Abstract
A system and method for enhancing a proximity warning sound may determine an indicator of a distance between a first object and a second object. A proximity warning sound may be generated including a reverberation mimicking component responsive to the determined distance indicator; where a human listener perceives the reverberation mimicking component included in the audible proximity warning sound to be indicative of the determined distance indicator.
