The loudspeakers deployed by South Korea to wage psychological warfare against North Korea faced audits and legal battles claiming they are too quiet, raising questions over how far into the reclusive North their propaganda messages can blast.
South Korea resumed loudspeaker broadcasts directed at North Korea on June 9 for the first time since a now-defunct inter-Korean agreement banned them in 2018.
The current speakers are among 40 systems purchased in 2016 after the two Koreas exchanged artillery fire in a 2015 dispute over the broadcasts.
