Symptoms and Diagnosis of Conductive Hearing Loss
In milder cases of CHL, the most common symptom is being unable or having difficulty hearing lower or softer sounds. If CHL does not heal on its own, it may become progressively worse, causing individuals to have difficulty hearing mild pitched or higher pitched sounds.
Symptoms may be limited to loss of hearing. However, those affected by CHL may also experience the following:
