ooh, i see. so basically the power stays the same because it's the same sound source (a bat, in this case), but the intensity becomes a lot less in distance. i understand now, thanks!

Homework Statement How much acoustic power propagates through a spherical surface (sound source in centre) with radius equal to 1.0m? with radius equal to 5.0m? I = 10^-2 W/m^2 r = 1.0m or 5.0m f = 50kHz t = 2.0*10^-3s IL = 100dB Homework Equations I = P/4∏r^2 The Attempt at a...
