PROBLEM TO BE SOLVED: To automatically adjust the sound volume of a sound of a sound output apparatus appropriately by providing a detecting means which detects the usage of the apparatus to generate sounds, and a control means to increase/decrease the sound volume of the sound based on the detection output. SOLUTION: On a hot water supply path 21 to introduce hot water of which the temperature has been raised from a hot water supply apparatus 2 to a water faucet 11, a flow rate sensor 62 to detect the hot water supply amount, is provided on the upstream side. A television device 3b is equipped with a sound output unit 34 to output the sound of the television, and a sound increasing/decreasing apparatus 36 which increases/decreases the volume of the sound in a plurality of steps. In addition, a sound volume control circuit (not shown in the illustration) in order to automatically increase/decrease the sound volume based on the detected flow rate of the flow rate sensor 62, is provided. The sound volume control circuit increases/decreases the sound volume step of the sound increasing/decreasing apparatus 36 based on the supply amount of the hot water to a bathroom 1, which is fed through the water faucet 11, and increases/decreases the output sound volume from the sound output unit 34. Therefore, the volume of the sound is appropriately increased/decreased to the volume of the sound which generates due to the supply of the hot water. |
