Activity Four: Walking toward a sound source
The following conditions involve localizing a sound by
walking an arbitrary distance to locate the position of the
sound source. The distance a learner must walk to locate
the sound source is left up to the instructor’s judgment.
If a learner has had little experience with this activity,
starting at a distance of 5 feet and working up to
distances of 30 feet may be a successful approach. Skill
in localizing sound will increase with practice; therefore,
the following conditions may be performed as many times
as needed. However, do not be discouraged if a learner is
less precise at farther distances. This is a natural outgrowth
of the human perceptual system and takes much practice
to counter.

1. Assume initial position: Learner stands facing sound
source, a specifi c distance from sound source.
Instructor: “Walk to the sound.”
2. Have learner stand with sound source behind him, a
specifi c distance from sound source.
Instructor: “Make a half-turn to the left/right; walk to
the sound.”

3. Have learner stand in front and equidistant from two
sound sources (i.e., Place one sound source on the
right and one sound source on the left).
right and one sound source on the left).
Instructor: “Walk straight ahead until you are directly
between the two sounds, then stop. Turn right and face that
sound. Point at the sound, then walk to the sound.”

4. Repeat condition three by having learner turn left
when he reaches the midpoint between the two
sound sources.

5. Repeat condition three and four but eliminate the
sound source opposite the direction in which the
learner is turning.

Activity Five: Walking away from a sound source
Repeat each of the conditions in the previous activity by
reversing each walking pattern.

when I turn off the sound.”
