    Default Noise Testing

    I don't know why but for once more I want to do an upgrade and this time in audio/noise measurement equipment.

    So I hear your suggestions on sound analyzers or anything else. I already have a good db meter but I don't think that this is enough.

    A company already proposed me this one along with the M2230 measurement microphone.

    You have to much money?

    Imo you reviews are already great, probably te best. There is one thing I would love tot see, and thats this at room temperature. Most modern cases don't have the PSU on the topside anymore. I know its a lot of work, but it makes it more usefull.

    Try adding spectral analysis of noise profile. Maybe it will make it clear what's the source of noise output - just airflow or do bearings contribute audibly?

    Thank you guys for your replies!

    @-The_Mask-
    Nope I am not rich, however I try to improve constantly my methodology and not leave it the same for ages even if it is already good. Unfortunately many times these improvements need for extra tools. For example my latest improvement in the hold-up tests demanded for an expensive scope, but thankfully I managed to get a sponsorship on it. And of course I have TPU and W1zzard to back me up As for the graph you asked below the one you showed, in my reviews I provide one with the PSU's noise at normal ambient (or at least much lower) throughout all load range. So I think that this covers what you want

    @rafal_iB_PL This is what I need an audio analyzer for but the thing is that I don't know much on this area (models, their capabilities, software etc.) so I will need some time and feedback too, from anyone that knows this area. I might email Silent Mike who is an expert in this field to guide me through.

    Not really dBA doesn't says much to me, I prefer RPM. I know that different fans don't make the same noise because off the shape, bearing and other noise. But still I prefer RPM.

    RPM measurements are very cheap and reliable. I'd love to see them.

    I have RMPs already but only for hot tests. BTW I am on the verge on buying a B&K sound meter which costs and arm and a leg

    found a nice sound analyzer But it costs almost as much as a Chroma mainframe loaded with loads.

    That plus an anechoic chamber sounds like a little bit more cost/effort than it's worth. :/

    I don't have room for an anechoic chamber. I barely have room for my staff as it is now
