Adding sound to a DCC diesel

[CapJack]

Can a sound decoder be added to a Bachmann SD40 DCC equipped engine?  If so what brands of sound decoders will work?
Thanks!

What are called resistors are 4.7 microhenry ferrite inductors. Zero resistance. All Bachmann DCC locos come with them. Some are wire wound. I measured them on my locos with an inductance meter. Many confuse them.

I should have remembered SoundTraxx. You could substitute their parts. I am assuming you have experience.
