L= niveau sonore
I0=1.0*10**-12

L=10*log(I/I0)
I/I0=10**L/10

Pour calculer l'intensite on utilise:
I=(10**-12)*(10**L/10)

Ou on utilise:

I=P/S

I= W*m**-2
P=W
S=m**2

intensite est additive donc I=I1+I2
de 1.0*10**-12 a +infini

le niveau sonore:
  si l'intensite double le niveau 
  sonore ne double pas il prend
  +3
  niveau sonore 0 a 140Db
  

en + : S=4*pi*r**2
