1. Sound Therapy Group 28 Noah Walcutt (ME) and Cindy Hlavacek (BME) Advised by Thomas Anderson, MA and Robin Midget

2. What is Sound Therapy? Sound/Music can have therapeutic effects Sound/Music can have therapeutic effects –Emotional well-being & Consciousness –Physical health –Communication abilities –Cognitive skills Evidence in the writings of Aristotle & Plato Evidence in the writings of Aristotle & Plato WWI & WWII WWI & WWII –Musicians visited hospitals across the country playing music for injured soldiers –Veterans said the music helped alleviate the physical and emotional trauma of war

3. Motivation: Potential Benefactors All ages All ages Mental health needs Mental health needs Developmental and learning disabilities Developmental and learning disabilities Alzheimer's disease and other aging related conditions Alzheimer's disease and other aging related conditions Substance abuse Substance abuse Brain injuries Brain injuries Physical disabilities Physical disabilities Acute and chronic pain Acute and chronic pain

4. Project Statement Construct an advanced and unique prototype to be used for sound therapy focusing on: Construct an advanced and unique prototype to be used for sound therapy focusing on: –Electronic operation –Ease of application –Patient & Therapist mobility and comfort

5. How Will it Work? Computer controls magnets which control the guitar strings Computer controls magnets which control the guitar strings Guitar strings create vibrations which resonate the wooden dome Guitar strings create vibrations which resonate the wooden dome Parabolic Dome acts as a sound board for the intensification of vibration inside the base enclosure Parabolic Dome acts as a sound board for the intensification of vibration inside the base enclosure Walls of the enclosure further intensify the sound Walls of the enclosure further intensify the sound Patient sitting underneath dome inside enclosure experiences the generated “music” Patient sitting underneath dome inside enclosure experiences the generated “music” Magnets Strings

6. Initial Design Guitar Strings (4x5=20) ~ 4.5’ Base Enclosure supports Top Dome

7. The Details Electronic Electronic –120V External power source –LabView controls NI 3501 DAC –DAC controls circuit board components for all 20 guitar strings DAC  10kΩ Resistor  Bipolar Transistor  Steady State Relay (SSR)  Solenoid (inductor) (x20) –Solenoids eject magnets that strike guitar strings on dome like piano hammers 4 Guitar Strings DAC Solenoid Boxes Circuit Board

8. Overall Status Still on Schedule ?!

9. Completed Work Course Requirements (up to 1/23/2008) Course Requirements (up to 1/23/2008) Construction of wooden base enclosure and dome with guitar strings/tuners Construction of wooden base enclosure and dome with guitar strings/tuners Construction of complete circuit Construction of complete circuit –On Board: 20x (10kΩ Resistors, Bipolar Transistors, SSRs, and all necessary wire connections to DAQ) –Wire connections between 5 Solenoid Boxes and Circuit Board

10. Current Work Continue researching sound therapy and existing devices Continue researching sound therapy and existing devices Test & Debug electronic construction of striker circuit board and wiring to DAC and solenoid boxes Test & Debug electronic construction of striker circuit board and wiring to DAC and solenoid boxes Complete electronic and mechanical design of strikers to successfully punch guitar strings Complete electronic and mechanical design of strikers to successfully punch guitar strings Modifying wooden base to allow easier testing and manipulation Modifying wooden base to allow easier testing and manipulation

11. Future Work Finalize electronic design & construction of strikers Finalize electronic design & construction of strikers Continue Sound Therapy Research Continue Sound Therapy Research Mechanical Optimization: consistent and reliable string striking Mechanical Optimization: consistent and reliable string striking Write and incorporate LabView software Write and incorporate LabView software Integrate/mount all electronic components Integrate/mount all electronic components Application of Sound Therapy suggested by advisor: Application of Sound Therapy suggested by advisor: –Design moveable walls to utilize more sound space Finishing work: sanding, painting, or coating Finishing work: sanding, painting, or coating Remaining course requirements: reports, presentations, etc Remaining course requirements: reports, presentations, etc

12. What is quality? Test and safely demonstrate the device with the assistance of Robin Midgett and Thomas Anderson, MA Test and safely demonstrate the device with the assistance of Robin Midgett and Thomas Anderson, MA Successful execution of sound therapy principles outlined by Thomas Anderson, MA Successful execution of sound therapy principles outlined by Thomas Anderson, MA –Alter/improve mental state –Monitor Heart Rate, Blood Pressure, Frontal Lobe activity (EEG) Thomas Anderson, MA Rhythimicist – Physics, Drums, Didjeridu, Beat-Box Sound Healing Science – International Consciousness Research Laboratories (ecognosis.org, ICRL.org Robin Midgett Vanderbilt Electronics Technician, Dept of Mechanical Engineering
