How does the PE Foam Mod work?

The PE foam mod works by altering the way sound waves are transmitted through the keyboard case and into the surrounding environment. When you press a key on a mechanical keyboard, the switch creates a sound wave that travels through the keyboard case and into the air.

However, not all of the sound waves are desirable. Some waves can be distorted or cancelled out by reflections or resonances in the keyboard case, which can lead to a less satisfying sound.

The PE foam mod works by absorbing some of the unwanted sound waves and reducing the effects of reflections and resonances in the keyboard case.

The polyethylene foam used in the mod is a lightweight and porous material that is good at absorbing sound waves.

By placing small pieces of foam on top of each switch on the PCB, the foam acts as a dampening material, absorbing some of the sound waves generated by the switches and reducing the amount of sound that is reflected back into the case.

This can lead to a more uniform and deeper sound that is often described as “thockier” or “bassier” than before the mod. By reducing the effects of unwanted sound reflections and resonances, the PE foam mod can help to create a more satisfying and enjoyable typing experience for mechanical keyboard enthusiasts.

And while the exact effectiveness of the PE foam mod can vary depending on the keyboard and individual preferences, it works by using polyethylene foam to absorb unwanted sound waves and create a more uniform and satisfying sound profile.
