    Abstract: Systems, methods, tangible non-transitory computer-readable media, and devices associated with detecting and locating sounds are provided. For example, sound data associated with sounds can be received. The sounds can include source sounds and background sounds received by microphones. Based on the sound data, time differences can be determined. Each of the time differences can include a time difference between receipt of a source sound and receipt of a background sound at each of the microphones respectively. A set of the source sounds can be synchronized based on the time differences. An amplified source sound can be generated based on a combination of the synchronized set of the source sounds. A source location of the source sounds can be determined based on the amplified source sound. Based on the source location, control signals can be generated in order to change actions performed by an autonomous vehicle.
