Document Type and Number:
WIPO Patent Application WO/2017/203688
Kind Code:
A1
Abstract:
A noise estimation processing unit (20) acquires various types of information from a window open-close sensor (7), a vehicle speed sensor (8), a camera (9), a GPS receiver (10), a memory (11), and so on, and estimates noise levels at respective seats in a vehicle. A balance fader control unit (21) outputs a balance fader control signal, and performs control so that the sound volume of a speaker (6a) to (6d) corresponding to a seat in the case where noise is relatively large becomes smaller than the sound volume of a speaker (6a) to (6d) corresponding to a seat in the case where noise is relatively small.
