  • Accommodates precision up to 16 decimal places
  • Supports multiple units for diverse input parameters

Distance attenuation is fundamentally the reduction of sound level in dB as an observer moves further away from a sound source. As sound propagates, it radiates outward, causing the energy to be distributed over an increasing area, much like ripples spreading across water. Consequently, this dispersal leads to a decrease in sound intensity as the distance from the source increases.

The formula governing sound attenuation is outlined as follows:

SPL₂ = SPL₁ - 20 * log (D₂ / D₁)

Where:

  • SPL₁ - Sound Pressure Level [dB] at point 1
  • SPL₂ - Sound Pressure Level [dB] at point 2
  • D₁ - Distance from the sound source to point 1
  • D₂ - Distance from the sound source to point 2
