Summary:To appropriately set acoustic characteristics of a sound processing device of a vehicle.SOLUTION: A control device 100 for a sound processing device of a vehicle 1 includes a sound output part 60 for outputting sound to the outside of the vehicle, and a sound acquisition part 10 for acquiring sound around the vehicle 1. The control device 100 of the sound processing device includes: a sound analysis part 51 for analyzing the sound acquired by the sound acquisition part 10, and acquiring the value of a feature amount of a specification sound included in the sound as a second value when the specification sound for specifying magnitude of a prescribed kind of the feature amount as a first value is output from the sound output part 60; an acoustic characteristic detection part 52 for detecting acoustic characteristics of the sound output part 60 and the sound acquisition part 10 on the basis of the first value and the second value; and a device control part 53 for executing calibration processing for the sound output part 60 and the sound acquisition part 10 on the basis of the acoustic characteristics.SELECTED DRAWING: Figure 3 【課題】車両の音処理機器の音響特性を適切に設定する。【解決手段】車外に音を出力する音出力部６０と、車両１の周囲の音を取得する音取得部１０とを備える車両１の音処理機器の制御装置１００である。音処理機器の制御装置１００は、予め設定された種類の特徴量の大きさを第１値とする規定音を音出力部６０から出力させた際に、音取得部１０により取得された音を分析し、その音に含まれる規定音の特徴量の値を第２値として取得する音分析部５１と、第１値及び第２値に基づいて、音出力部６０及び音取得部１０の音響特性を検出する音響特性検出部５２と、その音響特性に基づいて、音出力部６０及び音取得部１０に関する較正処理を実行する機器制御部５３とを備える。【選択図】図３
