0Two atmospheric sound sources \( A \) and \( B \) emit isotropically at constant power. The sound levels \( \beta \) of their emissions are plotted in Fig. 17-37 versus the radial distance \( r \) from the sources. The vertical axis scale is set by \( \beta_{1}=85.0 \mathrm{~dB} \) and \( \beta_{2}=65.0 \mathrm{~dB} \). What are (a) the ratio of the larger power to the smaller power and (b) the sound level difference at \( r=23 \mathrm{~m} \) ?
