Steps to Reproduce
Place down an armor stand. Then execute this command:

/execute @e[type=armor_stand,c=1] ~ ~ ~ playsound minecraft:block.anvil.use master @a ~ ~ ~ 1 0.5 1

Then walk one block away, and execute the command again. Repeat several times. The sound will get fainter and fainter until you step out of the range where you can hear it, and then it will play at full blast, even though you aren't close enough to the anvil to hear it at all.
