Is it just me or hollywood movies are harder to hear??

Why is it when the characters are talking the audio is so low and muffled, and I've never encountered this with movies in my native language or even in Korean dramas, like I don't even understand korean but I can hear every syllable pronounced clearly?? Actually they talk a bit too loudly ngl. it because english is my second language or just a way english is spoken? Is this exclusive to a specific genre of movies?? And I'm pretty sure this is only a thing in movies because I can understand native English speakers on YouTube pretty well. Maybe old age has caught up with me and I'm finally losing my hearing??
