How to Use the Repeat-Recall Test (RRT) to Increase Hearing Aid Satisfaction
The RRT is an integrated speech test that provides a platform for individualized counseling. The goal is to provide a better understanding of each patient’s communication difficulties, then use that understanding to set realistic expectations. We believe the use of this tool, along with other tools that allow individualized fine-tuning, could help promote greater patient satisfaction for hearing aids.

Development and Clinical Applications of the ORCA Repeat and Recall Test (RRT)
A broader appreciation for the unique difficulties faced by many of our patients relative to speech understanding in noise and working memory is critical to tailoring individualized interventions that help them realize the full potential of their residual hearing. At present, the Repeat and Recall Test (RRT) shows promise as an efficient, audiology-based integrative tool of speech-in-noise assessment that includes a more complete understanding of a listener’s experience in a loud speech background at various realistic SNRs.
A Comparison of Feedback Cancellation Systems in Premier Hearing Aids
This study, which replicates earlier research on feedback cancellation (FBC) systems, uses three tests to evaluate the various aspects of hearing aid performance directly affected by the FBC: AGBF, Max-REIG, and a sound quality evaluation using Multi-Stimulus Test with Hidden Reference and Anchor (MUSHRA).

Using Tracking of Noise Tolerance (TNT) as an Outcome Measure for Hearing Aids
The TNT is a reliable and efficient clinical test that allows measurement of a hearing-impaired listener’s tolerance for noise—with and without hearing aids—so that the results can be compared to normal-hearing listeners, among various hearing aid features, and on the same individual over time. This tool may also be useful for estimating potential satisfaction of the fitted hearing aids in real-life noisy environments.

Field Trial Tests the Sound Quality of ReSound LiNX 3D
In a field trial where recent purchasers of ReSound LiNX2 were refit with ReSound LiNX 3D, subjective outcomes were slightly but significantly improved for ReSound LiNX 3D, with 70% of participants expressing a preference for the sound quality of the newer hearing aid.

Towards a Firm Grip on Auditory Reality
What is a realistic SNR and how should we test and assess features such as noise reduction algorithms? This article presents two studies that emphasize the importance of auditory reality on the design, fitting, and evaluation of hearing aids—with the hope of moving towards a firm grip on auditory reality.

A New Own Voice Processing System for Optimizing Communication
The new Signia Nx hearing aids contain Own Voice Processing (OVP™) technology designed to identify when the wearer is speaking. In this way, OVP can employ dual processing for either speech or own-voice conditions.
