Frequently asked questions
What is Voice over New Radio (VoNR)?
VoNR is the next generation of voice services for 5G networks, replacing Voice over LTE (VoLTE). This technology requires specific HAC testing to ensure compatibility with hearing aids and meet regulatory requirements.
What specific measurements are included in HAC testing?
Our comprehensive testing covers RF Electric-field emissions, RF Magnetic-field emissions, T-coil mode measurements (magnetic-signal strength, frequency response, and noise articulation index), and Volume Control testing (conversational gain, distortion and noise, frequency response).
What are the new requirements for VoNR devices?
VoNR devices must meet updated standards including proof of hearing-aid compatibility, new Volume Control test requirements, T-Coil testing specifications, and updated RFE test procedures and labeling requirements, particularly for US and Canadian markets.
Do you support products at different development stages?
Yes, we provide testing and certification for devices both in development and currently on market, ensuring stand-alone functionality and regulatory compliance at any stage of your product lifecycle.
