Demystifying REM Verification for Non-Occluding Fittings
Does the real-ear unaided response need to be subtracted for non-occluding fittings? What about Speechmap/SPL-o-gram methods?

Compatible with Starkey’s REM Target Match tool, the Inventis Trumpet is “capable of performing quick and accurate in-situ measures thanks to its small and lightweight probes and its built-in amplified speaker,” according to the company's announcement.
A new software-assisted system for placement of the probe tube in real-ear measurement (REM) has been developed by Audioscan. This article describes the new Probe Guide tool and compares its performance with traditional methods for probe tube placement.
Before jumping to the conclusion that any PSAP and/or future OTC hearing device would be suitable for the many different types of hearing losses, we need to look at their coupler and real-ear performance data. This study by Adam Voss, Kristi Oeding, AU Bankaitis, John Pumford, and Michael Valente suggests current PSAPs are suitable for mild losses only.
Read MoreNow that we’ve defined (at minimum) what an OTC hearing device should look like, maybe it’s time to start defining a minimal standard for what a professional hearing aid fitting should look like.
Read MoreValente et al found that 79% of the study participants preferred the programmed fittings using REM versus the first-fit. They conclude that “Using a first-fit alone without reprogramming using REM is fitting hearing aids blindly and not determining whether the patient is being provided appropriate audibility for soft and average speech…The audiologist or hearing aid dispenser can never be certain if he/she is appropriately fitting the patient without using REM.”
Read MoreIt’s time to clearly distinguish professional service from self-service by showing why licensed hearing care professionals can make a huge difference in hearing aid outcomes. Let’s commit to getting consumers a list of essentials by creating a voluntary standard protocol for every licensed professional who dispenses hearing aids. Let’s spell out what consumers should expect. And then let’s promote the hell out of it.

Topics include research at NAL, the NAL’s cortical auditory evoked potential (CAEP) system known as HEARLab, over-the-counter hearing aids, and more.
Read MoreIn this new era of disruptive technology, hearing care practices need valuable information to help increase the knowledge of decision makers. Primus Business Analytics is designed to help owners and managers effectively identify growth and development opportunities, understand best-practice protocols, the duration and scope of testing, and assist in fine-tuning in ways that would otherwise be virtually impossible.
Read MoreThis study looks at how advanced hearing aid features may affect the results of routine real-ear measurement (REM). One of the key points is that, by using speech noise stimuli (like the ISTS stimuli) during REM, you should be able to obtain an accurate representation of speech gain while not having to turn off all of the advanced features.

Read MoreVerification of a hearing aid (or hearing protection) fitting is an obvious usage, but it can be quite instructive about some general acoustic principles.
Read MoreDr Valente is the author and co-author of four books, and is a well-known authority on audiologic testing, hearing aid fitting, research, and single-sided deafness.
Read MoreA study that assesses both the test-retest repeatability and the precision (matching accuracy) of the new Phonak TargetMatch system.
Read MoreThis article looks at how differences in the level of audibility provided by each fitting approach—REM vs Quick Fit—impacts speech understanding and, indirectly, patient loyalty towards the provider.
Read MoreDouglas Beck, AuD, interviews long-time educator and clinician Ted Venema, PhD, about the issues surrounding hearing aid compression, inner and outer hair cell loss, digital noise reduction, speech in noise, and verification.
Read MoreThe areas of speech mapping, probe-microphone measurements, and the verification of prescriptive targets continue to be important topics in hearing aid dispensing and hearing healthcare.
Read MoreReal-ear verification is considered a “best practice” when fitting hearing aids. In this study, a clinical verification approach was applied to verify the implementation of the NAL-NL2 rationale in the Widex Unique hearing aids.
