Noise in a quiet room is 500 times as intense as the threshold of sound. what is the decibel measurement for the quiet room?

27 db

Step-by-step explanation:

I₀ = threshold of sound = 1 x 10⁻¹² W/m²

I = intensity of sound in the room = 500 I₀ = 500 x 1 x 10⁻¹² =  500 x 10⁻¹² W/m²

β = Sound level in decibel in the quiet room

Sound level in decibel in the quiet room is given as

β = 10 log₁₀(I/I₀)

inserting the values

β = 10 log₁₀((500 x 10⁻¹²)/(1 x 10⁻¹²))

β = 27 db

c. (3,2,6) is the answer.
