Noise-source mechanisms for the simple fluid valve model were observed and compared with predicted mechanisms. A comparison of the predicted mechanisms with the experimental data indicated that the scaling laws could be further improved by a re-examination of the influence of the impact parameters. This was done by an extended analysis of the influence of geometrical parameters on acoustical characteristics. Additional parameters were determined statistically using nonlinear multiple regression analysis of the experimental data. The estimated correlation between the observed and predicted values for the applied geometrical and hydrodynamic parameters are good. [S0739-3717(00)01303-9]
