Abstract: The methods disclosed herein enable calculating otoacoustic emission (OAE) pressure independent of the acoustic load imposed by the ear canal and the OAE probe measurement system, e.g., for hearing tests. The OAE pressure is calculated in a form of either the first outgoing wave at the eardrum, referred as emitted pressure level (PEPL), or as a Thvenin-equivalent OAE source pressure level (PTPL) at the eardrum, as derived from a simple tube model of an ear canal. In both methods the OAE sound pressure level (PSPL), ear canal reflectance (REC), OAE probe source reflectance (RS), and one-way ear canal delay (?) are measured at the entrance of the ear canal with the OAE probe. In contrast to PSPL, both methods result in an emission pressure that is not confounded by the effects of the residual ear canal space or the impedance of the OAE measurement system.
