1. A frequency characteristics converting apparatus comprising processing circuitry configured to, in response to an increase in magnitude of noise at a first position in a vehicle, increase volume of a target sound in emitting the target sound by a sound emitter and increase a degree of a signal processing applied to the target sound, the sound emitter being located at the first position, the target sound being collected by a sound collector installed at a second position, wherein the signal processing includes concurrent processing of preventing howling of the target sound and equalizing frequency characteristics of the target sound from the sound collector and to the sound emitter.
