CN-121985276-A - Hearing assistance device, method, system, storage medium and product

Abstract

The application discloses hearing assistance equipment, a hearing assistance method, a hearing assistance system, a storage medium and a storage product, and belongs to the technical field of hearing assistance. The application realizes data-driven self-adaptive hearing assistance without manually debugging equipment parameters or switching hearing assistance modes by a user. Wherein the capability release of the signal processing unit is controlled by a dynamic signal processing parameter envelope. The boundaries of the parameter envelope are dynamically determined by confidence levels. In this scheme, the confidence calculating unit continuously acquires the reference data and calculates the confidence according to the reference data. Accordingly, the parameter envelope controller may dynamically adjust the boundary of the parameter envelope according to the real-time value of the confidence coefficient, thereby determining the current feasible parameter domain. Based on the above, the signal processing unit can process and output the audio signal in the feasible parameter domain, so as to realize accurate hearing compensation. The scheme not only reduces the operation cost of the user, but also realizes smooth transition of hearing aid functions, and the whole process cannot be interrupted.
