## Homework Statement

Imagine a choir of 10 singers, all of different frequencies, but each singing at the same decibel level β if heard

separately. Suddenly one gets bashful and stops singing. By how many decibels does the sound of the full choir drop?

## Homework Equations

I = I1 +I2 + I3 ...

β = 10log10(I/Io)

Io = 1.0 * 10^-2

## The Attempt at a Solution

can i just call the combined decibel level of 10 singers x

x = 10log10(10I/(10^-2)

then call the combined decibel level of 9 singers y

y = 10log10(9I/10^-2)

then subtract them, i have a feeling there is not enough information to solve this :(
