Decibel Scale
Atakpame, Togo West Africa
May 1, 2007
I have a digital sound meter I am carrying for reference, I purhased at Radio Shack in the USA for about 50 U.S. dollars. The hope to measure the level of sounds around the world. I sort of think in term or No Smoking or Smoking choices. I think any guide would be helpful to explain large source of temporary or regular noise.
The decibel scale is used primarily to compare sound intensities although it can be used to compare voltages.
Decibels Typical sound
0 --- Threshold of hearing
10 --- Rustle of leaves in gentle breeze
10 --- Quiet whisper
20 --- Average whisper
20-50 --- Quiet conversation
40-45 --- Hotel; theater (between performances)
50-65 --- Loud conversation
65-70 --- Traffic on busy street
65-90 --- Train
75-80 --- Factory (light/medium work)
90 --- Heavy traffic
90-100 --- Thunder
110-140 --- Jet aircraft at takeoff
130 --- Threshold of pain
140-190 --- Space rocket at takeoff
