Total loudness includes contributions outside the stimulus’s own band

Evidence

The area below the specific loudness pattern again corresponds to total loudness. This area, however, is concentrated not only in that region in which the narrow-band noise is physically present, but also shows slope-specific loudnesses towards lower, and especially towards higher critical-band rates. — Professor Dr.-Ing.

• DEFINE: Clarifies that total loudness = area under the whole specific-loudness pattern, including slope contributions outside the physical band.
