dc.description.abstractDespite the efforts made during the last decades to control noise from subsonic fans, low frequency tonal noise is still of major concern. For those frequencies, passive techniques are bulky and inefficient but active techniques are better adapted and have a great potential for a control at the source. The contributions of this PhD work are (1) the estimation of tonal aeroacoustic sources using inverse models, (2) an acoustic noise control method using a single loudspeaker and (3) an adaptive passive control method using flow control obstructions. Theoretical developments provided in the thesis are valid for subsonic axial fans and experiments were carried out, for an automotive engine cooling fan.fr
