Brand sounds heard across summoner's rift

While playing Zombie Brand in intermediate bots with some friends, everyone says they can hear me spamming the skin's joke and that it was very loud on their end. So we tested it again and again and concluded that no matter where I am, my team can hear all my jokes, laughs, taunts, and random noises regardless of champion distance or camera placement. I later tried it out again in normals and in ranked. Same thing happens. My team really hates it, but I love it spamming it.
