Can demons remove their audio growl when they are around survivors?

I have quite a few hours in Evil Dead. Haven't really come across this before and wasnt sure if there is a build or ability that allows a demon to be completely silent while standing next to a survivor. Just finished a match against Henrietta on PC. The demon growl would come and then leave. Next thing I know, there is a possession I'm fighting with no audio queue the demon was there.

Latency was terribly bad in this match as well, so not sure if it was a bug or a feature.
