Acoustic Stealth Technology Finally Created 83
smitty777 writes "An idea for acoustic stealth technology proposed in 2008 was finally put into practice. The abstract describes taking advantage of the 'transformation acoustics and linear coordinate transformations that result in shells which are homogeneous, broadband, and compact. The required material parameters are highly anisotropic; however, we show that they are easily achievable in practice in metamaterials made of perforated plastic plates.' It is thought this technology might be useful for shielding ships from sonar or creating soundproof rooms."
Soundproof rooms (Score:2, Insightful)
Please for the love of $DEITY make this a reality. Right now low frequencies are impossible to block so it's impossible to soundproof a room against those godamn fucking annoying boomcars.
