  1. Welcome…

  2. “Sound… It’s All Around Us” How to Design for Optimal Workplace Acoustic Comfort

  3. Quiz 1 of 5 What is the difference between sound and noise?

  4. Quiz 1 of 5 “ Noise is unwanted sound , judged to be unpleasant, loud or disruptive to hearing”

  5. What is Sound & Why Does it Matter? Sound affects us in 4 ways… Physiologically Cognitively Psychologically Behaviorally

  6. What is Sound & Why Does it Matter?

  7. What is Sound & Why Does it Matter?

  8. Sound… But what is acoustic design? Sound is measurable Sound is manageable

  9. How We Measure Sound: Reverberation Time “RT (Reverberation Time) is the time for the sound to die away to a level of 60 decibels below its original level.”

  10. How We Measure Sound: RT Norms

  11. How We Measure Sound: Sound Absorption Classifications

  12. How We Measure Sound: Materials

  13. How We Measure Sound: Decibels “ A dB (Decibel) is the unit used to measure the intensity of sound.”

  14. How We Measure Sound 20 dB – Whispered conversation 45 dB – Occupied office 50 dB – Occupied classroom 65 dB – Gymnasium/restaurant 70 dB – Factory/railway carriage 90 dB – Traffic/machinery 110dB – Rock concert 120 dB – Plane at take-off 140 dB -Gunshot

  15. How We Measure Sound 55dB is NOT 10% more than 50dB!
