A method for reproducing an external sound in an automobile includes recording external sound using external microphones located on an automobile exterior of the automobile; establishing recorded audio signals based on the recorded external sound; determining from the recorded audio signals a relative directionality of external sound sources of the recorded external sound with respect to at least one occupant within the automobile; establishing at least one directionality encoded audio signal by applying at least one frequency dependent directionality filter to the recorded audio signals, wherein at least one frequency dependent directionality filter is based on the determined relative directionality of external sound sources, thereby encoding the relative directionality into said at least one directionality encoded audio signal; reproducing a representation of the external sound based on at least one directionality encoded audio signal using internal loudspeakers located within an automobile interior of the automobile.
