Depends on how good your hearing is I guess. For me to hear it I have to be next to it with everything else in the room turned off. But my hearing isn't stellar, and I'm well known for being able to tune noise (people) out
But regarding the point you may be getting at - the lower flow rate did make a difference in how loud the "ticking" was, it got quieter - and more still as bits of moss and plants get stuck in the vents.
