When you are 1.5 meters away from the speakers at a concert, the sound level is 130 db. How far away should you sit to reduce the level to 70 db? First calculate the db difference then take the square root of that value and multiply by the original distance

+25 = x

step-by-step explanation:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
