Sound Proof Panels Made of Latex and Buttons – Practical Application of Metamaterial Physics
Metamaterial sound proofing from materials less than an inch thick would be as good as 4 foot thick walls for soundproofing. People outside a metamaterial sound proofed room – no one will hear you screaming inside Applied Physics Letters – Acoustic metamaterial panels for sound attenuation in the 50–1000 Hz regime The Hong Kong University …
