ABSTRACT:
An example apparatus for providing an audible signal representative of an environment comprises a sensor system, and an audio system providing an audible signal to a person. The audible signal has one or more audible signal variables from which the person can determine, for example, the location and relative velocity of one or more objects within the environment. The apparatus includes an electronic circuit for converting environmental data into audible signal variables, for example using a mapping algorithm.
