Audioscan Verifit 2 OTC/DTC Test Suite: What You Should Know


Audioscan introduces the OTC (Over the Counter) / DTC (Direct to Consumer) Test Suite for Verifit2. By answering key questions, here is what you need to know about this new software feature.

The Audioscan OTC/DTC Test Suite is a recent addition to the Verifit2 software, available in software version 2023.2.2. This new feature provides a means to assess the performance and audibility of OTC/DTC devices.

This new feature brings several advantages to clinical practice.

With the test results, clinicians can inform and counsel existing OTC device users about the quality and suitability of their devices. This opens the door for professional guidance, including prescribing hearing aids, especially if users are unsatisfied with their devices.

Additionally, it can measure the safety and utility of Personal Sound Amplification Products (PSAPs) and hearables, which are not FDA-regulated.

This tool can also aid clinics in expanding the range of technology options they offer. By confirming the safety and utility of the products, clinics can cater to a broader audience with varied needs and budgets.

The suite integrates the FDA's electroacoustic test battery, which is founded on consumer safety criteria. This safety criterion mandates manufacturers to collect and disclose a set of electroacoustic measurements and test results for all OTC products.

This standard relies on both the ANSI/CTA-2051 and ANSI S3.22 hearing aid measurement standards. It is important to note that this framework does not extend to Personal Sound Amplification Products (PSAPs) since they operate without FDA regulation, and compliance with ANSI/CTA-2051 standards is entirely optional.

The FDA consumer safety electroacoustic test battery and its associated performance criteria is embedded in the Audioscan OTC/DTC Test Suite.

Verifit2 users can access these tests by selecting the OTC/DTC menu option, available in software version 2023.2.2 or later. The OTC/DTC Test Screen displays frequency response graphs, making it easy to evaluate performance. Once the ANSI/CTA-2051 Evaluation test sequence is completed the OTC/DTC will be given a green check mark if the device measured meets FDA ruling criteria per ANSI/CTA-2051 methods.

Various OTC styles can be tested using different coupling techniques. For example, receiver-in-the-canal or thin tube-styled OTC devices can be coupled using TRIC adapters, while in-ear or earbud-styled devices can be coupled with blue putty.

The Audibility Evaluation is an added feature that is not mandated by the FDA. This test suite feature assesses if devices provide meaningful speech amplification for mild-to-moderate hearing loss, comparing their performance with established fitting targets, either the DSL 5.0a fitting rule or the NAL-NL2 fitting rule.

The Audioscan OTC/DTC Test Suite is a valuable tool for hearing health professionals, offering the means to verify the suitability of OTC devices, and provides sound evidence for the need to fit prescribed hearing aids.
