At 50 MPH and up, I hear a loud sound ( like blowing over a coke bottle) Liberty Coach thought it
was the air horns, however I covered them and the sound is still there....any ideas...thanks Dave
I think you have the right idea --- it's just something else not the air horns.
Hard to guess what it could be --- did it just start or get worse?
Give us a few more clues or we will feel like Bob Seger --- working on mysteries without any clues

I noticed that on my ticket widow the slider seal is worn out, I do get a slight wind noise as the airflow goes around the gutter that runs down the outside of the pillar. Or the noise could be the airflow coming around your mirror. Just a few things to check.
Check the top of the entry door or make yourself a small cardboard air dam tape on in different places then you can close in on it
good luck
I used a helper to assist in pinpointing many air noises. The a little tape or such to make a temporary fix to see if it works. I still have some noise at the top of my entry door but haven found the best way to stop it yet. (It is an RV style door)
I have made the bus pretty quiet. I can actually have a conversation with someone riding in the back now without yelling. It makes it easier to hear criticisms as well! ::) Best of all it has helped tremendously in cooling over the road.
Depending on wind direction my passenger side, side view mirror makes a driveyounuts roar.

Had a similar problem last year. The wife walked all over the bus till she found the bathroom window wasn't closed tight...Cable
Get a stethascope and connect a funel to the end of one hose. The funnel makes it directional and you can walk around search out noise sources. Rumbling cabnets and panels being low freq are especially hard to pinpoint by naked ear alone.
I bought a directional mic from Radio Shack so I could do this alone from the drivers seat. Point click and read the noise in db. Works great but you can do the same thing for $50 less.

John, how I would have loved to have seen you driving down the road with a stehescope in your ears connected to a funnel! Can you imagine what the passing motorists must have said?
Thanks!
