# Math Help - Sound Intensity Problem

1. ## Sound Intensity Problem

Sound intensity is measured by the decibel scale
where is a reference intensity. Thus adding 10 decibels to multiplies with 10. Adding 3 decibels multiplies with _______???

2. I got the answer. Never mind. However, if anyone is interested it's pretty self explanatory: 10^(3/10)

$10^{0.3}$

Every one who works with dB's knows the 10dB - an order of magnitude, 3dB a factor of 2, 7dB a factor of 5 for power like units such as intensity.
