OTC and AAA, ADA, IHS, and ASHA: Now That We’re All on the Same Page…
It’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.

Hearing Aid Programming Practices in Oregon: Fitting Errors and Real Ear Measurements
This study shows that 97.7% of subjects showed deviations from the NAL-NL2 in excess of 5 dB in both ears—well in excess of the nearly two-thirds of hearing aid fitting errors reported by the now-famous Consumer Reports article of 2009. Research continues to show that hearing aids that provide more real-ear verified aided speech audibility result in better outcomes than hearing aids that do not provide as much aided speech audibility.

Teleaudiology: Friend or Foe in the Consumerism of Hearing Healthcare?
In Part 2 of this 2-part article, Tammara Stender, Jennifer Groth, and David Fabry address how teleaudiology can provide better fit-to-preference and efficiency in hearing healthcare. Today’s wireless and hearing instrument technology affords HCPs even more opportunities to quickly meet hearing needs. The obvious solution to the “user fit-to-preference versus time constraints for both users and professionals” dilemma is a hearing fitting protocol that marries the personal and professional interactions so important for user satisfaction with the convenience of user-driven services, such as apps or secure cloud connections.

Improving Patient Perception of Clinical Services Through Real-ear Measurements
This study assessed the impact of REMs on consumer satisfaction as a service component during hearing aid fittings. For the SERVAL scale, overall results revealed that the REM protocol reduced emotional distress, and improved perceived quality of service and value of the fitting compared to the Quick-fit protocol in 3 groups of participants.

Understanding How RECDs Fit into the “Big Picture” of Hearing Aid Fitting
Since the introduction of real ear measurement systems, real-ear-to-coupler difference (RECD) measurements have become a clinical reality. Understanding the RECD and how it is used in hearing aid fitting software allows clinicians to better define fitting protocols for individual listeners.
