For those living in disaster prone areas, the wail of an outdoor warning siren routinely disrupting your peace is all too common. These loudspeakers, that make up the often county-wide network of disaster warning system, has to be regularly tested, but instead of blaring their horns and needlessly jangling the nerves of the citizens, why can’t outdoor warning sirens play soothing music during tests? That’s precisely what progressive nations like Japan do.
