Abstract
A vehicle approach notification apparatus includes a first sounding signal generation portion that generates a first sounding signal based on a first sound source data; a second sounding signal generation portion that generates a second sounding signal based on a second sound source data; and a combination portion that combines the first sounding signal with the second sounding signal to generate a notice sound signal. The first sounding signal generation portion changes a frequency and an output level of the first sounding signal depending on a speed of the vehicle. The second sounding signal generation portion changes an output level of the second sounding signal depending on the speed of the vehicle while holding a frequency of the second sounding signal to be constant.
