I think there was non cherry mechanical switches (gateron?) that had the same/similar feeling but are less noisy, you should look around for some mechanical keyboard/switches reviews and see for yourself - maybe even go into some shops and try them out.
Alternatively you could of course just get anything but white/blue/green switches, which are basically silent.
My coworkers did point out that the boss will now know when I am working or not tho based on the loud clicks :P so consider that also!!
