  • Double or twice the loudness = factor 2 means about 10 dB more sensed loudness level (psycho acoustic)
  • Double or twice the voltage = factor 2 means 6 dB more measured voltage level (sound pressure level)
  • Double or twice the power = factor 2 means 3 dB more calculated power level (sound intensity level)
