is important that the child be able to track that

2. Following a ball in a sporting event. When developing
basic skills for later playing goalball, a child must be
able to auditorily track a ball rolling on the fl oor and
predict where that path will take the ball in relation to
the child’s position.

3. Tracking vehicles. When standing on a street corner,
waiting to cross, a person often does not want to
move their body unnecessarily in order to keep their
alignment relative to the crossing. However, they
might want to be aware of and track cars passing by
them to determine whether they are turning or not.
Depending on the particulars of the intersection, the
person might need to make a decision to cross based
on the path of these cars.

1. Aligning one’s self to passing traffi c. When waiting at
a street corner, perhaps after locating and pushing a
pedestrian pushbutton, a person often has to align
themselves to passing traffi c. Whether this is done in
relation to perpendicular or parallel traffi c, the task
requires that a person auditorily follow the path of a
moving vehicle and then move their entire body in
reaction to the path of that vehicle.

Activities Three to Five: Following a moving
sound source, walking parallel to a moving
sound, and walking parallel to a sound while walking
a 90° angle

1. Matching paths with a passing person or object in
order to follow it. When walking with a group of
people or following one particular person, it is often
useful to simply follow the sound of their voice or
footsteps. Being able to discriminate that person
from any background noise and notice if they turn
and change your own path accordingly can be a
sophisticated use of sound.

Activity Six: Localizing sound when moving in
opposition to the sound source

1. Walking up to a curb based on the sounds of idling
traffi c. In some situations a person approaches an
intersection and must use the approaching traffi c to
gauge where the intersection is. When walking up to
an intersection with the parallel street on the right, if
no traffi c is currently traveling in the same direction
as the pedestrian, the sound of perpendicular
or oncoming traffi c must be used to gauge the
pedestrian’s position relative to the street. When
the pedestrian is crossing the street, perpendicular
traffi c is stopped and only the sound of oncoming
