Extracted text: The intensity of sound is measured in watts per square meter. Normally this is given as a relative intensity.t Loudness of sound is measured in decibels, and the number of decibels is 10 times the logarithm of the relative intensity: Decibels = 10 log(relative intensity) (a) In this part assume that four stereo speakers, each producing 37 decibels, are placed side by side, multiplying by a factor of 4 the relative intensity of sound produced by only one of the speakers. What is the decibel level of the four speakers together? (Round your answer to the nearest whole number.) decibels (b) Find an exponential formula giving relative intensity I as a function of decibel level D. I = (c) What is the growth factor for relative intensity as an exponential function of decibels? Reminder: aE = (a . (Round your answer to two decimal places.) %3D
