Jacoti Inside: Hearing personalisation on BT Audio SoCs
Jacoti has developed and optimized its processing engine for Qualcomm's QCC51xx and Tensilica's HiFi DSP series, enabling hearing devices like earbuds, headsets, and hearing aids to perform personalized hearing tests and adjust audio output to the individual's needs. With this technology, product manufacturers can seamlessly integrate Jacoti's hearing assessment and audio personalization technology into their products at the chip level.
By bringing our science-based precision to Qualcomm's Bluetooth Audio SoCs and Tensilica's HiFi DSPs, Jacoti can meet increasing consumer demand for hearing enhancement-capable earbuds. Hearing algorithms and correction parameters are directly embedded in the earbuds.
Deep-embbeded Hearing Technology
Reliable and consistent hearing test
Jacoti's hearing test is designed to be user-friendly and accurate, using a patented two-tone procedure (Duo-Tone) that tests hearing discrimination. The results are based on a full spectrum calibrated audiogram, which we present to users in a simplified way to help them better understand their hearing abilities. The test is clinically validated as comparable to current audiologist practices and has received CE marking and Class IIa Medical Device approval, ensuring its safety and reliability.
Jacoti Duotone® test procedureAudio personalisation
Jacoti's hearing system is designed to work seamlessly with earbuds, providing users with personaliSed sound in real-time with minimal delay and can compensate for hearing challenges over a very wide bandwidth (up to 24 kHz). It is suitable for those with mild to moderate hearing losses. The technology uses advanced algorithms to adjust sound for various listening modes such as music, speech, and natural sound.
Jacoti HearingKit®Data storage and remote fitting
Consumer's hearing data is stored on earCloud's secure server platform. Their hearing performance is accessible for tracking and, on consumer authorisation, also accessible remotely by hearing specialists (with permission to access controled by the user).
