How loud is a rock concert ?

January 11, 2011

The Decibel (dB) scale measures noise in objective terms.

On the Decibel scale, each 10 points [dB(A)] added represents 10 times as much sound.

For example; 70 dB(A), is not 17% louder, but ten times as loud as 60 dB(A).

  • Threshold of human hearing: 0 dB(A)
  • Soft whisper: 20 dB(A)
  • Refrigerator: 50 dB(A)
  • Normal conversation: 60 dB(A)
  • Dishwasher running: 55-70 dB(A)
  • Busy street traffic: 70 dB(A )
  • Car interior: 75 dB(A)
  • Vacuum cleaner: 80 dB(A)
  • Common home stereo: 80 dB(A)
  • Lawn mower: 90 dB(A)
  • Rock concert: 110 dB(A)
