Software-Defined Hearing

In 2018, Lyratone introduced the concept of Software-Defined Hearing methodology and architecture, aimed at revolutionizing the next generation of hearing aids. These innovative devices are designed to be highly customizable, offering greater flexibility and agility in incorporating cutting-edge technology. Through software control and updates, they dynamically adapt to varying levels of hearing loss and changing environments, ensuring optimal performance for users. 

With Software-Defined Hearing, we exert precise control over the core functions of hearing aid sound processing through software. These functions encompass WDRC, noise reduction, feedback management, and fitting. The central premise is to abstract the traditional hardware-dependent functions of hearing aids into a software layer. 

In Software-Defined Hearing, all aspects of hearing functionality are governed and managed by this software layer, thereby revolutionizing the conventional paradigm of hearing aid technology. 

Technical Architecture of Software-Defined Hearing

Unlike traditional hearing aids that rely on ASIC (Application Specific Integrated Circuit) technology, where hearing functions are embedded within the integrated circuit, Software-Defined Hearing abstracts these functions from ASIC into a software layer. This paradigm shift enables the control of the hearing process through software rather than hardware configuration.

By leveraging software characteristics, the Software-Defined Hearing architecture offers enhanced flexibility in performance improvement, open integrations, and cost efficiency compared to its hardware-centric counterparts.

Enhance User Experience

Software-Defined Hearing aid can be customized according to individual needs, preferences, and hearing conditions by softwareizing the core functions of hearing aid. This enables a personalized listening experience. With the continuous advancement of technology,  software-defined hearing aids can be upgraded through OTA, allowing hearing-impaired users to enjoy the continuous listening experience improvement brought by the latest algorithm technology.

Reduce R&D Cost

By separating the hardware layer and application layer, hearing aid companies can focus on the development of hearing algorithms, rather than the SoC chipsets. This greatly reduces the R&D iteration cost of the core functions of hearing aids.
