Evaluating the benefit of speech recoding hearing aids in children

Am J Audiol. 2003 Dec;12(2):106-13. doi: 10.1044/1059-0889(2003/018).

Abstract

Children with significant high-frequency hearing loss may be difficult to fit with hearing aids using conventional amplification. Frequency-lowering hearing aids using dynamic speech recoding (DSR) technology have been proposed as a possible means to achieve full speech audibility. The current study investigated 78 children from ages 1.3 to 21.6 years (M = 10.6 years) who wore DSR hearing aids. These hearing aids provided significant improvements in pure-tone average (PTA; mean improvement for the aided versus unaided condition of 49 dB) and high-frequency PTA (mean improvement for the aided versus unaided condition of 56 dB). A subgroup of 19 children were previous users of conventional hearing aids. These participants demonstrated a mean improvement of 11 dB in PTA and 12.5% in word recognition scores for DSR versus conventional amplification. However, DSR hearing aids required repair 3 times as often as conventional hearing aids. The greatest benefit was observed in children whose word recognition scores were poorest using conventional hearing aids.
