The acoustic impedance of a series of closed front fibre samples of densities in the range 40 to 67 kg m -3 was measured by using impedance tube apparatus. These measurements were then compared with the impedance properties predicted by the theories of Kosten and Zwikker. Reasonably good quantitativ
