1. An audiometer for testing the hearing of a test subject, the audiometer comprising:

  • an audiometer module including a test signal generator and a processor with associated memory and control logic operably coupled to the test signal generator, wherein the processor controls the test signal generator to generate an electronic test signal having a first signal magnitude, wherein the processor further controls the test signal generator to adjust the first signal magnitude to a second signal magnitude in proportion to a transducer correction value and to deliver the electronic test signal with the second signal magnitude at an output of the audiometer module;

    a transducer communicatively coupled to the output of the audiometer module, wherein the transducer generates a sound signal having a desired magnitude when the electronic test signal having the second signal magnitude is delivered to the transducer, wherein the transducer further comprises a data storage structure, and wherein the transducer correction value is stored by the data storage structure; and

    an interface selectively couplable with the processor for delivering the transducer correction factor to the processor.
