Research Abstract |
Prediction method using the finite-difference time-domain method for floor impact noise was proposed. The method can deal with heterogeneous and anisotropic media including wooden materials. Software with a graphical user interface was also developed for nonprofessionals to practically predict the noise using graphic processing units.
