1. Question Details The noise from a power mower was measured at 101 dB. The noise level at a rock concert was measured at 122 dB. Find the ratio of the intensity of the rock music to that of the power mower. (Round your answer to the nearest whole number.) 2. Question Details A law of physics states that the intensity of sound is inversely proportional to the square of the distance d from the source: I = k/d. (a) If B1 is the decibel level at a distance d1, use this model and the equation B = 10 log To (described in this section) to find the equation for the decibel level By at a distance d2 relative to B1 and d1. By = (b) The intensity level at a rock concert is 116 dB at a distance 2.5 m from the speakers. Find the intensity level at a distance of 10 m. (Round your answer to the nearest whole number.) B2 = dB
