Abstract

PURPOSE:To properly grasp the state of the outside of a vehicle in terms of sound without imposing a burden on a driver by applying required sound volume attenuation when an alarm tone is sensed from an ambulance car at the outside of its own vehicle. CONSTITUTION:The driver operates properly an operation section 25A in a radio function section 2A to apply channel selection. In this state, when an alarm sound from, for example, an ambulance car is sensed by a specific tone sensor section 26, a prescribed condition signal is fed to a mute section 22 via a switch 27A. Thus, the output sound from the speaker 3 is reduced remarkably to listen to the alarm tone clearly.
