(Human physiology)

Hearing B is characterized by conductive hearing loss caused by an ear infection or blockage that interferes with the transmission of sound to the inner ear.
Why does this patient hear bone conduction sound with lower intensity than other patients? (Should this disease reduce the sensitivity of sound perception?)

Between A, C and D, which patients had neurological hearing damage causing overall reduction in hearing acuity and which patients had damage caused by an air horn? Why?

(sorry for my bad english)

An audiometry exam tests a subject's ability to hear sounds at different frequencies. Sound waves travel
to the inner ear through the ear canal, eardrum, and the bones of the middle ear (air conduction, empty
circles (0) or alternatively, through the bones around and behind the ear (bone conduction, full dots ().
Figure 1. shows the lowest sound intensity (in dB) at a given frequency (Hz) the test subject can still
perceive, where a 0 value is the population average and any positive value suggests that a higher than
average intensity is required for the subject to hear the sound.
