One of the quietest rigs I have heard is an AK with a BR Tuote suppressor. Even from the ejection port side, I was surprised at how quiet it is. Listening to 5.56 and 7.62 NATO or 7.62x39 suppressed all in the same range session clearly leaves 5.56 as the more offensive of the three. I'll bet that the Grendel with it's lower pressures and larger bore diameter would exhibit a milder muzzle report when suppressed.
