Abnormally Loud Sounds

I usually play with relatively low volume for sound effects and just most poe sounds to make it easier to hear loot filter sounds. However with the recent 3.2.0 patch some instances of boss fights/phases are extremely loud. I'm not sure if this is a bug or setting I'm missing but the following fights I have noticed a loud sound effect.

-Any Kitava fight whenever he absorbs his heart again makes a loud "crashing" sound similar to thunder.
-Whenever the Elder is absorbing/infusing a boss soul
-Atoll map boss charging up it's tidal wave attack
-Vilenta had a loud sound effect but cannot recall exactly which

I will try to update this as I find more.
