Chapter 6 (page 155) and Appendix A (page 557), The "EPR" formula didn't print/render correctly. See below for corrected formula:
Chapter 6 (page 168, 2nd Edition & page 166 1st Edition), In both editions there are inaccurate conclusion statements within the section "Microphone Pre-Amp Gain" made with respect to the "Dynamic Microphone A" and "Condenser Microphone B" examples. See following corrections:
For paragraph starting with "Assuming you have a 60 dB gain..." replace last sentence "You need 83.5 dB, but you have only 74.29 dB gain, leaving you 9.21 dB short." with "You need a signal level of -60dB or greater, but you only have a level of -74.29dBu, leaving a 14.29dB shortfall."
For last paragraph in the microphone pre-amp gain section, replace first sentence "With a pre-amp gain of -54.79 dBu, Condenser Microphone B is sensitive enough for this application." with "With a pre-amp having 60dB maximum gain, condenser microphone B with a signal level of -54.79dBu, is sensitive enough for this application, with 5.21dB to spare."
Chapter 6 (page 178, 2nd Edition & page 176 1st Edition), In both editions of CTS-D Exam Guide, the EAD (Equivalent Acoustic Distance) chart shown in Figure 6-25 should include/note "(+ 25 dB S/N)" in the Y Axis label/description.
