    There’s nothing you can do about it – unless the brick the author recommended actually works.

    This experiment tests for microphonics in the equipment’s electronic components. That means how they pick up noise sources and translate that noise back through the speakers. Which means the “problem” isn’t a problem at all unless you start playing something – in which case the program source will cover it probably dozens of times over.

    Personally I’d be more worried about the non-microphonic noise floor of the system – what it generates with no signal present. Unless you can hear noise at the seating position, with the volume turned up to your normal listening level and an empty input selected, I wouldn’t loose any sleep over this.
