The invention relates to an acoustic protection system used to secure a determined zone of interest and to remotely control an individual or a group of individuals within this zone and with a potentially hostile behavior. The system comprises at least one set of N electro acoustic sound sources forming a network and a generator used to create N electrical signals output from a same reference and that can be controlled in phase individually. Each electrical signal is input into a determined sound source, the assembly creating a resulting emission for which the diagram depends on the direction of the zone of interest and the distribution of required active and quiet zones. The device also comprises means capable of determining the relative positions of the different sources after they have been deployed, thus limiting positioning constraints imposed on operators responsible for deployment and making the work faster. The purpose of the invention is more generally the domain of non-lethal protection devices.
