1 Pure-tone average (PTA) is the average of hearing sensitivity at 500, 1000, and 2000. 2  This average should approximate the speech reception threshold (SRT), within 5 dB, and the speech detection threshold (SDT), within 6-8 dB. Examples of abnormalities include occlusion of the external auditory canal by cerumen or a mass, middle ear infection and/or fluid, perforation of the tympanic membrane, or ossicular abnormalities. 2  Pure-tone air-conduction thresholds are poorer than bone-conduction thresholds by more than 10 dB (see image below).
