begin moving into the room toward the opposite sidewall, 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 sidewalls and the front wall (behind the
speakers), they would intersect. After you complete this procedure for the other loudspeak-
er, you will now have two rectangles, one on the floor on either side of the room.

Probably the most obnoxious form of reflection is called “slap echo.” With slap-echo,
primarily midrange and high frequency sounds reflect off of two parallel hard surfaces. The
sound literally reverberates back and forth until it is finally dissipated over time. You can
test for slap echo in any room by clapping your hands sharply in the middle of the room and
listening for the characteristic sound of the echo in the midrange. Slap echo destroys the
sound quality of a stereo system in two ways:
