Estimation and global control of noise reflections
Emmanuel Friot, Alexandre Gintz
In theory, active control could be used to reduce the unwanted noise reflections from surfaces such as a submarine hull or the walls of an anechoic room. In the recent years, a rea…
Active control of scattered acoustic radiation: a real-time implementation
Emmanuel Friot, Régine Guillermin, Muriel Winninger
This paper presents an active noise control experiment designed to validate a real-time control strategy for reduction of the noise scattered from a three-dimensional body. The con…
Infinite non-causality in active cancellation of random noise
Emmanuel Friot
Active cancellation of broadband random noise requires the detection of the incoming noise with some time advance. In an duct for example this advance must be larger than the delay…
Active control of sound inside a sphere via control of the acoustic pressure at the boundary surface
Nicolas Epain, Emmanuel Friot
Here we investigate the practical feasibility of performing soundfield reproduction throughout a three-dimensional area by controlling the acoustic pressure measured at the boundar…
Indoor Sonic Boom Reproduction Using ANC
Nicolas Epain, Emmanuel Friot, Guy Rabau
The European programs for development of supersonic air-flights involve new studies on the human perception of sonic boom. Because this noise includes high-level components at very…
