An apparatus (600, 700), comprising: an interface system; a headset including: a speaker system; and an orientation system capable of determining an orientation of the headset; and a control system capable of: receiving, via the interface system, personnel location data indicating locations of a plurality of persons; receiving, from the orientation system, headset orientation data corresponding with the orientation of the headset; determining first environmental element location data indicating a location of at least a first environmental element; determining, based at least in part on the headset orientation data, the personnel location data and the first environmental element location data, headset coordinate locations of the plurality of persons and at least the first environmental element in a headset coordinate system corresponding with the orientation of the headset; and causing the apparatus to provide spatialization indications of the headset coordinate locations, wherein providing the spatialization indications involves controlling the speaker system to provide environmental element sonification corresponding with at least the first environmental element location data, wherein causing the apparatus to provide spatialization indications further involves controlling the speaker system to provide personnel sonification corresponding with the personnel location data of the plurality of persons, wherein the sonification involves a characteristic sound repeated at a predetermined time interval, wherein the predetermined time interval is different for the first environmental element and for each of the plurality of persons and/or the sonification involving characteristic sound has a different pitch for the first environmental element and for each of the plurality of persons. an interface system;
