Alternative Metrics for Real-Ear-to-Coupler Difference Average Values in Children

Abstract

Head circumference can be considered as a metric for RECD prediction in children when individual measurements cannot be obtained. In developing countries where equipment is often unavailable and stunted growth can reduce the value of using age as a metric, head circumference can be considered as an alternative metric in the prediction of RECDs.

“…Continued development and dissemination of strategies for maintaining consistent earmold RECD values throughout the assessment and verification process; 3. Alternative options to performing two separate RECD measurements (at assessment and at verification) should be investigated (Yanz et al, 2007;Blumsack et al, 2014;Moodie et al, 2014; see Moodie et al, 2016); 4. Revision of AAA CPGs (AAA, 2012; to discuss relevancy and use of RECD values during both the hearing assessment and hearing aid verification processes; and 5.…”
