Jacoti optimises hearing experience on Qualcomm QCC51xx SoCs for users of true wireless earbuds

Jacoti has ported and optimised its processing engine for the QCC51xx series resulting in a low processing and RAM footprint and allowing Jacoti Hearing Technologies to be integrated on-chip. Hearing devices such as true wireless earbuds, headsets, and hearing aids based on this chip family can perform hearing tests as well as provide hearing loss compensation and audio personalisation.

“This collaboration with Qualcomm Technologies makes us able to integrate our audiologically-based hearing solutions into a powerful platform to improve the audio experience of all users. It will also help us realise our social mission to make state-of-the-art hearing solutions accessible and affordable for those with hearing challenges throughout the world.”

Audiogram-based hearing test

Jacoti's user-driven hearing test is based on a patented duo-tone procedure using sound discrimination. The hearing test results are shown in a full spectrum calibrated audiogram. It is designed in full compliance with audiometer ANSI standards, making it clinically validated against current audiologist practice, besides being CE marked and approved as Class IIa Medical Device.

Hearing personalisation

Jacoti hearing system runs inside the earbud leading to latency < 12 msec and algorithmic latency ~ 3msec, compatible with Qualcomm ANC. It affords full-bandwidth compensation up to 24kHz, gains suitable for mild to moderate hearing loss consumers, and uses NAL-based prescription formulae – with plans to extend. Jacoti hearing personalisation works in streaming, ambient and live modes and allows program adjustment for movie, music speech and natural sound.

Data Storage and remote fitting

Consumer audiograms are stored on the server platform. Their hearing performance is accessible for tracking and, on consumer authorisation, also accessible by remote audiologists. Hearing experts can support consumers in real-time and optimise fittings, adjusting the first line parameters – Prescription gain, compression/expansion ratios, level detectors, etc.
