Abstract--In this paper, we investigate several means of
visualizing both ambient and speech sounds and present a
fusion of different visualization displays into one program
package that would help provide the hearing impaired with
a means to an enhanced awareness of their surroundings.
The ideas investigated were implemented in software, and
the program was evaluated by means of a survey conducted
in a school for the deaf.
Index Terms--Ambient Sounds, Autocorrelation Function,
Center Clipping, Pitch, Sound Visualization, Spectrogram,
Speech Recognition.
