Abstract
A method, apparatus and computer program product are provided to permit audio signals to provide additional information to a user regarding the distance to the source of the audio signals, thereby increasing a user's situational awareness. In the context of a method, a distance and a direction from a user to an object are determined. The method also scales the distance to the object to create a modified distance within a predefined sound field region about the user. The method also causes an audio cue relating to the object to be audibly provided to the user. The audio cue is such that the object appears to be located within the predefined sound field region in the direction and at the modified distance from the user from the user.
