pieces of furniture have been moved in the room, based on
how the room sounds.
In addition to paying attention to how self-motion relative
to the fi eld of ambient sound indicates features of the
environment, the acoustic characteristics of directionality,
pitch, timbre, intensity, and envelope both for direct and
refl ected sound are used to distinguish between acoustic
environments (Kish, n.d.). These characteristics of sound
are also affected by the material off of which sound is
refl ected. With practice, a person can perceive increasingly
subtle variations in position, size, texture, shape, distance,
and even composition (Kish, n.d.). With practice, people
have been able to sense the presence of small objects from
2 to 3 meters away (Jones & Myers, 1954; Myers & Jones,
1958; Rice, Feinstein, & Schusterman, 1965), ascertain the
lateral location of a single object to within a few degrees
(Rice, 1969), determine the shape of objects (Hausfeld,
Power, Gorta, & Harris, 1982; Rice, 1967a, 1967b, 1967c),
and identify textures of surfaces (Hausfeld, Power, Gorta, &
Harris, 1982; Juurmaa, 1970b; Kellogg, 1962).

By developing awareness of and sensitivity to these
often subtle acoustic cues, a person who is blind can
make use of sound to learn a great deal of information
about her environment.

Animal Chase
This game is best played on an asphalt court or in a gym
approximately 50 feet wide. All players line up along one
side, and “it” takes his place in the middle of the playing
area. He calls the name of some animal, such as dog, cow,
or cat, whereupon all the players must run across the playing
area, imitating the animal designated. Anyone caught before
reaching the opposite side must join hands with “it” and
help her catch other players. The original “it” remains the
caller throughout the game. The last one caught is “it” for
the next game.

Variations: 1) The game can be played by assigning a
specifi c animal to two or three players. When that animal is
called, only those who represent it run across the court. 2)
As each player is caught and join “it,” he gets to call out the
next animal. 3) Place a portable sound source on each side
of the gym. 4) “It” wears a sound source.

Blue Bird (circle game)
Players stand in a circle, holding hands, arms up, which
signifi es that the windows are open. One or two blue birds
are in center. As you sing the song, the birds weave in
and out the open “windows.” The bluebird with blindness
