Yes, I consider it the natural resonances of the room. All rooms have a
"seashell effect", ala the Helmholtz resonator.  The Audio Cyclopedia taught
me this.  It is much louder than the self noise of a quiet mike, except in
extremely exceptional circumstances. Rooms really do put out "tones."  And
when I'm on the subway in New York, I found that the subway puts out
"tones", too.  In fact I hear "tones" everywhere I go.  Am I mad?

I have had one experience where there was a relative absence of room tone. I
was experimenting with a figure-8 mike, in a room that had plenty of tone to
the ear. The figure-8 mike made it appear absent by comparison. Then, a
couple hours after I started recording, I discovered that the mike weren't
plugged in.  This explained the relative absence of room tone.

Now I'm going to eat some Twinkies.
