Fluidic sound absorption and noise insulation in pipelines.

Summary

From measuring results empirical relations are derived for fluidic sound absorption in straight pipelines and the noise insulation of the pipe wall. It is shown that sound absorption in the fluid increases with kinematic viscosity and frequency. The noise insulation level of a pipeline is governed by its geometric variables and the fluid parameters, with the spectral minimum depending on the pipe diameter-wall thickness ratio.
