sound waves & calculation of pressure
dear members ,
pl. help me to the calculation of sound pressure from a given 160 desibles.
thanks in advance.
kvram.
if the value of reference for db is
p0=20·10^-6 pa
then the equation that gives p from the level of pressure in db (=150) is
150=20·log(p/p0)
that solved gives
p=632.465 pa
or
p=6.449·10^-3 kgf/cm^2
and 160 db=3000 pa, roughly. grin
cheers
