摘要： Provided is a device for detecting sound outside vehicle capable of detecting sounds outside the vehicle with high accuracy in various surrounding environments.
A sound source direction detecting ECU 1 acquires sound collection information about sounds outside a vehicle which are collected by microphones 2A to 2G. The sound source direction detecting ECU 1 acquires traveling road information about the vicinity of a host vehicle on the basis of the acquired sound collection information. When the traveling road information is acquired, the sound source direction detecting ECU 1 adjusts the sound collection characteristics of the microphones 2A to 2G on the basis of the traveling road information.
