The volume of noise is low but the frequency is very strange,

Thanks and sorry for the english.

That's not normal at all. That thing would quickly give me a headache and the urge to fling it out the nearest window!

I don't know. My guess is that something is defective with the decoder and/or speaker. Or perhaps there is something electronic in the local environment that's interfering with it, but that seems less likely. Personally, I would just return it (if that's an option).

Return is not an option,this week I receive my 2-8-4 barkshire,so i can see if it is a local problem. Ebay is sometimes a problem.

Thank you very much.

I first need to preface my reply by stating I have Tinnitus (ringing in the ears) and I'm deaf at the 4300 Hz. hearing range. I can hear sound above and below that range, but not at 4300 Hz. So if your locomotive is making a nose at that range I do not hear it and apologize, but all I hear in your video is the normal Bachmann Sound Value sounds. I hear the constant sound of steam escaping, it's the shhhh or hiss sound that is fairly constant. I also hear the air pump thump thump occasionally. If you press the F8 function key, does the buzz continue or stop? Have you changed any of the CV values? And this may seem like a silly question, but is the throttle set to zero or stop?
