Please assist me with this problem​

Answer 1

The answer to your question is 90 dB

Explanation:

Data

I = 10⁻³

I⁰ = 10⁻¹²

Formula

Loudness = 10log (
`(I)/(Io)`)

Process

1.- To solve this problem, just substitute the values in the equation and do the operations.

2.- Substitution

Loudness = 10 log
`((10^(-3))/(10^(-12)) )`

3.- Simplify

Loudness = 10log (1 x 10⁹)

Loudness = 10(9)

Loudness = 90
