fitting hearing aids without Real-Ear

As an audiologist working at a facility that sees a large pediatric population, 
we find real ear measures to be vital.  In this population, there are a number 
of obvious factors that limit our ability to obtain subjective information 
regarding the HA fitting.  In addition, the small size of the ear canal and 
resulting increase in SPL in the ear canal make it very important that we make 
those measures imperically.  Being able to assess the audibility of speech 
across a variety of input levels is important for this population, who are 
learning speech and language, also.  I could go on and on about the advantages 
of real ear in the pediatric population, but you get the idea.  Real ear 
measures are not the end of the fitting with children (or adults for that 
matter) but they are an important part of the complete picture.
