Decibel / Intensity Problem, How do I approach it? ASAP.!

I have a question, I don't know how to approach it.. I couldn't find a way..

1.Suppose that the sound level of a conversation is Initially at an angry 70 dB and then drops to a soothing 50 dB. Assuming that the frequency of the sound is 500 Hz, determine,

a. Initial and final sound intensities
b. Initial and final sound wave amplitude.?

Can anyone help me please..:cry:
 
Physics news on Phys.org
I know that... But...i mean is theer any inverse log? I don't see in my calculator?
 
Now that you have seen some useful theory... What have you tried so far? You need to show some work before you will see a deluge of helpful hints on the forum. :wink:
 
Yes sir, I did tried. But when I do...It coems to a point where I have to take inverse of log... and I don't think there is inverse function for log..
Or is there? If yes how to do in calculator?
Or am i on wrong way?
 
loga x = y <=> ay = x
