  2. What is SOUND? -Sound is a type of energy - Vibrating objects (such as instruments) cause particles to move and bump into neighbouring particles which begin to vibrate -Vibrating particles create a sound wave which will continue until there is no more energy left

  3. What about waves now? • Waves have two major areas called compressions and rarefactions or high and low pressure areas • Each sound wave has its own wavelength which will repeat continuously • The wavelength and the speed of the sound wave determine the frequency • The amplitude determines how loud the sound will be

  4. What about waves now? In general, a longer wavelength will have a lower pitch and a sound wave with a greater amplitude will be louder. (Hollis, n.d.)

  5. Interference • Interference is when two waves meet • Two types of interference: constructive and destructive • Constructive interference occurs when two sound waves join together so that the peaks and the troughs of one wave are added to the peaks and the troughs of the other wave • Destructive interference occurs when two sound waves join together in a way that the peaks of one wave add to the troughs of the other wave

  6. Constructive interference results in louder sound whereas destructive interference results in the exact opposite. (Hollis, n.d.)

  7. Key Terms • Wind instruments use standing waves • String instruments use transverse waves • Fundamental: the longest possible wave that can fit in a tube or that can be produced by the instrument • Overtones: All other waves that can fit that are also multiples of the fundamentals

  8. -Every instrument has its own overtones -The songs chosen for the exhibit were split into their various parts based on the different instruments • This increased the vibrations

  9. How do we hear? • Ears • Direct sound into inner ear • Detect air pressure change • Transform these changes into the language of the brain (electrical signals)

  12. How do deaf people ‘hear’? • "The perception of the musical vibrations by the deaf is likely every bit as real as the equivalent sounds, since they are ultimately processed in the same part of the brain." Dr. Dean Shibata, assistant professor of radiology at the University of Washington

  13. What do we know? • We know that every instrument creates ‘vibrations’ in different waves (plucking of strings, blowing through a tube, etc.) which deaf people are able to sense • We also know that deaf people are able to enjoy music, as they rely on the vibrations given off by the music to “hear”

  14. What is our exhibit?

  15. Aim/Goal of our Project • The exhibit uses vibrations that actually form sound • OUR MISSION: To allow visitors to view music in a different way. • THEIR CHALLENGE: To figure out what genre of song they are “feeling” through the vibrations.

  16. Exhibit Walkthrough

  17. Technical Aspect • 30-40 second sections of the instrumental tracks of the songs were split into the Lead (guitar or piano), Secondary (bass or deeper piano), and Rhythm (drums or louder piano) using Guitar Pro 5 • Tracks were optimized for maximum vibrations using Audacity
