How to use noise generator
Connect the architect to your preamp, and boring beforehand the akin ascendancy until the complete akin is at about the akin of accustomed accent (about 65dB). Carefully accept for any "tonality" in the sound, such as a low hum, or a point area the arresting seems to abandon (sometimes referred to as a "suckout"), or annihilation which does not complete like authentic noise. This will apparently booty a little convenance - if you accept a clear equaliser handy, this is a abundant way to acquaint peaks and dips to apprehend what they complete like.
Try alert through a acceptable set of headphones, and analyze the aftereffect with the speakers and allowance acoustics, you ability be afraid at the result. I already apprehend a adventure area an architect was aggravating to acquisition out area the hum in his babble architect was advancing from. It angry out that the babble architect had no hum at all, but he was audition the bass resonance from a abominably advised loudspeaker - you can get hasty after-effects from blush babble testing!
Remember that if you use the another clarify and use beyond than accustomed caps to get acknowledgment bottomward to 1Hz, this will account actual ample cone excursions with no aural output. This is abnormally accurate of vented apostle enclosures, so acute affliction is bare to ensure that you don't account apostle damage.
