System and methods for conducting multiple diagnostic hearing tests

A system for conducting an audiometric hearing test and a second hearing test selected from the group consisting of an otoacoustic emission hearing test and an acoustic immittance hearing test in a first ear of a patient, said system comprising:

• a first insertion probe comprising a sealing surface for engaging the external auditory canal of said first ear and providing an airtight seal within said canal;
• a first transducer for providing to said first ear through said insertion probe an audiometric test sound and an acoustic immittance test sound;
• a second transducer for receiving from said first ear through said insertion probe a second hearing test result sound comprising an acoustic immittance test result sound;
• and
• a third transducer for receiving an otoacoustic emission sound.

A system for conducting an audiometric threshold hearing test, a tympanogram hearing test, an acoustic reflex hearing test, and an otoacoustic emission hearing test in a first ear of a patient, said system comprising:

• A) an insertion probe comprising a seal for providing an airtight seal within the external auditory canal of said first ear;
• B) at least one speaker for providing to said first ear though said insertion probe an audiometric test sound, a tympanogram test sound, an acoustic reflex test sound, and an otoacoustic emission test sound;
• C) a first microphone for receiving from said first ear though said first insertion probe a tympanogram test result sound and an acoustic reflex test result sound;
• D) a second microphone for receiving an otoacoustic emission sound from said first ear though said insertion probe;
• and
• E) a reversible air compressor for delivering air to and removing air from said first ear through said insertion probe.
