Abstract: An audiometer including a processor controlled test signal generator is adjustable so as to produce a uniform output signal when coupled with a transducer load. Each transducer set to be used with the test signal generator includes recordable indicia in written or electronic form, upon which correction values for adjusting the electronic signal output of the audiometer module to produce a desired sound output from the each transducer in the transducer set. When the transducer set is connected to the audiometer module, the correction values are either retrieved automatically from the electronic indicia, which may be an EEPROM, or are input to the processor manually by a user through an interface such as a keyboard. These correction values are then used by the processor to dynamically adjust the output of the audiometer to correct for sound output response deviation of each transducer in the transducer set.
