An audio processing system may selectively identify certain environmental sounds and playing back these sounds, or a representation of these sounds, in the vehicle's cabin. The audio processing system may filter the environmental sounds to identify a particular sound that matches an event such as a bouncing ball, squealing tires, footsteps, and the like. The audio processing system may then provide an audio alert to an occupant in the vehicle. For example, the system may process the identified sound (e.g., amplify and/or isolate the sound) and use a speaker to output the processed sound into the interior of the vehicle. In another embodiment, the audio processing system may use environmental sounds as an audio masking sound for creating privacy zones within the vehicle. The audio processing system may filter the environmental sounds to identify a continuous sound which is then output to generate the privacy zones.
