Question:
Two atmospheric sound sources A and B emit isotropically at constant power. The sound levels F of their emissions are plotted in Figure versus the radial distance r from the sources. The vertical axis scale is set by β1 = 85.0 dB and β1 = 65.0 dB. What are?
(a) The ratio of the larger power to the smaller power and
(b) The sound level difference at r = 10 m?
