      The concept of 3-dB points should be familiar from control and signal processing theory in that it is the standard measure used to characterize bandwidth. The value of 13 dB is a standard detection threshold. Later, we will show that a SNR threshold of 13 dB yields a detection probability of 0.5 on an aircraft type of target. 1 ©2005 M. C ...

      dB = 10Log. 10 (P1/P0) where P0 is a reference power level of 1 picoWatt (10-12 watts). An increase of 3 dB equals a power increase by a factor of 2.0, so an increase by 6 dB or 3+3 db equals 2x2 or 4. In terms of actual watts ,P1, a 60dB sound leads to a sound power of 10-6 watts and 120dB yields 1 watt.
