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

Best ResponseYou've already chosen the best response.0I think you need to combine the sound intensity level formula and the inverse square law for this guy.

Best ResponseYou've already chosen the best response.0\[Intensity = \frac{Power}{4*\pi*r^2}\]

Best ResponseYou've already chosen the best response.0sorry, not 'power' but 'sound wave pressure'

heisenberg

Best ResponseYou've already chosen the best response.0to find P, use this: \[P = P_r * 10^\frac{SPL}{20}\] P_r is the reference point

Best ResponseYou've already chosen the best response.0calculaed the intensity of the concert and the pain

heisenberg

Best ResponseYou've already chosen the best response.0yes you can use those two formulas. First calculate the pressure, then you can use that to calculate the intensity.

Best ResponseYou've already chosen the best response.0so I plug in 120 for SLP

heisenberg

Best ResponseYou've already chosen the best response.0according to wikipedia, P_ref is often regarded as 20 µPa in air, so I would use that for P_r

Best ResponseYou've already chosen the best response.0SO IT IS P=20*10(120/20)

heisenberg

Best ResponseYou've already chosen the best response.0yes that'll give you the pressure. then you need to find the intensity from a distance.

Best ResponseYou've already chosen the best response.0so i did 20*10 which is 1200

toxicsugar22

Best ResponseYou've already chosen the best response.0then i did 120/20 which is 6

heisenberg

Best ResponseYou've already chosen the best response.0no, there is an exponent there: \[20*10^\frac{120}{20}\]

toxicsugar22

Best ResponseYou've already chosen the best response.0i did that and i DID iT WRONG

toxicsugar22
