ly 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 inter-
acting 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 pro-
cedure 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 neu-
tral. 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 bound-
aries of the rectangle.
6. Repeat this process for each speaker location individually. These are your
Zones of Neutrality, one for each channel.
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.
