Claim 9:
10. A system for evaluating an electronic device, the system comprising:
an acoustic tube; and
a processing unit configured to:
determine a value of a first parameter, wherein the value of the first parameter is indicative of an acoustic impedance of an open end of the acoustic tube;
determine a value of a second parameter, wherein the value of the second parameter is indicative of an acoustic impedance of the open end of the acoustic tube as occluded by the electronic device; and

calculate a value of a third parameter, wherein the value of the third parameter is indicative of an acoustic impedance of the electronic device, based on the value of the first parameter and the value of the second parameter.
