smells
what kind of deafness occurs when there is damage to the middle ear which affects the loudness of sounds? * 1 point
sensorineural
frequency
conductive
cochlear

Explanation:

1. Sound is produced by vibrations that cause changes in air - pressure waves which our ears detect.
2. Conductive deafness occurs when there is damage to the middle ear, affecting the transmission of sound and thus the loudness perception. Sensorineural deafness is related to damage in the inner ear or auditory nerve, frequency is a characteristic of sound waves, and cochlear is related to the inner - ear structure but not the type of deafness related to middle - ear damage.

Answer:

1. A. Sounds
2. C. Conductive
