At a concert By the Who in 1976, the sound level 50 meters from the stag registered 120 decibles. The treshold of pain for the human ear is 90 decibles. Calculate the sound intensity of the Who concert and the sound intenisity of the treshold of pain

I think you need to combine the sound intensity level formula and the inverse square law for this guy.

WILL YOU HELP ME DO THAT

  • anonymous
why inverse square law?

WILL YOU GO STEP BY STEP WITH ME TO OLVE THIS
heisenberg
  • heisenberg
I will try to help, but I am not too sure. But please, take caps lock off.
toxicsugar22
  • toxicsugar22
ok
heisenberg
  • heisenberg
\[Intensity = \frac{Power}{4*\pi*r^2}\]
heisenberg
  • heisenberg
sorry, not 'power' but 'sound wave pressure'
toxicsugar22
  • toxicsugar22
ok
heisenberg
  • heisenberg
to find P, use this: \[P = P_r * 10^\frac{SPL}{20}\] P_r is the reference point
heisenberg
  • heisenberg
SPL = decibel level
toxicsugar22
  • toxicsugar22
ok
toxicsugar22
  • toxicsugar22
will you help further
toxicsugar22
  • toxicsugar22
so i understand
toxicsugar22
  • toxicsugar22
fr next time
heisenberg
  • heisenberg
What don't you understand?
toxicsugar22
  • toxicsugar22
calculaed the intensity of the concert and the pain
toxicsugar22
  • toxicsugar22
can you help
heisenberg
  • heisenberg
yes you can use those two formulas. First calculate the pressure, then you can use that to calculate the intensity.
toxicsugar22
  • toxicsugar22
yes can u supervise me
toxicsugar22
  • toxicsugar22
help
toxicsugar22
  • toxicsugar22
so I plug in 120 for SLP
heisenberg
  • heisenberg
Yes
heisenberg
  • heisenberg
according to wikipedia, P_ref is often regarded as 20 ┬ÁPa in air, so I would use that for P_r
toxicsugar22
  • toxicsugar22
SO IT IS P=20*10(120/20)
toxicsugar22
  • toxicsugar22
IS IT RIGHT
heisenberg
  • heisenberg
yes that'll give you the pressure. then you need to find the intensity from a distance.
heisenberg
  • heisenberg
glad the caps are back.
toxicsugar22
  • toxicsugar22
so i did 20*10 which is 1200
toxicsugar22
  • toxicsugar22
then i did 120/20 which is 6
heisenberg
  • heisenberg
no, there is an exponent there: \[20*10^\frac{120}{20}\]
heisenberg
  • heisenberg
= 20 000 000
toxicsugar22
  • toxicsugar22
i did that and i DID iT WRONG
toxicsugar22
  • toxicsugar22
like i have this website from school and it checks my work and I did it wrong
toxicsugar22
  • toxicsugar22
can u guide me
toxicsugar22
  • toxicsugar22
again
toxicsugar22
  • toxicsugar22
srry to bother you
toxicsugar22
  • toxicsugar22
heisenberg you there
heisenberg
  • heisenberg
what did you get? I get = 636.619772
toxicsugar22
  • toxicsugar22
i got that also
toxicsugar22
  • toxicsugar22
it not right
toxicsugar22
  • toxicsugar22
tAT IS NOT RIGHT HEISENBERG
