In the frequency characteristics converting apparatus, a sound emitter is located at a first position on an inside of a vehicle, and in response to an increase in magnitude of noise at the first position, volume of target sound, collected by a sound collector installed at a second position, is increased when the target sound is emitted by the sound emitter, and a degree of signal processing that is applied to the target sound is increased.",
