ABSTRACT:
In a vehicle alarm sound output device and a program, position data of an obstacle(s) and sound data of an alarm sound are output from an obstacle detector to DSP of a virtual sound source generator. Position data of a tire having air pressure abnormality and sound data of an alarm sound are output from an abnormality detector to DSP. Position data of a target object of a route guidance and sound data of a voice are output from a position detector to DSP. In DSP, an audio signal with which a virtual sound source can be implemented is created by using a detection signal/localization position converting table and head related transfer functions, and the audio signal thus created is output to a sound output unit. In the sound output unit, the signal corresponding to the audio signal is output to speakers so that a passenger(s) can hear an alarm sound such as a warning sound, a voice guidance or the like from the localization position of a virtual sound source.
