Keyboard Key Switch Loudness Comparison
Ranking of Key Switch Noise Levels
Here's rank of noises of keyboard key switches. The ranking is based on practical use, not from pressing a single key. The ranking is from my own experience of using of keyboards since 1991 plus watching many internet videos.
Crazy Click-Clack Loud
- Buckling Spring Key Switch. Loudest.
- Cherry MX Blue switches.
- Cherry MX Red switches. MX Red is silent if you press it slowly. But the noise came from key hitting bottom.

Where Does the Key Noise Came From
Some switches intentionally make a noise, such as Cherry MX Blue Clicky and Buckling Spring Key Switch
Most switches do not make much noise if you press them slowly.
The noise came from:
- The key hitting bottom. (try hit a key hard and fast, and hear the sound hitting bottom. This sound is similar if you hit desk with your finger fast. Try it. You get knocking sound.)
- Key bouncing back. (try this: press down the key slowly all the way, then move finger side way off suddenly. The key pops back by spring, “hits top”, makes noise.)
- Key housing. For example, the spacebar. The spacebar make the loudest noise, especially those from cheap rubber dome computer keyboards. e.g. Microsoft Natural Ergonomic Keyboard 4000
- Friction noise. The spring, stem, keycap, together makes noises. Especially on cheap rubber dome computer keyboard.
Rubber O-Ring Noise Dampener (No Good)
One way to reduce noise is to buy those rubber ring switch dampeners. You put them in each key yourself.
I do not recommend it. Too much trouble, also it doesn't help much.
