Gaming keyboards that are quiet, but effective

Are there any gaming keyboards that are quiet when using, but are still effective at being a gaming keyboard? I currently live in an apartment with 2 friends, and they constantly complain about my typing. I tend to work during the day, but sometimes have to work at night, and it bugs them so much when I do any typing or gaming. So, I think I will utilize a different keyboard at night, do you guys have any suggestions?
