The present invention describes a system and method for reducing the risk of infant suffocation. A behind-the-ear hearing aid of the present invention is used while fitted to an ear of a human body, and includes at least a microphone 101 which collects ambient sound, thereby generating an input signal and signal processing unit 102 that generates an output signal from the input signal. of a solution obtained by dissolving 0. while flowing an inert gas at the space velocity of 0 to 120. When the rear support leg is placed inside a bathtub or shower and the front support leg is placed outside the shower, fluid entering the basin by gravity from the reservoir and through the openable spigot exits via the drain hole and empties into the bathtub or shower or a waste water receptacle.
