If I don't know how to read Arabic language and just listen to the Holy Quran or recite the Holy Quran by following the audio.
Does these these to acts have equal rewards?
Allah has sent this book so that people understand it. When they will do that, it will effect their actions and make their lives better.
[This is] a blessed Book which We have revealed to you, [O Muhammad], that they might reflect upon its verses and that those of understanding would be reminded.
Reading or listening the Holy Quran without understanding defeats the very purpose of this book.
