![]() Volume control is a new test area where compliance is a significant challenge due because this requirement was not considered in the design process for new devices. This better reflects real-world usage and gives the user a better experience but makes the test more difficult to pass.ĪNSI C63.19-2019 also introduces brand-new test requirements that likely have not been previously tested or investigated. For example, ANSI C63.19-2019 has revised T-coil requirements with spatial thresholds to ensure that hearing aid users experience good audio performance when holding their handset in different positions, rather than a single narrow point. This is a sensible approach but requires greater testing complexity and therefore creates a more challenging certification process. Many of the changes to the standard attempt to more realistically address how hearing-impaired users may interact with their devices. To bring products to market on a competitive timeline, it is important for manufacturers to be aware of these changes and to choose a testing partner with a complete and up-to-date understanding of HAC testing requirements. This revision of the standard introduces entirely new requirements and modifies existing procedures for how hearing aid compatibility is tested and evaluated. This standard plays a major role in dictating how communication devices are tested for hearing aid compatibility (HAC), and what functionality requirements manufacturers must account for before sending a product to market. The transition period between the old and new versions of the standard ends on June 4, 2023, after which point the 2019 version is required for FCC HAC certification. ![]() ![]() In late 2019, the American National Standards Institute (ANSI) published a revision to standard C63.19, which addresses compatibility between mobile handsets and hearing aids.
