NAL-N1, RECD, & REAG: Accurate and Practical Methods for Fitting Non-Linear Hearing Aids to Infants and Children

It is well accepted that the hearing aid prescription procedure for infants and young children should be based on real-ear aided gain (REAG) rather than insertion gain (REIG). A procedure based on REAG prescribes the same gain from the free field to the eardrum for the same degree of hearing loss, irrespective of the gain provided by the unaided ear canal. This paper focuses on the implementation of NAL-NL1 in fitting hearing instruments to children using a REAG approach that incorporates the measurement of individual real-ear-to-coupler difference (RECD).
