What is the difference between sound and noise?
SLIDE 4
Quiz 1 of 5
“Noise is unwanted sound, judged to be unpleasant, loud or disruptive to hearing”

Sound…
But what is acoustic design?
Sound is measurable Sound is manageable
SLIDE 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.”
SLIDE 10
How We Measure Sound: RT Norms
SLIDE 11
How We Measure Sound: Sound Absorption Classifications
SLIDE 12
How We Measure Sound: Materials
SLIDE 13
How We Measure Sound: Decibels
“A dB (Decibel) is the unit used to measure the intensity
- f sound.”
SLIDE 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
SLIDE 15
How We Measure Sound
55dB is NOT 10% more than 50dB!
