Abstract
A vehicle is provided comprising a cabin area, a steering wheel, a plurality of microphones positioned in the cabin area and configured to have pick-up sensitivity in select directions, and a cue generator configured to provide a haptic cue on the steering wheel in response to a sound detected by the plurality of microphones. Also provided are systems and methods for indicating a detected sound direction in a vehicle. A plurality of microphones are positioned in a vehicle cabin and configured to have pick-up sensitivity in select directions. A comparator is configured to compare the detected audio signals to identify a highest amplitude signal. And a cue generator is configured to provide haptic feedback at a vehicle cabin location associated with the microphone detecting the highest amplitude signal.
