Jacoti Inside: Hearing personalisation on BT Audio SoCs

Jacoti Inside Logo

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.
