Hey DWAYNE, I bet you turn the "music/ambient" volume off in the options like I`ve always done. I`ve read about the "heartbeat" in the forums but never bothered `till now to check it out.
Sorry to say, it does exist, if you turn the volume up and hit a ball within ten feet. Maybe you could try the ol` "if a tree falls in a deserted forest" angle ;), for myself, I can`t stand the music so I`ve muted it again.
