Which type of hearing problem can be reduced with ordinary hearing aids? central deafness conduction deafness sensory-neural deafness auditory pathway deafness?

The answer is conduction deafness. Conduction deafness occurs when sound waves have difficulty reaching different parts of the ear. Hearing aids can amplify the sound waves or use the bone to conduct sound instead of air. The other choices are caused by damaged structures or differences in the brain. Ordinary hearing aids are ineffective in those cases.
