Crackling in hearing aid for loud S/SH/F sounds

Hi,

I swapped to a vented sleeve in my left ear, before I used an open dome and I am noticing that when presented with loud S/SH/F sounds or for example when opening a water tap my left hearing aid starts crackling. Could this be because the gain gets too close to the max output of the receiver? See picture

Is it normal for a hearing aid to start crackling like this when reaching its max output?

Don’t know if it’s normal but I’ve found the same with my Phonak’s, they are all crackly due to reaching the max output.
