If a speaker gives a sound intensity of 10^-6w/m^2 at a certain point, what is the sound intensity level beta at that point

60dB

Explanation:

Sound intensity level β = 10log(I/Io)

Where Io= 10^−12 W/m2 is the reference intensity .

I= 10^-6W/m^2

β= 10log(10^-6/10^-12)

β= 10log(10^6)

β= 10×6 × log 10

Where log 10=1

β=60dB

Therefore, sound intensity level β is 60dB
