In the following passage about mechanical-switch keyboards, which keyboards are the loudest, and how can I make them quieter?

Context:
Every key on a mechanical-switch keyboard contains a complete switch underneath. Each switch is composed of a housing, a spring, and a stem, and sometimes other parts such as a separate tactile leaf or a clickbar. Switches come in three variants: "linear" with consistent resistance, "tactile" with a non-audible bump, and "clicky" with both a bump and an audible click. Depending on the resistance of the spring, the key requires different amounts of pressure to actuate and to bottom out. The shape of the stem as well as the design of the switch housing varies the actuation distance and travel distance of the switch. The sound can be altered by the material of the plate, case, lubrication, the keycap profile, and even modifying the individual switch. These modifications, or "mods" include applying lubricant to reduce friction inside the switch itself, inserting "switch films" to reduce wobble, swapping out the spring inside to modify the resistance of the switch itself and many more. Mechanical keyboards allow for the removal and replacement of keycaps with a common stem type.<|im_end|>

Mechanical-switch keyboards with "Clicky" switches come with both a bump and an audible click. Without adjusting the material of the plates or case, the way for users to reduce the noise would be to replace the keycaps or applying lubricant to reduce friction inside the switch.<|im_end|>
