Acoustic properties

Various acoustic properties are displayed on this page such as the columns headed Z.re and Z.im which are the real and imaginary parts of the acoustic impedance of the given thickness of material backed by a rigid surface and the columns headed G.re and G.im which are the real and imaginary parts of the propagation constant. The column marked An is the normal incidence absorption coefficients, the column marked Ae is the random incidence absorption coefficients. The column headed TL is the transmission loss of the inner layer of material.

You can also highlight these values using the cursor and copy them to the clipboard using the button in the bottom right corner.

Reference spectra can be added by clicking to paste data into the Table. Reference spectra data can also be typed into the ZORBA Table directly
