Block states, Sound
Make a debug world, and use the command below to teleport to the barrels.
/execute in minecraft:overworld run tp @s 209.10 73.20 29.87 844.68 56.05
Notice that the barrel keeps making its "closing" sound.
This seems to be an issue with barrels constantly setting their "open" state to false.
/setblock ~ ~ ~ minecraft:barrel[open=true]
Using the above command will make the barrel close, unlike other blocks that keep the state specified when placed with /setblock.
