-The default value of 31.67 mW (65 dB re 10e-12 Watts) corresponds to 1 Pascal (94.0 dB SPL re 20e-6 Pascal ) in a distance of 1 m for spherical spreading. The final gain of a sound source is linked to the input signal, which is explained below. However, a digital signal with an RMS value of 1.0 (e.g., a sine wave with peak value of sqrt(2)) will retain 94 dB SPL @ 1m. A directivity may alter this value for a certain direction, but a calibrated directivity will not change the overall excited sound power of the sound source when integrating over a hull. +The default value of 31.67 mW (105 dB re 10e-12 Watts) corresponds to 1 Pascal (94.0 dB SPL re 20e-6 Pascal ) in a distance of 1 m for spherical spreading. The final gain of a sound source is linked to the input signal, which is explained below. However, a digital signal with an RMS value of 1.0 (e.g., a sine wave with peak value of sqrt(2)) will retain 94 dB SPL @ 1m. A directivity may alter this value for a certain direction. Here, two approaches are common. A power calibrated directivity database will not change the overall excited sound power of the sound source when integrating over a hull, which may influence the spectrum to the front. A referenced directivity will not affect the spectrum of reference direction, usually the front - the frequency values all become 1.0 (0 dB).
