Design win; Bluetooth LE IP advances hearing aid performance

August 24, 2016 // By Graham Prophet
Designer and supplier of DSP and wireless IP for SoCs, CEVA, has disclosed that hearing aid maker Oticon has licensed its Bluetooth Low Energy technology. Oticon has developed technology it calls BrainHearing, and applies CEVA’s RivieraWaves Bluetooth technology to implement direct streaming between its Oticon Opn hearing aid and smartphones, DTVs and other devices.

Oticon Opn combines technologies to “help people with hearing loss hear better, with less effort and better recall” including the innovative TwinLink technology which incorporates both binaural processing and direct connectivity into a single hearing aid design. This combination of binaural processing and 2.4 GHz Bluetooth connectivity is developed by Oticon as a dedicated hearing aid solution and allows the Opn hearing aid to directly connect to external Bluetooth-enabled devices, including smartphones and TVs.


“Bluetooth low energy is a critical, differentiating feature of our Opn hearing aid, allowing our customers to directly connect and stream audio between their Bluetooth-enabled devices for a significantly enhanced user experience,” said Finn Möhring, VP of R&D at Oticon. “We chose CEVA’s RivieraWaves BLE technology as an important component of the Bluetooth connectivity solution of Opn due to its winning combination of market leadership, quality of IP and excellent technical support.”


The RivieraWaves Bluetooth IP platforms consist of a hardware baseband controller, plus a software protocol stack. For Bluetooth Low Energy, this protocol stack encompasses the Link Layer up to the GAP/GATT plus a comprehensive set of Services and Profiles. For Bluetooth Dual Mode, this protocol stack presents an industry standard HCI interface. A flexible radio interface allows the platform to be deployed with either RivieraWaves RF or various partners’ RF IP, enabling optimal selection of foundry and process node.
