For example, the difference in the DTV signal level at the noise-limited contour of a 1 MW, 500m high transmitter at 135 km (see 22-06-0052-03-0000_WRAN_Keep-out_Region.xls) for F(50,90) and F(50,50) is found to be 5.91 dB. The standard deviation is therefore 4.61 dB.

As can be seen from figure (5), the 900 Hz was primarily affected by sea state, while both distant shipping and sea state impacted 400 Hz. Based off of the shipping density chart (figure (6)) and the UDAS measured wind speed (figure (7)), static ambient noise estimates values for 400 and 900 Hz were 65 dB and 61 dB, respectively.

Every individual noise measurement shall be evaluated. The sound level of every specified measurement point shall not exceed the limits given below: Lkj ≤ LASEP_k.j + 2 dB(A) If the measured noise level at a point exceeds the limit, two additional measurements at the same point shall be carried out to verify the measurement uncertainty.

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.

At 75 dB, intelligibility is down to 4% with a normal voice. Figure 4. Figure 5 is a table of values illustrating outdoor communications at various distances with a normal and raised voice7. Note that when the steady-state ambient noise level is 72 dBA, normal voice communication is only 0.5 metres (~20 inches).
