Title: Minimizing Spacebar Sound
Post by: mashby on Thu, 13 June 2013, 12:24:59
I have a Poker with MX-Black switches and I tend to really smack the spacebar and I'm looking for ways to minimize the sound. I added three 50A-R O-Rings (http://www.wasdkeyboards.com/index.php/cherry-mx-rubber-switch-dampeners.html), the black ones, and that didn't seem to help much. I'm still getting a plastic like slap.

This isn't a unique or different sound from what I'm accustomed to with the SP spacebar, just one I've finally decided to do something about. I may just have to take the keyboard out of the case and look under the key cap to see  what causes it, but that would take work, so I figured I'd ask here instead.  :p

Any suggestions?

the black rings doesn't dampen much at all.. and You should record the mysterious "slap sound".. I've not heard any spacebar sound described as you have.

Try a heavier spring imo. I smack my spacebar too (only key I bottom out on), but it makes a nice solid sound. Maybe it's the upside down thick PBT? :p

upside down doesn't change the sound from my experience..

Could the concave bar be serving to amplify the noise?  Maybe stuff some noise dampening foam or something in it and see if it quiets it?

I'm using a stack of o-rings (but I have an OEM-profile aluminum spacebar at the moment): a fat o-ring, followed by a 50A thin o-ring.  I also add small squares of teflon tape into the spacebar stems.  All helps to dampen the sound of metal quite a bit, where it mostly just sounds like a soft thump in normal use.   Some combination of that is probably good for plastic too.

I just got in some MX-Grey switches, so I'll be taking apart my Poker this week and swapping it out. When I do, I'll take a closer look at exactly what is causing the sound.

I think it's just the sound the spacebar makes, coupled with the Cherry stabilizers, but I'll take some video too to see if  I can better identify the cause of the sound.

try clipping your stabilizers.  It makes it feel and sound much more like costar stabilizers.

Did you also put O-rings on the stabilizer contact points? I have red O-rings and it just makes a thock sound, and it would be still loud if I only put a ring on the center one.

If it was costar stabs then I would be concerned with bent stabilizers, but with cherry, I guess your best bet would be getting a heavier spring and stop smashing the key. Also, could someone redirect me to a guide on fixing costar stabs?

My Poker (also with blacks) also has a quite loud space bar, but I find the noise seems to be on the way back up rather than the initial slap. I release the space bar quite quickly so it gets the full force of a black thrusting it triumphantly into the air, until it hits the top of the switch and sounds out a plasticy slap.

If I can find my soldering iron I will change the switches around on the space bar to see what different switches sound like.

They are cherry stabilizers and the sound is on the down stroke and is not a slapback. My schedule has changed, so I won't be able to play with changing out the switch and testing a few things until next weekend.  :-[

I appreciate everyone's feedback and suggestions though. Keep them coming!

Swapped out the MX-Black with an MX-Grey and that definitely solved the issue. It's not a much more solid "thunk" which matches the best the rest of the keys.

I bottom out when I type and the spacebar is not exception. Now that I've been typing on the board for a week it has a very consistent and solid feel, which I like very much.

Thank you to everyone who offered suggestions and ideas.
