<u>Solution-</u>
Given that, loudness measured in dB is

Where,
I = Sound intensity,
I₀ = 10⁻¹² and is the least intense sound a human ear can hear
Given in the question,
I₁ = Intensity at Brandon's = 10⁻¹⁰
I₂ = Intensity at Ahmad's = 10⁻⁴
Then,



C because 6 times 8 is 48 which is greater than 42
