CALCULUL NIVELULUI SONOR

CALCULUL NIVELULUI SONOR IN RAPORT CU DISTANTA

Sound level distance damping decibel dB damping calculation calculator change distance versus sound level apps reduction drop dissipation SPL sound transmission loss free field loss sound and distance - decrease drop fall sound over distance versus dB sound different distances attenuation microphone calculator distance level drop ratio dampening - sengpielaudio Sengpiel Berlin  

Calculation of the sound level L2, which is found at the distance r2
Reference distance r1 
from sound source  
m or ft		 Sound level L1
at reference distance r1 
dBSPL
Search for L2
Another distance r2
from sound source  
m or ft		 Sound level L2
at another distance r2
dBSPL		 Sound level difference 
Δ L = L1 − L2
dB
 
Calculate the distance r2, where the sound level L2 is to find.
Sound level L1 
at reference distance r1 
dBSPL		 Reference distance r1 
from sound source  
m or ft
Search for r2
Sound level L2
at another distance r2 
dBSPL		 Another distance r2
from sound source  
m or ft		 Difference of distance  
Δ r = r2 − r1
m or ft

Sound pressure level (SPL) Lp 
dB-SPL		  ↔  Sound pressure p  
Pa = N/m2
Formula 1   Formula 2
Standard reference sound pressure p0 = 20 μPa = 2 × 10−5 Pa ≡ 0 dB
