29 of The intensity of a sound is given by 1 = 1 10:, where L is the loudness of the sound as measured in decibels and lo is the minimum intensity detectable by the human ear. a) Find I, in terms of lo, for the loudness of a small engine, which is 60 decibels. b) Find I, in terms of lo, for the loudness of a quiet sound, which is 10 decibels 15 of 1 c) Compare your answers to parts (a) and (b) d) Find the rate of change di/dl e) Interpret the meaning of di/dL. 14 of 14 a) 1 = 1(Type your answer using exponential notation.) 22 of 22 q b) 1= 1(Type your answer using exponential notation) c) Compare your answers to parts (a) and (b) 20 of 20 qu O A. The small engine is 104 times louder than the quiet sound 21 of 21 ques O B. The small engine is the as loud as the quiet sound. O C. The small engine is 10 times louder than the quiet sound di d) 1 = 10 e) Interpret the meaning of di/dL O A. di/dL is the rate of change in loudness based upon the sound's frequency Next
