I am visiting Japan, I went into a couple of huge Pacinko and slot arcades, just wanted to see them live.
I noticed in both of them a very strong almost unbearable noise, not coming from the machines, more similar to a jet engine or a huge airflow or a strange white noise. I also noticed big loudspeakers around the arcades.
I know well the noise of video games arcades, this is completely different.
Is it possible that the noise is transmitted through the loudspeakers for some reason related to how there venues work? If this is the case, why?
