Abstract: A device for room geometry analysis comprising: a plurality of segments (101-106) 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 (721-725) by decomposing a sound signal (Ŝ) obtained from a microphone (110) based on the transfer functions (B(φ, θ, ω)) of the segments (101-106) and based on a calibration signal (tsp(t)) emitted by a speaker (420).

Abstract: A device for active noise control inside a vehicle, the device comprising a processor (7610) configured to determine a noise wavefield within the vehicle based on noise signals captured by a microphone array (M1-M10); determine the position of the ears of a passenger (P1) based on information obtained from a head tracking sensor (HTU1); capture a noise field inside the vehicle based on information obtained by the microphone array; obtain a noise level at the ears of the passenger (P1) from the noise field; and determine an anti-noise field based on the noise level at the position of the ears of the passenger.
