Ray tracing in a turbulent, shallow‐water channel

Christian Bjerrum‐Niese, René Lützen, Leif Bjo/rno/
1998 Journal of the Acoustical Society of America  
Such an earplug is especially designed against weapon noises ͑up to 190 dB peak͒. The study is based on experimental approach.  ...  The ability to listen to these contributions, also called partial pressures, is needed for the sound quality evaluation of engine noise, and the next logical step in transfer path analysis.  ...  So this method includes a gauging step which consist to calculate the spectrum Sb of a block's echo.  ...
