\[10\log \frac{ I_{rc} }{ I_0 }-10\log \frac{ I{nc} }{ I_0 }\]

what is I/I0

so in this case, I = 110dB/60dB?!?!?!?!?!

\[I_0 = 10^{-12}W/m^2\]

threshold......oh i c

Now solve for \[\frac{ I_{rc} }{ I_{nc} }\]

What do you mean?

You want to compare the intensities, you're given the decibel readings

So you should have a ratio, no units.

Mhm?

You need to know your logarithm rules

|dw:1436314848076:dw|

60

|dw:1436314962935:dw|

so......wait

spit it out Irish!!! :"D

i don't know what do do here....

since |dw:1436315441718:dw|

we want to know how mch is 110dB louder than 60db...

Haaannn????????????????O_O

So now we have \[5 = \log \frac{ I_{rc} }{ I_{nc} } \implies 10^5 = \frac{ I_{rc} }{ I_{nc} }\]

That's intense :o

Please ask if you don't follow something @YumYum247

i don't get how did you get from there to here?!?!?!?

can you help me learn the way i did it?????please

|dw:1436315726234:dw|

I don't know what that is lol

It's best if you do the algebra first then the calculations after

|dw:1436315751186:dw|

|dw:1436315795001:dw|

|dw:1436315857550:dw|

No, that doesn't even make sense

Awwwwnnnnnnn!!! :"(

Haha, well lets go over it again I suppose

ok we have 110dB and 60dB, we want to know how much 110dB is louder than 60dB

ok

yep.

B as beta?

yes

aight...go on!!! :")

good.

ok

so we ply in the numbers into those two separete formulas to get our numbers?!!?!?!?

Our goal here is to get the ratio \[\frac{ I_{rc} }{ I_{nc} }\]

ok but can you just say βnc = 10logIrcI0 and plug in the numbers to get the difference.

Oh ok i got it.....but it's too long.....

i wanted to do all that in 2 steps :"(

Thank you very very much!!!! :")
and thank yo Irish!!! :)

Np :)

:"(
:"|
:")
:"))
:")))
life as it should be!! good night folks!!

stay yum yum!!!

Haha, I agree! You can see the struggle in the faces and then eventually turning into happiness :)

(logIrcI0×I0Inc) how did you get that.....?!?!?!?! Since 10logIrcI0−10logIncI0

how did yo trn two subtracting emtities into multiplication??????

ok. thanks!!

is this really the remainder???????????????????|dw:1436317748361:dw|
