What a waste of loo roll/water.
Just do a poo for goodness sake. Nobody cares about your toilet noises, people

An Otohime in a women's room: The black square is the motion sensor for starting and stopping the sound
Many Japanese women are embarrassed at the thought of being heard by others during urination[41] (see paruresis). To cover the sound of bodily functions, many women flushed public toilets continuously while using them, wasting a large amount of water in the process.[41] As education campaigns did not stop this practice, a device was introduced in the 1980s[3] that, after activation, produces the sound of flushing water without the need for actual flushing. One brand name commonly found is the Otohime (Japanese: 音姫), which literally means Sound Princess, and is named after the Japanese goddess Otohime (the goddess's name, though, is written with different kanji (乙姫) meaning "younger princess"), the beautiful daughter of the sea-king Ryūjin. This device is now routinely placed in most new public women's rooms, and many older public women's rooms have been upgraded.[41] The Otohime may be either a separate battery-operated device attached to the wall of the toilet, or included in an existing washlet. The device is activated by pressing a button, or by the wave of a hand in front of a motion sensor. When activated, the device creates a loud flushing sound similar to a toilet being flushed. This sound either stops after a preset time or can be halted through a second press on the button. It is estimated that this saves up to 20 liters of water per use.[3] However, some women believe that the Otohime sounds artificial and prefer to use a continuous flushing of the toilet instead of the recorded flush of the Otohime. So far, there appears to be no demand for these devices for men's public toilets, and the devices are almost never installed in men's restrooms.[42][/expand]
