Ddetect = 3.16 m Submit Previous Answers ✓ Correct Part B In general, if a sound has intensity of 3 dB at 1 m from the source, at what distance de from the source would the decibel level decrease to 0 dB? Since the limit of hearing is 0 dB this would mean you could no longer hear it. Express the distance in terms of B. Be careful about your signs!
