A localization system includes a first sensor, configured to detect a vibration and generate a first electrical signal in response to the detection of the vibration; a second sensor, configured to detect a vibration and generate a second electrical signal in response to the detection of the vibration; a third sensor, configured to detect a vibration and generate a third electrical signal in response to the detection of the vibration; and

a processor, configured to determine a position of a source of the vibration based on the first electrical signal, the second electrical signal, and the third electrical signal.

An audio apparatus adaptable to a user position is provided. The audio apparatus may include a plurality of sub-modules placed at separate locations from one another, each sub-module of the plurality of sub-modules including a loudspeaker configured to generate sound and a communicator configured to perform communication. The first sub-module among the plurality of sub-modules may include a processor that processes an audio signal to be output as sound through the loudspeaker of the first sub-module, determines a user's position with respect to each of the plurality of sub-modules, and changes a state of the sound being output from the loudspeaker of the first sub-module in accordance with the determined position of the user.

Aspects of the present disclosure describe distributed fiber optic sensing (DFOS) systems, methods, and structures that advantageously enable city-scale acoustic impulse detection and localization using standard, live aerial telecommunications optical fiber cables through the use of distributed acoustic sensing exhibiting an error of less than 1.22 m.

A positioning system (100) for determining a location of an object is disclosed. The positioning device comprises a plurality of microphones (M1-M6) configured to receive a sound input (122) from a user (120), a localization module (102) configured to determine a user location of the user relative to the plurality of microphones based on differences between the sound input received at different microphones of the plurality of microphones, and a processor (104) configured to receive an identifier of the object, identify the object based on the identifier, determine the location of the object by setting the location of the object equal to the user location, and store the location of the object in a memory.
