Abstract |
20 models from Poland, Finland, England, USA, USSR, Australia, Hungary, and West Germany were tested. Acoustic efficiency and attenuation power were measured. A rapid method of calculating the attenuation power using a sum of imaginary spectra and a mini-computer is presented. There was a relation between the shape of the attenuation curve and the acoustic efficiency. |
