Pure tone audiometry (PTA) is the standard clinical test for diagnosing the severity and the type of hearing loss. For hearing diagnosis, air conduction (AC) and bone conduction (BC) thresholds are determined and analyzed. Typically, the unmasked BC testing is conducted in one ear as the interaural attenuation (IAA) for BC is considered to be 0 dB. In this case report, we demonstrate the usefulness of performing bilateral BC testing to achieve an accurate hearing diagnosis. As found, the IAA for BC could be as high as 15 dB, and the unmasked BC testing should be performed on both ears to avoid misdiagnosis (particularly on the type of hearing loss). Even though PTA is the standard clinical test for hearing diagnosis, it is still imperative to ascertain its results through comparisons with other clinical test findings.
