Evolving from One Formula to a Modular Fitting System

NAL-NL2 was a single formula, but the NAL-NL3 Fitting System offers a general Prescription plus specialized Modules, chosen to fit each patient's individual needs. Its modern, modular system is built on hundreds of thousands of real-world fittings, and uses machine learning to handle complex listening environments and different hearing profiles.

NAL-NL3 PRESCRIPTION

Available Now
Refining & Elevating a Trusted Solution

The NAL-NL3 Prescription refines the NAL-NL2 philosophy, improving this trusted solution. Leveraging machine learning and 10+ years of NAL-NL2 data across hundreds of thousands of fittings, it addresses known clinical pain points.

The NAL-NL3 system is an advancement over one-size-fits all formulas, introducing the ability to provide additional evidence-based modules for specific real-world listening needs, enhancing accessibility and effectiveness in hearing care.

Comfort in Noise Module

Coming in 6.7.0
Comfort in Noise, Kept Intelligible

The Comfort in Noise Module optimizes listening comfort in noise without giving up intelligibility. It reduces listening fatigue and improves comfort in noise without compromising speech clarity. Built on substantial speech-in-noise research, it offers the same fitting range as the Prescription.

NAL-NL3 Minimal Hearing Loss Module

Coming in 6.7.0
A New Solution For An Unmet Need

The Minimal Hearing Loss module helps patients who struggle to understand speech in noise but have a normal audiogram or minimal hearing loss. This first of its kind solution addresses a real-world and unmet need experienced by patients that may not meet criteria for traditional amplification.

An Independent Standard

A Modern, Evidence-Based Prescription

The NAL-NL3 fitting system is an independent, evidence-based prescription, not a manufacturer's black box. Get consistent, transparent targets, defensible to the NHS and any payer that expects you to fit to a standard.

It is built on machine learning, using an immense clinical dataset including hundreds of thousands of audiograms and more than one million real-ear measurements.

Replace the "best average fit" model with a gold-standard modular system, conveniently in the workflow you already use and trust.

“With their adoption of the NAL-NL3 Fitting System, Auditdata is making the gold standard fitting prescription available to more clinicians around the world. The NAL-NL3 Prescription was derived from millions of real-world fittings and audiologist insights to deliver a more precise first fit and best patient experience possible. NAL is excited to see Auditdata making NAL-NL3 Prescription and Modules accessible to its clinicians, enabling improved care for hearing aid wearers.”

Why choose NAL-NL3 over a proprietary formula?

The NAL-NL3 fitting system is an independent standard with consistent, transparent targets that you can explain and defend, rather than a manufacturer's own algorithm. It moves beyond one-size-fits-all formulas like NAL-NL2 to deliver customized fittings tailored to more diverse listening needs and environments.

How is NAL-NL3 different than NAL-NL2?

NAL-NL2 was a single formula, but the NAL-NL3 fitting system uniquely offers a general Prescription plus specialized Modules, adaptable to each patient's individual needs. This modern, modular system uses machine learning to handle complex listening environments and unique hearing profiles, using the same underlying philosophy as NAL-NL2. It is built on 10+ years of NAL-NL2 fitting data across hundreds of thousands of fittings.

Do I need new hardware?

No. The NAL-NL3 fitting system conveniently arrives as part of your Measure fitting workflow, beginning with the 6.6.0 release. This modular system expands what you can offer your patients, seamlessly integrating into the workflows and fitting software you already use.
