Title: The Innovative Contributions of Bhaskar Dharanipragada Rao
Introduction
Bhaskar Dharanipragada Rao, an accomplished inventor located in San Diego, CA, has made significant strides in audio signal processing. With a total of nine patents to his name, his work primarily focuses on enhancing the effectiveness of hearing aids and feedback cancellation technologies.
Latest Patents
Among Bhaskar's latest innovations are two notable patents that showcase his expertise in mitigating acoustic feedback in hearing aids. The first patent involves a method and system for processing audio signals by dividing an audio signal into multiple frequency sub-bands. In this process, each sub-band is further divided into overlapping temporal frames, with frequency warping performed on each frame before they are recombined to produce a frequency-warped signal.
The second invention introduces a sparsity-aware adaptive feedback cancellation system. This device uses input transducers to convert signals while an adaptive feedback estimator is employed to create feedback compensation. The estimator includes processors and machine-readable mediums that enable an advanced method to estimate feedback path characteristics, construct adaptive feedback cancellation filters, and generate feedback estimation signals to improve output quality.
