While driving my 90 Prevost, I hear a humming sound...any ideas.....Prevost thinks its the air horns, but I covered them with duct tape and its still there
Sure it isn't you?...Cable
birds? ;D

Does the sound change with the throttle? Is it speed related? Does it do it at idle?

I agree try whistling and see if it goes away :)

I once had a a mechanic that would tell me to turn up the radio a bit if a complained to him about an odd noise.
Maybe you have Glenn Gould's ghost in your bus.
Hummmmmm. . .

Lin,
That mechanic must have trained several of my drivers as well!
I often find the stereo BLASTING in the buses and when I run it out to fuel it or whatever and notice a strange new noise I get
"What noise? I didn't hear noth'n!"(of course not ya moron you couldn't hear ya self think as loud as the stereo was!)
But on the other hand Blaupunkt makes one hell of a bus sound system! ;D
;D BK ;D
There is nothing needs fixing on my bus, ever, but they hear me coming!!
Have you invited someone to drive while you search, or vice versa? Most noises I have looked for cannot be found, after I stop.
I am usually alone when I hear them, but doing walkabouts for noises at 45 MPH, I hear that is not safe.
The last hummer I detected was associated with power steering. Full reservoir, but still made noise. That one comes and goes - I will find it someday.
ck gasket around spare tire door.....some times air relays make a sound simular to humming when not operating properly but should not be constant...Is it under co piolt seat?
What kinda tune is it? Rock, country, hip-hop, blues, gospel, etc? ;)
Seriously, if we knew the tone or tune it makes it might be easier to hunt down.
;D BK ;D
Sounds like fun.
Are you any closer?
TENITUS ;D
Sure - go ahead - Blame the driver
Our '65 MC 5A has a "hum" in any gear when it gets to around 1900 RPM. It seems to set up a "harmonic" kind of hum to the bus.
