FIG. 7 shows an example in which the size of the noise level icon 702 is displayed larger as the equivalent noise level is larger. However, the present invention is not limited to this, and the output control unit 102 may, for example, determine the shape of the noise level icon 702 and the display color of the noise level icon 702 (color type, color depth, etc.) according to the magnitude of the equivalent noise level. It is also possible to change the decoration of the noise level icon 702, or the characters and images included in the noise level icon 702). Alternatively, the output control unit 102 may change a plurality of types of display formats related to the noise level icon 702 according to a plurality of types of equivalent noise levels related to the real estate. For example, the output control unit 102 changes the size of the noise level icon 702 according to the magnitude of the equivalent noise level outdoors of the real estate, and corresponds to the magnitude of the equivalent noise level indoors of the real estate. The display color of the noise level icon 702 may be changed.

When the noise level icon 702 is selected by the user, the output control unit 102 may display the recorded data of the relevant real estate in chronological order, or the relevant real estate may be displayed, as will be described later. The voice of the recorded data of the above may be output to the user terminal 50.

For example, when a date is selected in the calendar UI 710 and a time is selected in the clock UI 712, the output control unit 102 is equivalent to the voice recorded at the selected date and time for each of the plurality of real estates. It is possible to display the noise level on the map screen 70.

According to the map screen 70, the position information (real estate icon 700) of the real estate and the equivalent noise level icon 702 are displayed in association with each of the plurality of real estates. Therefore, the user can refer to the equivalent noise level of each of the plurality of real estates on the same screen, and can refer to them efficiently. In addition, the magnitude of the equivalent noise level for each real estate can be displayed in an easy-to-understand manner.

-Modification example 1
