A server (NS) for providing a quieter environment in an open work space comprising a plurality of work places WP11,..., WPij,... WPnm respectively used by a plurality of users; comprises a processor configured for: - receiving (41), at the instant t, digital audio signals ANij(t), for i = 1 to n and j = 1 to m, corresponding to the ambient noises respectively captured by microphones at the work places WP11,..., WPnm; - computing (42) average values Lij(t), for i = 1 to n and j = 1 to m, respectively representing the current noises at the work places WP11,..., WPnm, at the instant t; - computing (43) a threshold value THij(t) that represents the current noise, at the instant t, in the neighbourhood of the work place WPij as a function of p values Lij(t) respectively representing the current noises at p work places that are neighbors of the work place WPij; - comparing (44) each digital audio signal ANij(t) with the threshold value THij(t) for i = 1 to n and j = 1 to m; - then determining (45) what are the digital audio signals ANij(t) that are respectively greater than the threshold values THij(t) for i = 1 to n and j = 1 to m, for determining at least one work place that corresponds to a digital audio signal ANij(t) that is greater than the threshold value THij(t); and then notifying a warning to the user of the so determined work place. |
