Dispensers firing wind charges, or custom projectiles created by addons, will play the 'random.click' sound event to all players in the world, regardless of distance. This bug affects all platforms and includes BDS servers. I've included a POV of a player activating dispensers with wind charges as well as firing a custom projectile, and a player hearing both events from thousands of blocks away. I've tested this both with and without behavior and resource packs and verified that this is a persistent bug.
