Compression & NoiseBlock

I had my speech in noise NoiseBlock set to moderate and ever since then, I’ve noticed a huge different in clarity when in noise.

Before it wasn’t set at all, my speech in noise just turned to directional.

Why do I feel like I’ve got more clarity in noise?

Would it be that my Naidas were going into compression a lot of the time in noise?

My left naida is being compressed within 15db and my right naida is being compressed within 30db.
