I'd recommend the touch keyboards by GETT. The CK4 and CK5 if you like a compact keyboard more than a full one.

These are the quietest keyboards ever decibel-wise because they have no moving or mechanical parts.

They use capacitive-touch technology.

The Logitech K380 and Microsoft Bluetooth Keyboard are the quietest when it comes to keyboards with moving parts but only for the keys, like most keyboards, the space bar is loud if you have hyperacusis or just dislike that smack/clack/click sound.
