1
Kill the Reverb
2
Echo: Biggest cause why your voice sounds cheap is not microphone performance but room reverb. Flat wall bounces sound. Need to kill (Dampen) that reflection with acoustic foam
3
Elgato Wave Panels: Product that changed concept of acoustic foam. Combine hexagonal panels like puzzle and decorate on wall as part of design. Installation and removal are instant with EasyClick frame
4
TroyStudio: Acoustic foam with strongest cost performance. Appearance is rugged but performance is certain. Wallet does not hurt even if filling whole wall. This is best if making closet simple vocal booth
5
Diffusion: Not only sucking sound completely, but scattering appropriately is also important. Bookshelf and houseplant also become magnificent acoustic equipment

Introduction: Invisible Noise

In online meeting, have you ever heard opponent’s voice “Like being in bathroom”? That is because room wall is reflecting sound.

No matter how expensive suit you wear, if voice echoes, it is not professional. Conversely, voice arriving from dead (anechoic) space creates Intimacy as if being whispered next to you. Adjusting room acoustics is one of grooming.

1. The Designer Choice: Elgato Wave Panels

Overturned common sense “Acoustic foam = Black sponge”. Appearance is beautiful and does not spoil interior. Rather, room changes to Cyberpunk studio by sticking this.

Elgato Wave Panels

ASIN: B091CVZ7RK

Absorbs sound of wide frequency band with 2 layer structure (High density foam + Low density fiber). Tape that can be installed without making hole in wall is included so that it can be used in rental.

Easy Setup

What should be mentioned is ease of installation. Just paste frame to wall first and snap panel in. If you want to redecorate, it is possible to remove and replace only panel.

2. The Budget King: TroyStudio

If “Anyway cheap, want to stick in large quantity”, this is it. Appearance is slightly cheap, but physical sound absorption performance is genuine. If you fill one wall in black, it becomes complete studio.

TroyStudio Acoustic Foam

ASIN: B093F7QK4N

Uneven processing of 5cm thickness prevents diffuse reflection of sound. Since it arrives in compressed state, ritual to soak in water and return is necessary, but it is worth sparing that effort.

3. Comparison: Aesthetics or Quantity

項目	Elgato Wave Panels	TroyStudio
Design	Hexagonal (Beautiful)	Square (Business-like)
Installation Difficulty	Easy (Frame type)	Normal (Double-sided tape)
Price	High ($40~ / piece)	Cheap ($5~ / piece)
Absorption Performance	High (2 layer)	Normal (Urethane)

4. The Placement Strategy

No need to stick to whole wall. Import thing is “Primary Reflection Point”.

Wall where sound from speaker hits first (Front and Side).
Wall where own voice hits (Behind monitor).

Just by sticking several sheets here, sound changes dramatically. Please add little by little until unpleasant reverb (Flutter Echo) “Bean” disappears when clapping hands.

Conclusion: Value of Silence

When entering absorbed room, feel unique “Silence”. Outside noise becomes far, hear only own breathing sound. That becomes switch to enter deep concentration.

Not only to deliver good sound, but to protect own peace (Sanctuary). Please hack wall.
