The reverberant field is an integrated sum of intensities arriving from all directions

Evidence

The steady-state sound level, at a given point in the room, therefore is an integrated sum of all the sound intensities in the reverberant part of the sound, as shown in Figure 6.9. Because of this behavior the reverberant part of the sound in a room is often referred to as the “reverberant field.” — David Howard, Jamie Angus, coustics and Psychoacoustics, 1787

Categorization

• DEFINE: Clarifies the technical sense of reverberant field as a sum of intensities, grounding the concept.
• XREF: connects to: Steady-state reverberant level is set by the balance between input power and absorption loss — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1742; Reverberant fields supply most perceived loudness in normal rooms — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1776
