love typing (I even type urls in the browser, i have auto-complete disabled

).
Thing is, I still live with my parents. Given the nature of the switches, they are louder than membrane keyboards. I fear that if I buy a mechanical keyboard, it might be so loud that I won't be able to use it during nighttime. Sure, I've watched Youtube videos but I cannot judge correctly, can I?
Also, Greece doesn't have a market really for mechanical keyboards, stores don't have a variety of them (a couple of Razers and that's it) so if I buy one online, it'll be a blind purchase which is risky, because I'll have to live with it if I don't like it.
So I'm stuck here, I have no way of trying mechanical keyboards, all I can do is purchase online from the US, and I have no way of knowing if they'll be noisy as hell...
I can always use my laptop during nighttime though, if the mechanical keyboard is too noisy, that's a good thing hehe

I'm drooling over a Leopold Tenkeyless with Brown switches, I've read they're quite noiseless so...
What do you guys say about mechanical keyboards and leaving with other people? Can it be done or is too risky? (especially on my case...)
