What is Sound Therapy?

Sound/Music can have therapeutic effects
–
–
–
–


Emotional well-being & Consciousness
Physical health
Communication abilities
Cognitive skills
Evidence in the writings of Aristotle & Plato
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
Motivation: Potential Benefactors

All ages
Mental health needs
Developmental and learning disabilities
Alzheimer's disease and other aging related
conditions
Substance abuse
Brain injuries
Physical disabilities
Acute and chronic pain
Project Statement

Construct an advanced and unique
prototype to be used for sound therapy
focusing on:
– Electronic operation
– Ease of application
– Patient & Therapist mobility and comfort
How Will it Work?

Magnets



Strings

Computer controls magnets which
control the guitar strings
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
Walls of the enclosure further
intensify the sound
Patient sitting underneath dome
inside enclosure experiences the
generated “music”

The Details
Solenoid
Boxes
DAC
Circuit
Board
– 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 strike guitar
strings
LabView Software – “Key Down”
“Key Up”

Still on Schedule (we think)!
Completed Work



Course Requirements (up to 2/19/2008)
Construction of wooden base enclosure and
dome with guitar strings/tuners
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

Striker box design
Current Work



Continue researching sound therapy
and existing devices
Improve quality of sound generated
Troubleshooting **
Troubleshooting

Dampen noise generated by solenoid
banks
– Rubber, felt, or insulation

Kinematics of strikers
– Modify striker heads

Moveable walls - advantage vs. cost
Future Work





Continue Sound Therapy Research
Mechanical Optimization: consistent and reliable string striking
Modify LabView software to program music
Integrate/mount all electronic components (solenoid
boxes and circuit board)
Application of Sound Therapy suggested by advisor:
– Design moveable walls? Cost Benefit Analysis
 Finishing work: sanding, painting, or coating

Remaining course requirements:
reports, presentations, etc
What is quality?

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
– Alter/improve mental state
– Monitor Heart Rate, Blood Pressure, Frontal Lobe activity (EEG)
