Interestingly both Widex with the senso and Oticon with the Digifocus
are advising that REM  is not used when fitting the instruments due to
the 'complexity of the algorithms operating the DSP chips. Both these
instruments have a 'test mode' which is used for QC checking.  It does
seem a little unfortunate that we spend such a lot of time and money
investing in state of the art measurement equipment to the benefit of
both ourselves and our clients only to find that using the latest high
technology hearing instruments makes it obsolete.
