An audio device designed to replicate the sound of flushing water has been unveiled in Japan as an alternative to actual flushing done to mask the sound of using the lavatory.
According to its inventors, Japanese women have traditionally regarded as distasteful the natural sound of using the lavatory, and they waste thousands of liters of water each year by flushing to help conceal it.
Experts suggest this new device can save much water when compared with conventional method to mask the sound.
The device is installed in each bathroom stall and will simulate the sound of running water when women touch a sensor, China Radio International reported Thursday.
