No these are the "silent" reds. They don't make a sound when bottoming out and also not when coming back up.

I made my ergonomic, split keyboards from a kit[1], and chose Aliaz Silent switches [2]. It's around the same noisiness as everyone else's keyboard (Apple, cheap Dell one etc).
(There are almost certainly other options — the choice was a bit overwhelming when I decided to buy a DIY keyboard — but I'm not in the hobby of collecting many different keyboards. Various Reddit groups can advise.)
