Hearing Aids - Real Ear Measurement

QuestionAnswer
REUR SPL, as a function of frequency, at a specified measurement point in the ear canal, for a specified sound field, with the ear canal unoccluded.
REUG Difference in decibels between the SPL, as a function of frequency, at a specified measurement point in the ear canal and the SPL at the field reference point, for a specified sound field, with the ear canal unoccluded.
REAR SPL, as a function of frequency, at a specified measurement point in the ear canal for a specified sound field, with the hearing aid (and its acoustic coupling) in place and turned on.
REAG Difference in decibels, as a function of frequency, between the SPL at a specified measurement point in the ear canal and the SPL at the field reference point, for a specified sound field, with the hearing aid in place and turned on.
REIG Difference in decibels, as a function of frequency, between the REAG and the REUG, obtained with the same measurement point and the same sound field conditions. Previously called real-ear insertion response.
REOR SPL, as a function of frequency, at a specified measurement point in the ear canal, for a specified sound field, with the hearing aid (and its acoustic coupling) in place and turned off.
REOG Difference in decibels, as a function of frequency, between the SPL at a specified measurement point in the ear canal and the SPL at the field reference point, for a specified sound field, with the hearing aid in place and turned off.
RECD Difference in decibels, as a function of frequency, between the SPL at a specified measurement point in the ear canal and the SPL in a 2cc coupler, for a specified input signal.
