PROBLEM TO BE SOLVED: To provide a terminal device which can easily measure a sound field and can correct a sound field characteristic of a cabin.SOLUTION: A portable terminal can communicate with a server which generates sound field correction data by vehicle types by using a plurality of pieces of uploaded sound field measurement data by vehicle types, measures a sound field of a vehicle and generates sound filed measurement data. The portable terminal acquires vehicle type information of the vehicle becoming an object of measurement, acquires measurement position information which displays a measurement position in measurement and transmits the sound field measurement data, the vehicle type information and measurement position information to the server. The portable terminal receives the sound field correction data by vehicle types, which is generated based on the sound field measurement data generated by the vehicle type displayed by the vehicle type information and based on the sound field measurement data generated at every measurement position displayed by the measurement position information, from the server.SELECTED DRAWING: Figure 11 |
