I can only agree. the tunnel is super. Every time the train sound travels through a different sound (overall I think 3 or 4 different). That's always exciting and interesting for my son. The volume I find not too unpleasant or disturbing! At the point I can not agree. We have two battery-powered trains and making itself also already sounds. If the tunnel is now quieter, then you would have the ear right up close. But even with a wooden train, I find the tunnel is not too loud.
