Homework Statement
If I measure a sound intensity of 1.0 at distance R from its source, what intensity would I measure at distance 3R in a free, unbounded space? What is the difference in decibels?
Homework Equations
I know that the equation for this is 10 (log R2/R1)
The Attempt at a...
Thankyou. How would this one be worked out? I am very new to physics so equations are confusing at the moment:
dB = 10 * log( 6.1 x 10-6 W/m2 / 1.0 x 10-12 W/m2) = 68 dB
How would that be inputted into a calculator?
Thank you very much :)
Homework Statement
Determine the decibel rating of the following intensities of sound.
I = 1.0 x 10-5 W/m2
Homework Equations
The equation which relates the intensity of a sound wave to its decibel level is:
dB = 10 * log( I / 1.0 x 10-12 W/m2)
The Attempt at a Solution
dB = 10 * log( 1...
