Abstract
A device for room geometry analysis comprising: a plurality of segments (-) built of acoustic metamaterials, each segment (φ, θ) acting as a waveguide with a unique transfer function (B(φ, θ, ω)); and a processor configured to calculate delays (τ(φ, θ)) and respective directions (c(φ, θ)) of mirror sound sources (-) by decomposing a sound signal (Ŝ) obtained from a microphone () based on the transfer functions (B(φ, θ, ω)) of the segments (-) and based on a calibration signal (tsp(t)) emitted by a speaker ().
