A method, system, and computer-readable media for collecting blast exposure data relating to a blast exposure event from one or more blast sensors and performing a blast exposure analysis that results in identifying the source of the blast exposure event using the blast exposure data. The one or more blast sensors may be communicatively coupled to at least one user device. Such a blast exposure analysis is provided in response to the blast exposure event such that operators may be notified of the blast exposure in real-time.

This application discloses a method and apparatus for determining characteristics of a sound source. The method may include: acquiring a first position of a first virtual role in a virtual scene; detecting, in a sound source detection area associated with the first position, a second position of a sound source virtual object in the virtual scene; determining a position mark identifying the sound source virtual object; displaying a map, the first position in the virtual scene corresponding to a third position on the map; determining a fourth position on the map corresponding to the second position based on the first position and the third position, the fourth position relative to the third position on the map reflecting a direction of the second position relative to the first position in the virtual scene; displaying the position mark of the sound source virtual object at the fourth position on the map.

An acoustically registerable probe includes a transducer (212) to generate acoustic pulses, and a beamformer (222) coupled to the transducer to adjust a field of view of the acoustic pulses. The transducer is configured to iteratively send and receive acoustic energy with a decremented field of view angles to identify a position of the transducer (216) to other transducers and to reveal positions of the other transducers to the transducer through a medium carrying the acoustic pulses to register the transducer to the other transducers coupled to the medium.

Methods, apparatus, systems, and articles of manufacture to determine a location of an audio source are disclosed. Disclosed example apparatus are to determine respective error values for corresponding ones of a first dataset of time difference of arrival (TDOA) distance values between pairs of acoustic sensors, the error values based on a cost function, a first set of constraints and a second set of constraints. Disclosed example apparatus are also to adjust the corresponding ones of the first dataset of TDOA distance values based on the respective error values to determine a second dataset of TDOA distance values. Disclosed example apparatus are further to output the second dataset of TDOA distance values to source location circuitry that is to determine the location of the audio source.

The described aspects and implementations enable privacy-respecting detection, separation, and localization of sounds in vehicle environments. The techniques include obtaining, using audio detector(s) of a vehicle, a sound recording that includes a plurality of elemental sounds (ESs) in a driving environment of the vehicle, and processing, using a sound separation model, the sound recording to separate individual ESs of the plurality of ESs. The techniques further include identifying a content of individual ESs and causing a driving path of the vehicle to be modified in view of the identified content of the individual ESs. Further techniques include rendering speech imperceptibly by redacting temporal portions of the speech, using sound recognition models to identify and discard recordings of speech, and driving at speeds that exceed threshold speeds at which speech becomes imperceptible from noise masking.

A navigation system for airborne vehicles without GNSS data uses at least three microphones positioned at or near a base station. The microphones capture sounds emitted by the airborne vehicle and these sounds are processed to calculate the vehicle's location. The vehicle then makes a series of maneuvers in response to the information received from the base station.
