Parametri di propagazione sonora in corpi assorbenti granulosi

  • Published:
Il Nuovo Cimento (1943-1954)

Riassunto

Sono state eseguite misure di impedenza acustica su materiali assorbenti granulosi (pallini di piombo e sabbie di varia granitura), deducendo i parametri primari di propagazione sonora. I risultati ottenuti sperimentalmente vengono confrontati con dati teorici.

Summary

Measurements of acoustical impedance of granular absorbent materials are described (small leaden balls and sand of various size); the parameters of sound propagation are deduced. Then the experimental results are compared with theoretical data.
