National Acoustic Laboratories (NAL) and MedRx have partnered to bring the next-generation NAL-NL3 fitting formula to MedRx’s verification and testing systems. The integration—now available in MedRx Studio Software version 1.3.2—marks one of the first implementations of NAL-NL3 worldwide and reflects the longstanding collaboration between NAL, MedRx, and the broader Demant Group.
The update gives hearing care professionals access to NAL’s newest evidence-based fitting system, designed to optimize speech intelligibility and listening comfort across a wide range of hearing needs. MedRx Studio v1.3.2 now incorporates NAL-NL3 into both verification and testing workflows, allowing clinicians to apply the latest research directly within their existing tools.
Key Highlights of the Integration
- NAL-NL3 is the latest evidence-based fitting system designed to optimize speech intelligibility and listening comfort.
- MedRx Studio v1.3.2 now supports NAL-NL3 across REM/LSM and HIT workflows.
- Compatibility includes MedRx AVANT HIT+, AVANT REM+, AVANT ARC, WREM, and AWRC systems.
- Clinicians can verify fittings using real-ear measurements and confirm device performance in the HIT box—both aligned to NAL-NL3 targets.
This release underscores how research–industry collaboration accelerates access to evidence-based tools for hearing care professionals worldwide.
Brent Edwards, PhD, Director of the National Acoustic Laboratories, noted that the addition represents a major milestone:
“This makes MedRx the first verification systems globally to integrate and offer the NAL-NL3 Fitting System, including the two new modules for special use cases. Clinicians now have access to the most advanced fitting formula available today, helping them deliver even better outcomes for people with hearing difficulties.”
Caleb Sparkman, President of MedRx, emphasized the company’s commitment to clinical best practices, adding: “MedRx is committed to delivering cutting-edge tools for hearing care professionals. Integrating NAL-NL3 into our software reflects our dedication to best practices and innovation.”
The integration highlights how research-driven development and strong industry partnerships can provide clinicians quicker access to new advancements in fitting accuracy and patient-centered care.
Clinicians can access NAL-NL3 by updating to MedRx Studio Software v1.3.2. More information is available at nal-nl3.com.au and medrx-diagnostics.com.
