Beschreibung
Zusammenfassung:	The invention is an apparatus used to send sound exterior to the vehicle to a location on the interior of a vehicle which corresponds with the sound's external location. The apparatus adjusts for gain by frequency and shifts frequencies of the audio signals received exterior to the vehicle to generate a modified audio signal. The adjustments include compensation for hearing loss, compensation for audio in the interior of the vehicle, and attenuation adjustments for unwanted exterior noise. The modified audio signal is generated by filtering unwanted audio from the exterior audio, adjusting for gain by frequency and shifting/compressing frequencies according to hearing deficiencies, and adjusting for gain by frequency according to audio in the interior of the vehicle. The modified audio signal may be limited to a maximum gain and then amplified in the interior of the vehicle.
