The 3 dB rule states that a doubling of the distance from a sound source results in a 3 dB decrease in sound level. What is the formula for sound reduction? Sound reduction can be estimated using the inverse square law: dB reduction = 20 * log10 (initial distance / new distance).The decibel system is based on what is called a logarithmic scale. This means that a sound level of 100dB contains twice the energy of a sound level of 97dB. A rise of 10dB in sound level roughly means that the subjective loudness has doubled.
