(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)

The best definition of limit of detection is:a. The smallest signal that can be detected.b. The most sensitive measurement.c. The smallest concentration that generates a signal that can be confidently distinguished from the blank measurement.d. Anything smaller than 10 ppb.

Compare the values below. Which is greater, or are the two values equal? A. Size of receptor potential in a hair cell during a weak (quiet) stimulus. B. Size of receptor potential in a hair cell during a strong (loud) stimulus. O A is greater than B O B is greater than A O the values are equal
