Deduction of static surface roughness from complex excess attenuation

Nichols, Andrew; Attenborough, Keith and Taherzadeh, Shahram (2011). Deduction of static surface roughness from complex excess attenuation. Journal of the Acoustical Society of America, 129(3) EL89-EL93.



Data for complex excess attenuation have been used to
determine the effective surface admittance and hence characteristic roughness size of a surface comprising a random distribution of semicylindrical rods on an acoustically hard plane. The inversion for roughness
size is based on a simplified boss model. The technique is shown to be effective to within 4%, up to a threshold roughness packing density of 32%, above which the interaction between scattering elements appears to exceed that allowed by the model.
