9               Factors that must exist
At least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting conductive hearing loss or death from conductive hearing loss with the circumstances of a person's relevant service:
(1)          having otosclerosis on the affected side at the time of the clinical onset of conductive hearing loss;
(2)          having a disease from the specified list of bone diseases, involving the conductive hearing apparatus of the affected side, at the time of the clinical onset of conductive hearing loss;
Note:  conductive hearing apparatus and specified list of bone diseases are defined in the Schedule 1 - Dictionary.
(3)          having osteoporosis at the time of the clinical onset of conductive hearing loss;
(4)          having an episode of otitic barotrauma involving the affected ear, within the seven days before the clinical onset of conductive hearing loss;
(5)          being exposed to a peak sound pressure level at the tympanic membrane of at least 140 dB(C), within the seven days before the clinical onset of conductive hearing loss;
Note: dB(C) is defined in the Schedule 1 - Dictionary.
(6)          being exposed to an explosive blast within the seven days before the clinical onset of conductive hearing loss;
(7)          being struck by lightning within the seven days before the clinical onset of conductive hearing loss;
(8)          having blunt trauma, penetrating trauma or surgery, involving the conductive hearing apparatus of the affected ear, within the seven days before the clinical onset of conductive hearing loss;
Note: conductive hearing apparatus is defined in the Schedule 1 - Dictionary.
         (9)          having acquired, permanent narrowing or obstruction of the external auditory canal of the affected ear, at the time of the clinical onset of conductive hearing loss;
             Note 1:  Examples of causes of narrowing or obstruction of the external auditory canal include, but are not limited to:
                (a)        benign fibro-osseous lesion;
                (b)       benign or malignant neoplasm;
                (c)        chronic otitis externa;
                (d)       exostosis of the external auditory canal;
                (e)        granuloma; and
                (f)        necrotising otitis externa.
Note 2:  exostosis of the external auditory canal is defined in the Schedule 1 – Dictionary.
(10)      having chronic otitis media, involving the middle ear of the affected side, at the time of the clinical onset of conductive hearing loss;
Note: chronic otitis media is defined in the Schedule 1 - Dictionary.
(11)      having:
(a)          a benign or malignant neoplasm; or
(b)          other mass lesion;
         involving the middle ear of the affected side, at the time of the clinical onset of conductive hearing loss;
            Note: Examples of neoplasms or mass lesions involving the middle ear include, but are not limited to:
              (a)                       cholesteatoma;
              (b)       granuloma; and
              (c)         neuroendocrine
