The goal is to design and develop an auditory substitution device that through the use of vibro-tactile stimulation can substitute for regional frequency hearing loss.

The final presentation and paper have been completed and can be viewed in the Presentations and Reports section of this webpage.
At the end of the first semester, we were able to separate recorded sound into 4 different frequency channels, amplify and discriminate the outputted voltage, and fire the corresponding trandsducer. Troublesome high frequency sounds can be separated using our device. Please view the final report and presentation for more details.
| Week | Reporting Period Beginning | Activities |
|---|---|---|
| 1 | September 8 | Met with client, began initial research, created project statement |
| 2 | September 15 | Began work on PDS, continued research, brainstormed |
| 3 | September 22 | Finished rough draft of PDS, continued research, brainstormed |
| 4 | September 29 | Began thinking of mid-semester device design ideas, split specific PDS details for further investigation |
| 5 | October 6 | More on mid-semester device design ideas, PDS updated, mid semester presentation started |
| 6 | October 13 | Met with client, continued work on presentation and design ideas, perfected presentation, prepared for delivery |
| 7 | October 20 | Wrote mid-semester design report |
| 8 | October 27 | Researched conversion of wave forms, circuit building, frequency separation, etc |
| 9 | November 3 | Assigned design roles for each team member, began finding components to order, started to design circuit with amplifier |
| 10 | November 10 | Met with client, bought sound card, continued research for design |
| 11 | November 17 | Worked on creating multiple frequency channels through the sound card, researched the ranges each channel should have, discussed discrimination of certain voltages for circuit |
| 12 | December 1 | Designed circuit to amplify and separate voltages, four separate channels of frequency were obtained from Cool-Edit software and the sound card |
| 13 | December 8 | The ciruit was completed, the design was put together and finalized, the final poster was made, the final presentation was perfected and performed |
