摘要： PROBLEM TO BE SOLVED: To provide a vehicle outside warning device warning the approach of a vehicle to pedestrians and a warning method thereof.
SOLUTION: When a pedestrian 41 exists in front (for example, 10 m ahead) of a vehicle, an output device radiates ultrasonic waves toward a road surface in front of the pedestrian 41. The ultrasonic waves radiated from the output device 16 causes nonlinear interaction in a step propagating in air and reflecting on a road surface, and recovered to voice which can be heard. The road surface when the ultrasonic waves reach becomes a virtual sound source 42. The pedestrian 41 can hear the recovered alarm sound like as the alarm sound is generated from the virtual sound source 42, and can notice the approach of the vehicle 20 from the alarm sound.

摘要： PROBLEM TO BE SOLVED: To provide a method for a new signal separation that can be applied even when a sound source having diffusion is included.
SOLUTION: This method is introduced for automatically detecting and eliminating a frequency band wherein a diffusion signal source or a noise level is high and a target signal source is hard to separate by an ICA (Independent Component Analysis) as an undesired band. For this purpose, a cost function for evaluating independence between input signals is defined, a threshold is set in the cost function, a suppression constant is calculated in each frequency band by using the threshold, and the undesired band can thereby be automatically detected and eliminated.
