Cases, Plates, and Other Sound Tests: How Components Affect Your Keyboard's Acoustics
A keyboard's sound is influenced by more than just switches and keycaps—your case material, plate type, and internal dampening all play a huge role. In these sound tests, I compare different cases, plates, and mods to help you find the best setup for your desired sound profile.

Why My Sound Tests Are Reliable
I test all components under controlled conditions—using the same switches and keycaps—so that you hear the real differences caused by the case, plate, or modification. Many sound tests online mix different setups, making it hard to pinpoint what’s actually affecting the sound. My method ensures the most accurate and fair comparisons.
Case Material Sound Tests
The keyboard case significantly affects the overall sound, from deep and muted to sharp and resonant. Here are some of the cases I’ve tested:
-
Aluminum Cases – Often produce a sharper, more metallic sound with less flex.
-
Polycarbonate Cases – Softer, with a more muted and bouncy sound.
-
ABS & Plastic Cases – Typically brighter and higher-pitched.
-
Wooden Cases – Unique acoustics with a natural, deeper tone.
Plate Material Sound Tests
The plate sits between the switches and the PCB, affecting sound and typing feel. I’ve tested different plate materials, including:
-
Aluminum Plates – Stiff and high-pitched with a crisp bottom-out sound.
-
Brass Plates – Deep and rich with a "thocky" sound signature.
-
Polycarbonate Plates – Softer, with a more dampened sound.
-
FR4 Plates – Balanced acoustics, slightly deeper than aluminum.
Carbon Fiber Plates – Lightweight, bouncy, and slightly muted.
How to Choose the Right Case & Plate for Your Sound Preference
- Want a deep, thocky sound? → Brass plate with a polycarbonate case
- Prefer a soft, bouncy feel? → FR4 or polycarbonate plate with a gasket-mounted case
- Looking for a bright, crisp sound? → Aluminum case with an aluminum plate
- Want to reduce hollowness? → Try foam or silicone dampening mods
FAQ: Cases, Plates, and Mods
What’s the best plate material for a thocky sound?
Brass and FR4 plates tend to bring out deeper acoustics, while polycarbonate plates help soften the sound.
Do aluminum cases sound better than plastic cases?
It depends on your preference! Aluminum cases are sharper and more resonant, while plastic cases can be softer and more muted.
Does foam inside the keyboard really change the sound?
Yes! PE foam, plate foam, and case foam all change how sound resonates inside the keyboard, making it deeper or poppier.
