If measurement is made indoors, you'll see mostly the room (not the speaker) unless gating is used in order to ignore reflections. When gating is used, it is called a pseudo-anechoic measurement, because the influence of reflections doesn't appear in the data. You can gate some signal types, and others you can't. But frankly, all the subtleties that are exposed using various signal types would be swamped by room influence, if the measurement isn't gated to ignore reflections.
