Question

At point A, 3.20 m from a small source of sound that is emitting uniformly in all directions, the intensity level is 51.0 dB.

a) What is the intensity of the sound at A? I got

I =

1.26×10⁻⁷

W/m2

and it is correct.

b)How far from the source must you go so that the intensity is one-fourth of what it was at A?

I got

R1

=

6.40

m

and it is correct.

c) How far must you go so that the sound level is one-fourth of what it was at A?

I need help with this question.
