What are the examples of the damage of inner ear and middle ear and can we correct it？

An electrocochleography (ECog) test is done to measure the electrical activity in the inner ear. An auditory brainstem response (ABR) test checks the function of the hearing nerves and the hearing center in the brain. These tests can tell your doctor if the problem is caused by your inner ear or with your ear nerve.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
