Abstract:

The devices investigated consisted of floatingplate absorbers, floating membranes, viscous blankets, and pneumatic wave mattresses. Results of tests on floating plate absorbers and membranes are not encouraging whereas the viscous blanket and pneumatic wave mattress seem promising. The viscous blanket gave satisfactory attenuation wave lengths up to about twice the blanket length. The performance of the pneumatic wave mattress was slightly below that of the viscous blanket in this range, but exceeded the viscous blanket for wave lengths greater than twice the absorber length. Both units operated satisfactorily for a considerable range of wave lengths. Author
