This was a challenging, complicated and long experiment. I would like to thank a number of people and organizations for their assistance, because without their help this project would not have been possible.

I would like to thank my mother and father who helped me find subjects, made many of the arrangements, drove me to the testing, helped with editing and proofreading and asked me many hard questions that helped me think about the experiment.

I would like to thank researchers David Franklin and Ray Goldsworthy who were generous with their time and answered many of my questions. Dr. Goldsworthy’s insights into cochlear implants were the clue that helped me determine the hypothesis. Mr. Franklin answered many questions and even sent an engineering textbook. Jeremy Cooperstock provided early information that helped to set me on this path.

Without the assistance of the leaders of three local San Diego organizations, it would have been very challenging for me to find subjects and other support. Leslie Elion from Deaf Community Services of San Diego and Marilyn Weinhouse of the Hearing Loss Association of America – San Diego branch, were very helpful.

The third San Diego organization to help out was the Capita Foundation and its president Bart Ziegler and founder Robert Capita. After hearing about the experiment, the Capita Foundation, which sponsors research into hearing loss, provided a small grant to assist with some of the costs of the device I built for this experiment, the K-MAD. Mr. Ziegler also introduced Ms. Weinhouse from HLAA- SD to this project and always gave encouragement. It was a highlight and honor to meet some of the researchers sponsored by the Capita Foundation.

Erika Zettner, an audiologist from UCSD, was helpful in informing others about the project, and some of them became subjects.

Manny from San Diego Electronic Supply sold us the parts for the K-MAD device and helped translate the concept of the device into a schematic diagram. Matan Kaminski helped me understand the schematic diagram and assisted with building it. Engineer Dave Edwards was very kind to repair the device, and later on to provide advice about how to go about repairing it myself when it broke a second time.

Finally, this experiment could not have been possible without the kindness and patience of the 14 subjects who sat for hours listening to the same 15 seconds of Penny Lane by the Beatles over and over again. I thank them for trusting me and giving this experiment their sincere effort. Meeting all of these individuals and hearing their stories was one of the most interesting and motivating parts of this project.
