Question

Ten cars at an intersection are blowing their horns simultaneously, creating a 100 decibel sound in the middle of the intersection. What is the average sound level for each car?

10/100= 10db per car?? Idk

Answer 1

change in dB = 10 log base ten (intensity ratio)

= 10 log (100)

= 10*2

= 20 db for ten times intensity
so 80 dB each

Answer 2

Just TEN cars

10 log 10 = 10
so ten dB for 10 times intensity
so
90 db each
