Question | Answer |
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. |
