Decibels are in essence a measure of volume. The volume or intensity of sound is measured in units called decibels (dB), generally on a scale from zero to 140 (any higher than 140 and you are in trouble immediately). The higher the number in decibels, the louder the noise. The louder the noise, the greater the risk of hearing loss.
The logarithmic decibel scale is convenient calculating sound power levels for two or more sound sources. Adding Equal Sound or Noise Power Sources. Adding Equal Sound Power Calculator. Note! Adding of two identical sources will increase the total sound power level with 3 dB (10 log(2)). Sound power and sound power level are often used to specify the noise or sound emitted from technical equipment like fans, pumps or other machines. Sound measured with microphones or sensors are sound pressure.
