#0,00158W//m^2#

Explanation:

Sound level #beta = 10log(I/(I_0))#, where #I_0# is the threshold or reference intensity corresponding to the minimum sound that a normal human ear can hear and is assigned a value of #10^(-12) W//m^2#

So in this case, #92=10log(I/(10^(-12)))#

#therefore I=10^(9,2)*10^(-12)=10^(-2,8) W//m^2#
