It’s not like the foam ones eliminate all sounds. I work in a noisy environment and can hear people perfectly fine with earplugs in. They just reduce all sound and your brain kind of compensates.

Just check the NRR (noise reduction rating) and trial and error some. Everyone has different ears. I personally like Howard Leight Max earplugs as they are soft and block a lot of noise.

I’ve had it improve grammar on some legal documents I had to submit and also generate a safety plan for a specific job I was working on. It did both of those things ok but I still had to edit and delete sections that weren’t relevant
