I think you need to be more precise here in terms of what kind of noise,
i.e. spectrally and magnitude-wise... I have looked at your company's
website and if the product we are discussing here is the one mentioned
there, then my guess we are not really talking about a 120 dB system, but
maybe about 90 dB at best. Basically, for this sort of application I believe
you should be happy with average PC sound quality. So, how much noise do you
actually have?
With regards to PCB passes, you might be able to do some experimenting if
you panelize PCBs in house vs. in PCB shop. This way you can place a few
different ones on one panel for free...
