MINECARTS

Hello. I am making a server and I used a minecart in the "GAMES" Lobby. I find it annoying that the minecart makes so much noise. Could you please add a future /gamerule in which the desired entity (in my case minecarts) won't make noise? I tried the /summon minecart

{silent:1}

command but it didn't seem to work, unless i'm doing it wrong? Please fix this.
