## Homework Statement

Five trumpet players have a sound intensity level of 75dB. What would be the sound intensity level of 30 such trumpet players? _______dB

## Homework Equations

Increasing the sound intensity by a factor of 10 results in an increase in perceived loudness by approx. a factor of 2.

Beta = (10dB)log

_{10}(I/I

_{0})

Where I

_{0}= 1.0x10

^{-12}W/m

^{2}

## The Attempt at a Solution

I tried finding a ratio and applying that to the 2nd situation but my answers were wrong. Can someone please help me ASAP!

Thank you!
