| Abstract: | Sound experiential formulae are applied widely in sing beam and multibeam echo sounder. The precision sound formula is very important for high accuracy height determined in hydrography by sounder. There are many experiential sound speed formulae now. It is necessary to look for a classic experiential sound speed formula as standard. For this aim, in this paper, respective sound speed and its changing rate in different conditions are calculated. Base on above results, analyses and statistics are done in this paper. A conclusion is obtained that the EM experiential sound speed formula is considered classic. It is adapted to different water layers, salinity and temperature. The conclusion is tested right in shallow water layer, and is hopeful of applying for more deeper water layers. |
