Description

This invention relates to a noise suppression system, a noise suppression method, and a program. Techniques are known for making wall materials sound-insulating to prevent noise from leaking outside from indoors (see, for example, Patent Document 1). Japanese Patent Publication No. 2013-113744 This figure shows an example of the overall configuration of the noise suppression system according to this embodiment.This figure shows an example configuration of the device control system according to this embodiment.This figure shows an example of device control information according to this embodiment.This figure shows an example configuration of a data storage server according to this embodiment.This figure shows an example of sound collection data according to this embodiment.This figure shows an example of user information according to this embodiment.This figure shows an example of the analysis results information according to this embodiment.This figure shows an example configuration of the analysis server according to this embodiment.This flowchart shows an example of a processing procedure performed by the equipment control device according to this embodiment in relation to noise suppression control during a meeting.This flowchart shows an example of a processing procedure performed by the equipment control device according to this embodiment in relation to a pre-warning as noise suppression control. [Example of a noise reduction system configuration] Figure 1 shows an example of the overall configuration of the noise suppression system of this embodiment. The noise suppression system of this embodiment aims to suppress noise generated from the indoor RM space by making users U (speakers) participating in a meeting in the indoor RM space conscious of reducing the volume of the voice they emit when speaking. In the following description, the indoor RM will be given as an example of a situation where a meeting is being held in a conference room located in a company building, and users U are employees. The indoor RM includes a sound collection sensor 10, an equipment control device 100, a smart remote control 20, a smart outlet 30, equipment 40-1, 40-2, 40-3, a monitor 40-4, and a user terminal 40-5. Unless otherwise specified, equipment 40-1, 40-2, 40-3, monitor 40-4, and user terminal 40-5 are referred to as equipment 40. The sound collection sensor 10, for example, is equipped with a microphone and collects sound in the room RM, and outputs sound data (collected sound data) obtained from the sound collection. The smart remote control 20 controls the operation of the device 40-1, which is the target of control, by wirelessly outputting control signals such as IR signals. In the figure, an example is shown where the smart remote controller (hereinafter referred to as the smart remote control) 20 controls only one device 40, but the smart remote control 20 may control multiple devices 40-1. The smart remote control 20 is configured to transmit command signals corresponding to the operations specified by the control data output by the device control device 100 to the device 40-1 specified by the control data. The smart remote control 20 is configured to control various electronic devices from various manufacturers, for example, through manufacturer settings and model settings. The smart remote control 20 and the device control device 100 may be connected wirelessly, for example, by Bluetooth® or a wireless LAN, or they may be connected by wires, such as by Ethernet or various data interfaces. The smart outlet 30, for example, is equipped with a predetermined number of power strips and can individually control the power supply to the devices 40 connected to the outlets. Any devices 40-2 can be connected to the outlets of the smart outlet 30. In the figure, an example is shown where one device 40 is connected to the smart outlet 30. However, the number of devices 40-2 that can be connected to the smart outlet 30 is not particularly limited, as long as it is within the number of outlets provided on the power strip. The smart outlet 30 and the device control device 100 may be connected wirelessly via Bluetooth® or wireless LAN, or they may be connected via wired connections via Ethernet or various data interfaces. Devices 40-1 and 40-2 are installed in the room RM and are controlled to perform predetermined actions (noise reduction promotion actions) aimed at motivating users U to suppress the amount of speech they make when speaking to them during a meeting. The types of devices 40-1 and 40-2, and specific examples of actions corresponding to each type of device will be described later. The device 40-1 controlled by the smart remote control 20 operates in accordance with the control signals transmitted from the smart remote control 20. The device 40-2 connected to the smart outlet 30 operates when power is supplied from the smart outlet 30, and stops operating when the smart outlet 30 stops supplying power. Furth
