Sound Wave Project

Summary

The purpose of this project was to create some form of media that simply defines terms relating to sound waves.  I simplified their definitions, then created a song with GarageBand.  The lyrics to the song are the simplified definitions in an order that makes sense and rhymes.  After finishing, everyone in the class shared their projects to drive the terms into memory.

Timeline

Wednesday, Thursday– Plan project, type out blog post.  Begin working on the beat for the song.

Friday– Simplify the terms, begin to create lyrics, continue working on beat.

Monday, Tuesday– Continue working on lyrics and beat.

Wednesday– Finish lyrics and beat, start recording.

Thursday– Record song, final edits.

Terms and the Song

  • Amplitude- Height of the sound wave, related to volume
  • Bass- Range of low notes in sound frequency spectrum
  • Compression- Doesn’t allow the full height of the sound wave
  • Decibel- How loud a sound is
  • Equalization- Boosting or the opposite of boosting certain frequencies
  • Frequency- Number of times something vibrates
  • Fundamental- Lowest sound an instrument can make
  • Harmonic- Octave of the fundamental
  • Hertz- Unit of measurement of frequency
  • Infrasonic- Below sound frequency spectrum, too low to hear
  • Midrange- Middle range of notes in the sound frequency spectrum, easiest for humans to hear
  • Octave- When the wavelength of two notes are half or double of each other, same note in different pitch
  • Phase- The waves hitting each other, two identical waves with different phase shift
  • Pitch- How high or low a sound is
  • Sound Frequency Spectrum- 20 to 20000 Hz, range humans can hear
  • Sound Wave- Vibrational disturbance that creates sound
  • Treble- Range of high notes in the sound frequency spectrum
  • Ultrasonic- Too high to hear, dogs can hear some higher sounds
  • Velocity- How hard the keys are being hit
  • Wavelength- Distance between highest points of the wave, length of period

 

What I Learned

Through the project, I greatly increased my understanding of sound waves, and the terms that relate to them.  I had to plan out my project and stick to the timeline I created prior to starting the project.  This helped me stay on task and get a feel for how complete my project was.  There were several problems with my project, for example when I couldn’t save my voice recording.  I had to spend extra time to remedy this and similar problems, but my timeline let me know whether the problems were putting me behind schedule or not.  In the end I got to practice using GarageBand, learn about sound waves and time management, and I have a finished product I am happy with.
