If you really believe that the horn is ringing, add mass, lots of mass to the whole horn. Concrete, bricks, sandbags, lead, virgin geishas - anything, just a lot of it then listen again.

Whenever I feel blue, I start breathing again.
There is not enough mass there for a 200Hz ring. I don't know what you are hearing, but you need to go back to whoever built these things and tell them your stories.
