Can You "See" Sound? 1. If you were deaf, how could you see sound? You have all seen receivers in a stereo system that have meters that indicate the various sounds that are being produced by the speakers. In this case as the tape, record, or CD is activated, a current is sent to the meters at the same time it is sent to the speakers. In this way you can "see" the sound as well as hear it. 2. Lets build a non-electronic device to observe sound. You will need an oatmeal box or coffee can. Remove both the top and bottom of the box or can. Stretch a balloon or rubber sheet over one end of the box/can and secure with a rubber band or string.
