Decibel Scale

< Older | Newer > 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

Accra, Ghana West Africa

Lying in bed in a Hotel in Accra, Ghana.

1:51 AM
There is music in the distance coming from a bar or a car stereo.
54-56 Decibels and when a car goes by, up to 64.

10:00 PM
My Radio Shack Digital Sound Meter was not reading sufficient sound level to read.
0- 50 Decibels, my guess is about 45.

2:00 PM
I turned on the overhead fan, the person below me had the same type of fan on, and the floors are made of wood.
75-77 Decibels

2:28 AM
The music in the distance has stopped.
0- 50 Decibels, my guess is about 40

A man yesterday in the Internet Café used a cell phone as a music player and the whole Internet Café also listened to his music.

The World Loves music, sports, religions, TV and many other sound making activities.

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

I think yesterday was my first experience with the Cell Phone being used as a Music Player. I was not amused, and prevision of the future.

This Radio Shack Sound Meter is great, a wonderful device and a way to say to myself, yes, this is annoyingly loud and know I am not being over-sensitive.
