First - a point source of sound in free space (air on all sides) and that emits power isotropically (in all directions) will see power diminish with distance (since the "sphere" of sound gets bigger, the sound at any one point on that sphere must have less energy). This results in a decrease of 6 dB every time you double the distance.
Sound Attenuation | Unreal Engine Documentation

This property defines the distance directly behind the sound's origin from where you want the cone to start (this is independent from the other properties, so will extend the cone backward …

The sound attenuation formula is. SPL₂ = SPL₁ - 20 * log (R₂ / R₁) Where, SPL₁ is the sound pressure level at the point 1. SPL₂ is the sound pressure level at point 2. R₁ is the distance from the sound source to point 1. R₂ is the distance from the sound source to point 2.

Sound Attenuation Calculator - Inverse Square Law. The formula to calculate sound attenuation over distance for a point source is: Lp (R2) = Lp (R1) - 20·Log10(R2/R1) Where: Lp (R1) = Known sound pressure level at the first location (typically measured data or equipment vendor data) Lp (R2) = Unknown sound pressure level at the second location Location.
What is Distance Attenuation and how does it work?
https://www.acoustical.co.uk/distance-attenuation/distance-attenuation/
Distance attenuation is defined as the way in which a sound level reduces as a listener moves away from a sound source. As sound travels from the source, the area over which the sound is spread increases like ripples on a pond. The way in which the skin of a balloon gets fainter as it is inflated is a good model for the way in which the sound level reduces as the …
Applying Distance-Based Attenuation
https://www.audiokinetic.com/library/edge/?source=Help&id=applying_distance_based_attenuation
Cone attenuation: Influences the intensity of the signal based on the orientation of the emitter in relation to the listener. The distance attenuation is defined using a series of curves. These curves map Wwise property values, such as volume, to a distance value. By defining the properties of each point along the curve, you can control the volume attenuation for objects as they move …
What Is Sound Attenuation? [2022]
https://soundproofsilence.com/sound-attenuation/
There’s sound attenuation, audio attenuation, wave attenuation and noise attenuation. Attenuation means a loss or reduction of intensity or energy. To understand attenuation better, we need to take a look at sound waves and how they work. Nature of sound waves. Sound is said to be a wave phenomenon.
Distance Attenuation: How Sound Reduces with Distance
https://www.acoustical.co.uk/distance-attenuation/how-sound-reduces-with-distance-from-a-point-source/
The area of a surface around a point sound source increases with the square of the distance from the source. This means that the same sound energy from the source is distributed over a larger area and the energy intensity reduces with the square of the distance from the source (Inverse Square Law). For every doubling of distance, the sound level reduces by 6 …

If we know the sound level measured at a certain distance from the source, then we can estimate sound level, that we would observe at a different distance: A ( r ) = A ( r 0 ) − 20 l o g ( r r 0 ) A(r) = A(r0) - 20 ~ log\left(\frac{r}{r_0}\right) A ( r ) = A ( r 0 ) − 20 l o g ( r 0 r )

The sound intensity decreases with the ratio 1 /r2 to the distance. For a cylindrical wave that is a line source we get: The sound pressure level (SPL) decreases with doubling of distance only by (−)3 dB. The sound pressure falls to 0.707 times (70.7%) of the initial value of the sound pressure.
