specLvlGraph | R Documentation |
This function calculates the ambient noise level (NL; dB re. 1 microPa) in a deep-water marine environement.
specLvlGraph(freqBand, shipT = -1, seaState = -1, wSpeed = 0, boolR = TRUE)
freqBand |
The frequency band of interest |
shipT |
The intensity ship traffic in the area * 1 - 2 low ship traffic * 3-4-5 standard ship traffic * 6 - 7 heavy ship traffic * 8 - 9 intense ship traffic |
seaState |
The sea state as specified by the National Weather Service |
wSpeed |
The wind speed in miles per hour (mph) |
boolR |
Boolean of whether you want the value printed out in a string. Should be true for HW problems. |
The noise level (NL) in dB re. 1 microPa
