    If she has an obstruction in the ear cannal or perforation of the ear drum, then her hearing can be ‘fixed’ by removing the obstruction or putting a gromit in the perforated drum (if there is a small hole). Then by the time she has her third hering test, she may pass.

    If there is a malfunction of the ossicles which transmit the vibration from the tympanic membrane to the oval window, either through some kind of trauma or if it is a genetic condition, then her hearing will not get better and she will not pass the test the third time.

    If there is neural damage, or if the cochlea itself is damaged, called sensorineural deafness, then once again, her hearing will not get better and will not pass the test.

    These hearing tests use tones of different volumes and frequencies to detect deafness in those frequencies. So if there is a general obstruction, then there may be an overall decline in hearing across all frequencies.

    Hope things work out.

    There are different types of hearing tests.
    Newborns in the US are typically screened by ABER, which is a test measuring whether the auditory nerve is functioning at the level of the brainstem. Other tests measure where problems lie within the auditory tract and perception centers.
    Direct your questions to the pediatric ENT or the audiologist. The answers you seek on YA are too detailed to discuss here.
