No large N experiments. but Feynman in one of his autobiographies tests this with a friend. One of them hears numbers, the other sees them. They are unable to multitask within the domain they use to process numbers. I for one hear numbers. I can count while performing visual tasks. My father sees them. He cannot. He can speak and count, which I find amusing.

I can read and count, but not speak and count. While trying this out, I realized I can not count silently, but am always pronouncing the numbers in my head. I wonder if that is related?
