ABSTRACT:
An acoustical cell for analysis of materials by measuring parameters of acoustical resonanace. The cell comprises a main frame and an electroacoustical transducer assembly. The main frame includes at least one interstice and has substatially parallel exterior surfaces that engage, in use, with walls to define a resonant cavity into which a specimen for analysis is placed in use. The electroacoustical transducer assembly is acoustically coupled to at least one of the walls and comprises at least one electroacoustical transducer.
