Has anyone tried this to silence an air pump?

First please don't try this, as I'm not 100% sure it's safe yet. Still doing research on the components.

But it's simple, rather than putting your airpump on something, or in something, I put some filter foam inside my airpump to absorb the vibration. And I'm stunned at how well it works. It easily reduced the noise by half.



I was thinking about taking this a step further by perhaps using expanding ventilation foam (from the can) to fill in all the gaps completely. However that is more of a hard foam so I would still need some flexible foam to put around the moving parts.

My next idea is to buy a block of soft rubber, and make the housing out of that.

And yeah, I'm bored over here.

The sound is most likely coming diaphragm. You might need a new one.
The padding is only making the pump less efficient. It reduced the noise because it reduced the movement of the arm. It's not a bad way to reduce the amount of air going through.

+1 But we only learn from experimenting, right?

Yeah actually that makes a lot of sense! Back to the drawing board

Expanding foam will ruin your pump. That stuff expands with enough force to deform window casements if you dont use enough screws or nails.
