Conventional hearing aids use proprietary chips that provide limited consumer-level feature sets. By embedding Jacoti HearingKit® modules in the same QCC51xx and Tensilica's HiFi DSP series SoCs used in premium true wireless earbuds and other consumer technology, the audio signal can be processed as well as even better than with conventional hearing aid chip:
Our Jacoti DuoTone® hearing test has been validated against Pure Tone audiometry done in clinic. The Jacoti DuoTone® hearing test is part of the Jacoti Inside solution and is implemented on the True Wireless Earbuds incorporating our technology.
Based on the unique hearing profile of a user, Jacoti HearingKit® automatically computes hearing loss fitting parameters by using well-established fitting rules and extending them to take advantage of a higher bandwidth than that found in conventional hearing aids.
Literature (1, 2) shows that there are significant trade-offs with using multi-channel WDRC. For example, fittings are often unnecessarily complex. In addition, since multi-channel WDRC partially flattens spectral shapes, it creates unwanted distortion side effects for some hearing losses.
