Abstract

Real-ear measurements has allowed the audiologist to have a criterion for assessing the adaptation of reliable and valid instruments. The use of these measures in estimating the goodness of adaptation allows us, among other advantages, to take into account individual differences by providing parameters related to the performance of the hearing aid in real ear. In this article we will carry out a review of the main measurements that can be recorded with a real ear audio analyzer and microphone probe and their main applications.
