Nonsingular Meshless Method in an Acoustic Indoor Problem

An efficiency of the nonsingular meshless method is analyzed in an acoustic indoor problem. The solution assumed form series radial bases functions. Hardy’s multiquadratic functions, as bases, are taken into account. room field with uniform, impedance walls considered. representative, rectangular cross section chosen. Practical combinations of acoustic boundary conditions, expressed through absorption coefficient values, classical formulation problem used. It established any functions depend on number influence points, frequency and coefficient. All approximate results calculated relation to exact ones. This way, it proved that meshless method based simple efficient description complicated problems for low medium ranges frequency.
