1. A system, for implementation at a vehicle of transportation, comprising: a hardware-based storage device; multiple arrangements of occupant-zone-specific acoustic equipment in the vehicle, wherein: each arrangement is positioned at a respective occupant-specific acoustic zone of the vehicle; each arrangement is configured to communicate with a processing unit that, when executing code of the hardware-based storage device in operation of the system, interacts, via the arrangement, only with a vehicle occupant occupying a corresponding occupant-specific acoustic zone; and the hardware-based storage device comprising an activity module that, by way of the processing unit in operation of the system: obtains first-occupant-identifying information in response to a first occupant booking use of the vehicle; determines, based on the first-occupant-identifying information, a first identity, of a first vehicle occupant, occupying a first occupant-specific acoustic zone of the occupant-specific acoustic zones; and associates, by the processing unit, in the storage device, the first identity determined with data indicating the first zone.
