There is no visual/UX-design for confirmation (aka sychnonous) notifications on UbuntuTouch... and I don't know if they are meant to be added in the future.
As of rev385 of lp:indicator-sound the triggering of a confirmation notification was added. The lowest impact work-around I can currently think of is to make lp:unity-notifications (the new notification- backend) silently swallow such notifications without adding them to the queue, thus not making them display at all under unity8.
