Latest Patents

Fred Harris holds a patent for a remarkable invention titled "Mitigating acoustic feedback in hearing aids with frequency warping by all-pass networks." This invention provides a sophisticated method and system for processing audio signals in hearing aids. The process involves receiving an audio signal and dividing it into multiple frequency sub-bands. Each sub-band signal is then subdivided into overlapping temporal frames, which are windowed for further analysis. Frequency warping is applied to these windowed frames, followed by an overlap-and-add technique. The result is a combined full band that generates a frequency warped signal, effectively addressing acoustic feedback challenges in hearing aids.
