Why Add Damping Foam to Your Keyboard?

The decision to add damping foam to your keyboard can significantly enhance your typing experience. While it may seem like a meticulous process, the benefits you’ll reap make it a worthwhile endeavor. Moreover, you might already have suitable foam materials lying around your home.

Here’s why you should consider adding damping foam and how it can transform your keyboard:

  1. Deeper and More Bassy Sound: The most noticeable impact of adding foam is the improvement in the keyboard’s sound. Typically, the keyboard becomes less high-pitched and acquires a more pleasing, subtle, and bassy sound. This auditory upgrade can be highly satisfying for users.
  2. Reduction in Metallic Spring Ping Noises: Keyboards often produce unpleasant metallic ringing noises. This can occur when the metallic plate vibrates during typing or when the springs inside the switches vibrate. Adding damping foam helps dampen these vibrations, resulting in a quieter and more enjoyable typing experience.
  3. Increased Keyboard Stability: The addition of foam, especially materials like Sorbothane, adds weight to the keyboard. This extra weight minimizes unwanted keyboard movement while typing, making the overall setup feel more secure. With added stability, the only moving parts will be the keys themselves when you press them.

These benefits make adding damping foam to your keyboard a valuable modification. Whether you choose to invest in foam or utilize materials you have on hand, the improvements in sound quality and typing experience are worth the effort.

How to Add Damping Foam to Your Keyboard

The process of adding damping foam to your keyboard can vary depending on the type of foam you use and the design of your keyboard case. Here’s a general guideline for the installation process:

  1. Disassemble Your Keyboard:
    • Remove the keycaps from your keyboard to access the internal components.
    • Locate and remove all the screws that secure the PCB (Printed Circuit Board) into the case.
  2. Case Opening:
    • Some keyboard case designs are held together by plastic clips. In such cases, you’ll need to gently unclip and release the components, working your way around the keyboard until the case pops open.
    • The specific method of disassembly can vary based on the design of your keyboard.
  3. Add the Foam:
    • Once you have access to the interior of the keyboard case, cut the damping foam to fit the available space.
    • The process may vary depending on the type of foam you are using. Cheaper foams like packing foam or shelf liner may require layering and stacking to fill up the space effectively. Sorbothane and neoprene are generally thick enough to require only one layer.
    • You may need to experiment with the amount and placement of foam to achieve the desired sound and vibration reduction.
  4. Reassemble the Keyboard:
    • After adding the foam, carefully reassemble the keyboard components in the reverse order of disassembly.
    • Replace the keycaps and secure the screws to hold the PCB in place.
    • Ensure that all components are properly secured and that the keyboard functions as intended.

By following these steps, you can successfully add damping foam to your keyboard, resulting in a quieter and more satisfying typing experience. Remember that the specific procedure may vary depending on your keyboard’s design, so be prepared to adapt accordingly.


In conclusion, achieving a quieter typing experience is attainable with the right sound dampening foam for your keyboard. Consider your specific needs and budget to determine the best option for you. Whether you choose advanced materials like Sorbothane or opt for cost-effective solutions like packing foam or shelf liner, your keyboard can become a much quieter and more pleasant tool for work or play.
