Russell, Are you sure these are room ambients? They might be the analyzer noise floor. Generally, a decent room will not admit signals high enough to be seen above the instrument noise floor. Even a poorly built one should attenuate 60 dB or better and only show a few, discrete ambients from nearby, high-power sources.
