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
change in dB = 10 log base ten (intensity ratio)
= 10 log (100)
= 10*2
= 20 db for ten times intensity
so 80 dB each
Just TEN cars
10 log 10 = 10
so ten dB for 10 times intensity
so
90 db each
To determine the average sound level for each car, you need to divide the total sound level (in decibels) by the number of cars. In this case, there are 10 cars and the total sound level is 100 decibels.
So, if you divide 100 decibels by 10 cars:
100 decibels ÷ 10 cars = 10 decibels per car
Therefore, the average sound level for each car is 10 decibels. This means that on average, each car contributes 10 decibels to the total sound level.
