About Distance Attenuation Calc

The Distance Attenuation Calculator is a physics/math calculator designed to find the sound level in dB decreases with distance from the sound source quickly and easily.

Features:
- Instant calculation
- Results are copyable to other apps
- Formulas are included as reference
- Supports up to 16 decimal places
- Supports various units for each input

Distance attenuation is defined as the way in which a sound level [dB] 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. This means that the same amount of acoustic energy is dispersed over a greater area, and as a result, the sound level at any position on this area reduces as the distance from the source is increased.

Sound attenuation describes how the SPL [dB] changes with increasing distance from the sound source.

The sound attenuation formula is 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
