3. At some point during your progression forward into the room, you will observe a sonic transition in your
voice; it will sound more tonally correct and less spatially diffuse (your assistant can now precisely
localize the exact origin of your voice). When you hear this transition, you have entered the inner edge
of the “Zone of Neutrality.” Place a piece of tape on the floor to mark this location. Although it will
vary from room to room, the zone in most rooms begins between two and a half or three feet from the
rear wall.
4. Continue to walk slowly away from the rear wall. After some distance, usually one to two feet past the
first piece of tape, you will begin to hear your voice lose focus and appear to reflect (echo) in front of
you. This is caused by the return of the room’s boundary contribution; your voice is now interacting
with the opposite wall. At the point where you begin to hear the reflected sound of your voice, you
have reached the inner edge of the “Zone of Neutrality.” Place a piece of tape on the floor and mark
this location. The distance between the “inner” and “outer” edge tape marks is usually between eight
inches (for small, interactive rooms), and three feet (for large, more neutral rooms).
5. Now position yourself against the side wall perpendicular to the intended speaker location. Stand
between the two tape marks. Using the same procedure as above, begin moving into the room toward
the opposite side wall, progressing between the two pieces of tape. As above, listen for the point in the
room where your voice transitions from bass-heavy and diffuse to neutral. Mark this point with tape.
Continue your progression until there is an obvious interaction with the opposite wall in front of you and
mark this point with tape. The four pieces of tape now form a rectangle that establishes the Zone of
Neutrality for the loudspeaker located on that side of the room. Using the four marks as your guide,
tape an outline to define the boundaries of the rectangle.
6. Repeat this process for each speaker location individually. These are your Zones of Neutrality, one for
each channel.
Theoretically, the Zone of Neutrality for any room runs like a path, parallel to the walls all around the room.
Adjacent to very large windows and open doors, the outer edge of the Zone of Neutrality moves closer to the wall
and becomes wider. If you were to extend the inner and outer boundaries of the Zone for the side walls and the
front wall (behind the speakers), they would intersect. After you complete this procedure for the other loudspeaker,
you will now have two rectangles, one on the floor on either side of the room.
Note: The more reflective or “live” sounding the room is, the more difficult it will be to detect
the changes in your voice; thus, you may have to repeat this process until the zones have been
determined.
