摘要: 2. A tuning fork test is used to assess the type of hearing loss, whereas a pure tone audiometry (PTA) should be done confirm and document severity HL. In this case, PTA was consistent with profound right HL severe-toprofound left HL, features mixed in at least one ear (Figure 2). PTA, bone conduction had only been on as patient having scalp injury around pinna mastoid. Unfortunately, attenuation for zero, will detect best cochlea. The result cochlea thus shown but we could not which side ear. That why conclusion “mixed ear”. effects explosive acoustic trauma also can via measurement otoacoustic emissions (OAE).4 OAE check movement outer hair cells. Following explosion, cells may damaged, causing disruption production OAE. Answers
