What It Is. Sound pressure level - SPL decreases 6.02 dB as a listener's distance doubles from the sound source. This number is commonly rounded down to 6 dB. The opposite is true as the listener halves the distance to the source, so that the SPL decreases or increases by 6 dB with every distance doubling or halving, respectively. The Inverse Square Law is used to calculate …
What is "Inverse Square Law"?
https://www.sweetwater.com/insync/inverse-square-law/
Inverse Square Law. Useful when setting up a microphone or speaker, the inverse square law states that, in a free field the intensity of sound drops by 6 dB for each doubling of distance from the source. Now, none of us ever work in a truly free field (no reflective surfaces), but for most applications these numbers are accepted as workable. In real world terms, this …
Inverse Square Law for Sound - Georgia State University
http://hyperphysics.phy-astr.gsu.edu/hbase/Acoustic/invsqs.html
Sound from a point source obeys the inverse square law. It's intensityin decibelscan be calculated by comparing the intensity to the threshold of hearing. At a distance r = m = ft. from a point source of acoustic power P = watts. the sound intensity is x10^ watts/m2= dB. Decibel definition. Decibel calculation. Calculating dB for distance ratios.

The sound intensity is the product of the RMS sound pressure and the in-phase component of the RMS particle velocity, both of which are inverse-proportional. Accordingly, the intensity follows an inverse-square behaviour: I \ = \ p v \ \propto \ \frac{1}{r^2}.
Sound Attenuation – Inverse Square Law - WKC Group
https://www.wkcgroup.com/tools-room/inverse-square-law-sound-calculator/
In terms of the propagation and attenuation of sound, the inverse square law is a principle in physics whereby a point source emits a sound wave uniformly in all directions (essentially spherically), where the intensity of the sound wave energy at any given point away from the source is diminished as a function of the total surface area of the sphere coincident with that …
Estimating Sound Levels With the Inverse Square Law
http://hyperphysics.phy-astr.gsu.edu/hbase/Acoustic/isprob2.html
the inverse square law predicts a sound level. I2= dB. You can explore numerically to confirm that doubling the distance drops the intensity by about 6 dB and that 10 times the distance drops the intensity by 20 dB. Decibel definition. Decibel calculation.
