Claim Text:
1. An apparatus for the objective evaluation of hearing through brain responses or steady state auditive potentials, comprising: means for simultaneously providing a patient with different stimuli through electro-acoustic transducers for both air and bone conduction modes; means for synchronous recording of the neuroelectric activity of the patient, further comprising first and second audio channels, said stimuli comprise a first stimulus comprising one or several mixed low frequencies, amplitude modulated, carrier tones with a M1 modulation frequency through the bone transducer and first audio channel, and the second stimulus comprises one or several mixed high frequencies, amplitude modulated, carrier tones with a M2 modulation frequency through the airway transducer and second audio channel, with synchronous recording of the neuroelectric activity caused by the simultaneous bone and airway stimulation; and means for processing and analyzing the neuroelectric activity to obtain a result of the primary hearing test for classifying, the hearing disorder as a conductive or sensorineural disorder.
