I think Simo is absolutely right. Seems like you have some problems with E-tubes opening. What method of equalizing were you using before Frenzel? Was it successful?
BTW, this "Ng" sound is something what bothers me a lot.
Every time while doing CW dive, when reaching 25m, I have to stop because I can't equalize. The only thing I can do is this "Ng". My VTC is something like 6l and I just can't believe this depth to be the one for doing moutfill.
Everything goes right until some 20m where I have to equalize my mask and after that I just can't make Frenzel work.
