Distance Attenuation Calc vs Decibel calculator Uso e estatísticas

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 Thanks for your support, and do visit nitrio.com for more apps for your iOS devices.
