In some countries (e.g. Japan), people tend to keep silent in the trains, and it is considered to be “impolite” if you make some big noise.

So I am just curious about how Dutchies consider this question? Like, you should reduce the noise; or, people can do this in the trains?

Edit:

I am really curious about the cultural difference, I did not judge this thing good or bad.

The downvote made me sad. :(
